Educational Toys For Kids

A parent's greatest contribution to a child's educational growth should come before the child ever begins his formal education. Parents can leave it to the schools to teach their child to read or count or write his name. But a child's best educational opportunities and future growth depend on the combined effort of parent, teacher, and student.

There is a world of difference in the child whose parents are actively involved in his learning, and the child who is totally left on his own. It's a difference not only in ability, in quality of work, but also in attitude and self-image. A child's first school is the home, so the toys that his parents select for him should not only keep him amused and occupied, but also develop his physical, mental and emotional well-being. The market for educational toys has thus been opened.

Educational Games For Toddlers

Mainly addressing the clamor for toys accepted by child psychologists, toy manufacturers have come up with a wide array of toys that promise hours of fun and excitement to the child, and at the same time, meet the requirements set by these experts.

If it is true that no one ever steps into the same river twice, it is also true that no child ever plays with the same toy twice. As the child enters each stage of growth, his play changes; and as his play changes, the toy is also transformed. Psychologists have studied the evolution and development of a child's intellect, as pioneered by Swiss psychologist Jean Piaget, by closely observing children. They have come out with a trove of realities on how toys, educational or otherwise, affect the child's multiple intelligences.

An interesting sidebar to these findings is the fact that toys and toy advertising have powerful effects on the ways children construct their gender identities. Girls between the ages of five to eight who are exposed to Barbie dolls feel worse about their bodies than girls exposed to dolls with more realistic physiques. Female-stereotyped toys tend to promote the most complex play in 18 to 47 month-olds. But as children grow older, their gendered stereotypes about toys grow stronger. Boys, especially, become increasingly likely to avoid playing with "girl toys," possibly for fear of social repercussions from their peers. Thus, those fashion dolls that were created towards the teens and pre-teens segment to supposedly stimulate creativity and encourage imagination, may not really be the best educational toys because they encourage gender marginalization and desensitization. Both strongly feminine and strongly masculine toys seem to be associated with the worst aspects of gender roles: i.e., a focus on appearance in girls and violence in boys.

Toy companies, like all other businesses, aim towards making money. But unlike many other businesses, the target market of the toy industry is children who are not amply fortified with the capacity to dispute these companies' claims or question the significance of their offers. The fact that the toy manufacturers sell directly to a key market that depends on middlemen - their parents - to purchase the products, is in itself a remarkable curiosity.

The result is an abstruse circumstance wherein toy companies contend that they are protecting the children's purchasing rights through straightforward advertising, whereas critics argue that these companies are exploiting a defenseless population.

Free Toddler Activities You Can Do at Home

2012-01-01T03:15:00.000-08:00

Toddlers love to try new things, but it is often difficult for parents to come up with ideas for activities to entertain them at home and they end up getting stuck in a rut, doing the same old activities with their children on a regular basis. Below are a few ideas to spark your imagination.

Make a rain stick

Educational Games For Toddlers

Most people will have wrapping paper in their house at some point and there is an easy and fun craft activity you can do with the empty tube, baking paper, rice and a couple of elastic bands - making a rain stick! An empty kitchen roll can be used to make a mini version.

First of all, let your toddler decorate the tube. This can be done by painting it, sticking things on it or even covering it in old wrapping paper. Next you will need to cut out two circles from the baking paper which are slightly wider than the end of the tube. Fix one of these circles to the end of the tube by securing it with an elastic band.

The next step is to add the 'rain'. You can use rice, small pasta shapes, little shells or any other objects which could be used to make a satisfying rain sound. Once you have poured a handful of rice (or alternative) into the tube you need to seal the other end with the second baking paper circle and elastic band. The rain stick is finished - to work it tip it slowly backwards and forwards.

Pebble pets

For this activity you will need some paint, PVA glue and a pebble - technically this activity is not free as you will need to buy the paint, but I have included this activity in the article as most homes with young children already have poster paint and it is cheap.

The pebble needs to be fairly large and round. The simplest design is a ladybird, but your toddler can paint whatever takes their imagination. Mix a little PVA glue with red poster paint and completely cover the pebble. This will then need to be left for a couple of hours. Once it is completely dry your child can use black poster paint to add spots and a face. If your toddler is young or impatient you may wish to paint the initial layer without them and then give them it to decorate, so they are not frustrated while waiting for it to dry.

Instead of black poster paint you could instead use a black marker pen, if you have one, and googly eyes can add a fun touch.

Play dough

This can be made for free using ingredients found in most homes. Combine 1 cup of plain flour with half a cup of salt and 1 teaspoon of cream of tartar in a saucepan. Mix it together over a low heat while gradually adding 1 cup of water. Remove from the heat once it has combined into a sticky ball. Leave it to dry for a couple of hours before allowing your toddler to play with it.

Blowing bubbles

Toddlers love bubbles and this activity is good for them too. In learning to hold the bubble wand correctly and blow bubbles they are learning about coordination and following simple instructions. It can also be a good physical activity if you blow the bubbles while your child jumps around trying to pop them.

You don't need to go out and purchase bubble solution and a wand as they are very easy to make using items found around the home. Bubble solution can be made by mixing one cup of water with 4 tablespoons of washing up liquid (liquid detergent). Glycerine (2 tablespoons) can be added to make longer lasting bubbles but it is not a necessity. A simple bubble wand can be constructed by cutting the centre out of a plastic pot lid and attaching it to a straw with tape.

Treasure box

Putting together a treasure box doesn't take long and need not cost you a penny. It is great for imaginative play, as I'm sure many parents have noticed that their child is often more interested in playing with every day household objects than their toys.

You will need a box or bag to store the objects in, for example a shoe box or empty and washed ice cream tub. Look for objects around the home which are child safe and which you do not mind your toddler playing with. Ideas include an unused make-up brush, a whisk, a wooden spoon, an empty toilet roll, unwanted jewellery and old mobile phone (battery taken out).You can also look outside for inspiration such as pine cones and feathers. Simple objects can keep a toddler entertained for many happy hours!

There are many sites devoted to toddler activities and these can be used to inspire you. Once you start trying new things with your toddler you will find that ideas for further activities start flowing much more easily.

Alphabet games: Here the main aim of the games is to teach the letters to the toddler. Usually the toddler has to press the corresponding letter on the keyboard and when it done correctly, images of items starting with that letter come up on the screen. With the help of images, a toddler can learn the alphabet in a relaxed and fun way.

Roll-over games: These games are specifically designed to improve the hand-eye co-ordination. The games are designed in such a manner that the toddler has to move his or her eyes in all the directions and also move his or her hands in the same direction as the eyes. These games also help to improve the concentration ability of the child.

Shape matching games: Here, the toddler has to match the shape of the image displayed. It is a simple and fun way of teaching the various shapes to the toddler. In fact, several of these games are available for free on the Internet.

Older children might enjoy games such as ghoul and fright or other scarier Halloween themed games while younger kids might find them too frightening or complicated to consider. Toddlers tend to really love pumpkins so any game with a pumpkin as a theme will generally retain a toddler's rapt attention. Toddlers also tend to prefer short games with few rules. You can even use the same game with different themes and toddlers will tend to remain well entertained. Marshmallow bobbing, scavenger hunts and the Monster freeze dance are also great fun for your smaller partygoers.

Preschool Learning Activities-Emotional Development & Fine Motor Skills Activities

2011-12-26T12:17:00.000-08:00

Preschool learning activities are varied and just involve a little creativity. Emotional Development activities for kids as well as Fine Motor Skills Development are very important areas to develop in your child or preschooler.

Having your preschool child cut out various shapes and objects is a great way to help develop fine motor skills. Of course if you are going to allow your children or preschoolers to do this activity you need to ensure they are using the proper 'child safe' scissors when doing ANY cutting in any material.

Educational Games For Toddlers

Here is a fun preschool learning activity that you can use with your preschool child to help develop them in these specific areas of growth. Keep a collection of old magazines, newspapers or flyers that are full of images of people with different expressions etc.

Preschool Learning Activities-Emotional Development & Fine Motor Skills Activities

Instruct the children to pick a magazine or newspaper etc. to look through and find images of people's faces showing different expressions. They may find pictures of happy faces, sad faces, surprised faces, angry faces, scared faces and many more.

Your preschool child can then 'cut out' all the faces they find using 'child safe' scissors of course, and they can discuss each different image with the parent or teacher and discuss what they see in the person's expression. You could even just have children find and cut out a certain expression, or what 'they' see as a certain expression. For example, you could tell them to find any pictures of 'happy faces' and see what they come up with, you may be surprised what they find!

It is good to keep these images and glue them to a piece of Bristol Board or construction paper, and then to laminate it. You can then cut them all out and save them in a box or envelope! This will make the images last for years so they may be used again and again in many different ways to teach children. You could even use these different faces and expressions and have children 'GROUP' all similar expressions together in a pile.

Another Great learning activity for children becoming familiar with spelling and simple reading or word recognition would be to have a few different images (4-6) out. You could then have the names of the expressions written on a piece of paper or a label (example) Happy, Sad, Angry etc. You could have the child(ren) match the image to the word. This is excellent for simple reading and recognition of every day words that express emotion.

Computers have become a common and needed part of life in today's society, making computer education imperative for children. Young children will typically begin to show an interest in the home PC by their toddler years. While it is may be a good idea to begin introducing your toddler to the computer in very short sessions, most children can began to learn and understand a computer's functionality by preschool age.

Preschool age children can learn to turn the computer on by themselves and will quickly learn to operate the mouse. Simple games that teach and reinforce basic school readiness skills are great for this age. Computer education for preschool age children should be limited to short sessions of about 30 minutes a few times a week.

Educational Games For Toddlers

Many childcare facilities offer computer time as part of their weekly curriculum for preschoolers. Structured games and activities give young children an opportunity to explore the way a computer works. Games that require dragging objects across the screen are excellent for building mouse skills in beginner users. Chose age-appropriate software and websites that involve alphabet and color recognition, shapes, counting, or short stories that are read aloud. Activities that feature music are also enjoyable for a preschooler's computer time.

Kindergartners are normally still exploring the basics of computer use and will probably do best with activities that reinforce simple skills. As children become more comfortable with the computer, more complex games and activities can be introduced. Computer education for kindergartners typically consists of short sessions of no more than an hour, playing games that correlate with their classroom learning material.

By first grade, children have usually gained a good understanding of how to use a mouse and they are learning to use keyboard letters to type. Games like Typing Instructor for Kids can help young children become fast and efficient computer users. Early elementary age children are ready to move beyond simple reinforcement and skill drill activities to the many different functions of a computer.

First through third graders should use the computer as a supplement for their classroom work. A student studying about stars and planets can use the internet to search for pictures and information about constellations. An assignment about Africa can include a search for videos of African animals. Allow your child to work on his own, but stay close by to prevent access to inappropriate content and to answer any questions.

Software programs that allow children to create, like an art or publishing suite designed specifically for kids, can boost creativity along with providing exposure to technology. Grade level skills can also be practiced and enhanced with math, reading, and spelling computer games. There are a number of kid-friendly websites that provide search engines, games, and interaction opportunities.

Computer education for children should also include writing and creative writing activities. First graders are beginning to familiarize themselves with the keyboard and can write short letters or emails. By second and third grade, children can use word processor programs or writing software designed for children to write and publish their own short stories and poems, as well as use email to write to relatives.

Board Games and Their Benefits for Families

2011-12-23T14:11:00.000-08:00

Board Games have long been known to have educational benefits, hence the use of them in many classrooms around the world. But what are the main benefits and do they apply to playing in the home and family setting?

Let's look at a four of the main educational benefits of board games and how they can encouraged in family game time.

Educational Games For Toddlers

The basic skill required to play is co-operation. Even competitive games actually teach co-operation as well. This is because of the fact that board games generally require more interaction than video games and movie watching. This interaction is in the forms such as talking, taking turns and even waiting for others. There is quite different from a video game, where play just keep on going, no matter what as happened to your opponent, you never stop and wait for them!

As stated above, co-operation is the basic skill board gaming teaches and it is from the co-operative interaction of playing a board game that many of the other educational benefits of playing board games arise.

The talking or conversation that occurs during game play enhances communication and families would do well to encourage children to talk about their gameplay. To explain why they moved, to voice concerns at other's moves and even to point out possible cheating!

Taking turns, and the waiting involved in this process, while another player takes their turn teaches both patience and respect for others. It seems a minor thing, but learning to do something as simple as making time for someone else to play their move, teaches children to be compassionate for others. To realize that the world does not revolve around them and that other people often miss out if one person rush in and vice versa. It also teaches them that sometime in life you simply have to wait and it helps to combat the impression, given by the mass media, that constant activity is the norm.

Yes, it does these things on a small scale and it only involves small time frames, but that is how teaching works. That is how the educational benefits of board game playing are passed on to children. Teachers know that most people only concentrate fully in small chunks, often somewhere between 5 and 10 minutes and for some people even less. So effective teaching often takes place in short bursts. Having to wait and observe for a few minutes between turns and then, when it is your turn, having a short period of decision making is a great way of educating and learning in small but powerful bursts.

Board Games then have at least four main educational benefits that are easily transferrable to home and family gameplay. Those four being; Co-operation, Communication, Patience and Respect.

If you want to create a web page using HTML - Hyper Text Markup Language, you will need the following two software:

Text Editor: It is used to write HTML tags according to the requirements of the web page. Windows Notepad is a suitable candidate for this purpose. You have to save the HTML document with html or htm extension. For example, type the name of your web page document as "first.html".

Web Browser: Web Browser is a software used to view web pages. Examples of a web browser are Internet Explorer, Mozilla Firefox and Google Chrome. Microsoft Windows users can view and test their web pages, in Internet Explorer.

I will discuss the Basic Structure of an HTML Document, in my next post.

Introduction To HTML

2011-12-20T19:55:00.000-08:00

HTML stands for Hypertext Markup Language. Hypertext refers to the text with Links. These links may point to sections of the same web page or any other web page within or outside the website.

HTML Definition

HTML is a language used to create and format web pages. HTML is used to define the structure and format of a web page. HTML will place and format the contents like text, pictures, audio or video data in your web pages. Moreover,you can use Links to connect the related web pages in the form of a website.

Who Invented HTML?

HTML was developed by Tim Berners Lee in 1989.

TAGS and Elements

HTML uses commands called TAGS to create and format different elements
and contents of a web page. HTML tags are enclosed within angle brackets <>. For example <b> tag is used to format some text as bold text.
Normally, tags work in pairs as shown in the example below.

<b> This is bold text. </b>
The output of the above HTML command or tag will be as show next in blue:
This is bold text.

The <b> tag is called Opening Tag or start tag, whereas </b>
tag is called Closing Tag or end tag. most of the tags use both opening
and closing tags. A few tags like <br> tag (used for line break)
and <hr> tag (used for horizontal rule, that is, a horizontal line)
is used as single tags. They do not need closing tags. Such tags are also called
Empty Tags.
Every HTML Tag is related to some HTML element. For example, <TABLE>
tag is used to create a table HTML element. Each HTML documents consists of
HTML elements.

Attributes

An attribute is an additional information to implement a tag. It gives some
extra information to enhance the format of the element related to that tag. For
example, <TABLE> tag is used to create a table in a web page. If we use a
<TABLE> tag without a BORDER attribute, table element will have no
border. If we use BORDER="1" in opening <TABLE> tag,
table will be created with a border. BORDER is the attribute to
specify border width for a table and 1 is the value assigned to BORDER
attribute, as shown below:

<TABLE BORDER="1">

.

.

.

</TABLE>
Note: Attribute is used in Opening Tag always like BORDER="1".
Note: No attribute in Closing Tag.

Grief & Loss - Children Losing Parents

2011-12-18T23:24:00.000-08:00

According to Weenolsen (1988) loss can be characterized as anything that destroys some aspect of life or self. According to Worden (2002) grief can be characterized as the experience of someone who has lost an important relationship or even an attachment to another person. These concepts can be directly related to the loss of a parent. Losing a parent can be extraordinarily difficult due to the loss of support and characteristics which identify the position and role of a parent as being very special (Despelder & Strickland, 2005). The grieving processes can mean different changes for those within different roles. Older adults who lose their parents do not process or grieve as a child who has lost their parent. I feel that both of these specific roles and experiences are of greatest importance. Issues of culture also maintain consistent changes across societies in how one works through or expresses the loss of their loved ones. Support for children and adults is a very important part of the grieving process and should be connected to characteristics of who children and adults are within their roles and how they respond to such loss.

Due to modern technology only about 4 % of children experience the loss of a parent before the age of 18 yrs (Archer, 1999). In comparison, in the late 1700's to early 1800's many children were without parents, making life much more difficult for children (Fox & Quitt, 1980). One cannot discuss the loss of a parent to a child without discussing segments of attachment and other developmental theory. Attachment according to Davies (2004) is a special emotional relationship between two people. According to Archer (1999), Bowlby indicated that children are able to grieve and mourn when attachment processes become solidified around the age of six months to one year of age (Archer, 1999; Worden, 2002).

Educational Games For Toddlers

According to Weenolsen (1988) reactions related to grief and mourning begin within the early stages of infancy and learning when the child begins to understand their control over the environment, slowly gaining differentiation and losing their dependency. The mourning of this loss in dependency through the child's ability to gain control over their environment does manifest crying and seeking out behaviors that train the child to respond in this manner to gain access to their care giver (Weenolson, 1988). This instinctive response will be further utilized during future separations and loss (Weenolsen, 1988). Rando (1988) also claims that infants mourn when their nurturance is withdrawn and the mother (primarily) must assist in re-establishing the nurturing connection, thus reducing separation. These theoretical positions seem to be consistent with Attachment Theory in that it is the separation that initiates reactions. Furthermore, one could not understand or comprehend separation if one did not realize their own ability in controlling environmental circumstances in order to meet ones needs. It seems apparent that regarding reaction or understanding the meaning of death by children one would require sufficient cognitive ability.

The loss of a parent and the response is also due to what Bowlby characterizes as the loss of the child's "safe haven" or "secure base" to explore the world (Davies, 2004). One could hypothesize that this disruption of security would effect a child's exploration during toddler development, and at times hinder needed environmental interactions. According to Archer (1999) reactions by children during the mourning process due to the loss of a parent include; pining, preoccupation, yearning, seeking or calling. According to Littlewood (1992), Bowlby clarified that this reaction to loss as instinctive; and the seeking of the lost object (the parent) although fruitless, it is performed anyway. Although many reactions due to many types of circumstances are chosen by children as a response to emotional distress; these responses are considered specific to the loss of a parent (Archer, 1999). Furthermore, many of the emotional disturbances can bring with them depressive and anxious symptomatology; as well as sleep disturbances (Archer, 1999).

Children age 2 to 5 yrs. of age seem to ask many questions regarding the parental loss (Rando, 1988) They may display regressive behaviors, obsession over questions and circumstances, and may display anxiety and anger toward the deceased (Rando, 1988). There may also lay feelings of guilt and responsibility for the loss of the parental figure (Despelder & Strickland, 2005). Some of these reactions were clearly represented in my four year old son Jonathan who lost his grandmother this past year; he seemed to obsess over the funeral and what he had witnessed.

Ages 8 to 12 yrs. may feel helpless and experience reawakened feelings of childlessness (Rando, 1988). Children at this age may seek to repress such feelings, putting them at risk for complicated grief reactions (Rando, 1988). This would be consistent with Eric Erickson's stages of psycho-social development in regards to the stage of "industry vs. inferiority." According to Longress (2000) and Anderson, Carter & Lowe (1999) there is a push for the child to become "industrious" and confident during this stage of development. It seems clear that admitting ones childish and helpless feelings would be difficult during this period.

According to Worden (2002) when a death of a parent occurs in childhood or adolescents the child may not mourn effectively and this may create problems with depression and inabilities to maintain close relationships with others (p.159). According to Rando (1988) depression, denial and anger are feelings that seek to counter act the helplessness, dependency and powerlessness that adolescents are feeling. This response seems consistent when examining Erickson's psycho-social stages (Berger, 2001; Longress, 2000; Anderson et. al., 1999). During adolescents there is a pursuit to find ones "identity", and the parent is a role modeling figure who can assist with guiding and encouraging this process (Berger, 2001; Longress, 2000; Anderson et. al., 1999). It is understandable how an adolescent may feel powerless, helpless, dependent, and even angry due to the death of their parental figure.

In regards to meaning, Fiorini & Mullen ( Article ) clarify that it is very important to characterize the meanings of grief and loss through a developmental lens. According to Worden (2002), Murry Bowen clarified that one must understand the role and position of the dying parent within the family system, and the level of adaptive abilities of family members during and after the loss of a parent. I feel, as a social worker it is important with this information to better understand what this systemic loss means to the developing child within the family system. To many children the loss of a parent means a loss of stability, security, nurturing, and affection (Despelder & Strickland, 2005). According to Worden (2002) there are needed cognitive processes and concepts that must be developed before grief can be fully understood by children. The factors are as follows;

1. Understanding time; and what forever means

2. Transformation process

3. Irreversibility concept

4. Causation

5. Concrete Operations

According to Worden (2002)

Figure 1.1

According to Archer (2002) children before the age of 5yrs. believe that death is reversible. Many young children up to this point maintain a figurative representation within their minds of the lost parent and do not completely understand the permanency of the circumstance until cognitive maturation takes place (Despelder & Strickland, 2005; Rando, 1988). This would validate findings by Piaget in regards to object permanence and development of the cognitive processes of children (Berger, 2001). According to Archer (2002), Speece and Brent indicated that children from the age of 5 to 7yrs. of age begin to understand the irreversibility of death. Furthermore, according to Archer (2002) children less than 7 to 8 yrs. of age however, represented a lack of understanding regarding the word "death." This is consistent with Piaget according to Archer (2002) and Berger (2001), that in order to understand such a concept as death and irreversibility, ones conceptual thought must be sufficiently developed.

Up to the age of 9 yrs. of age however, most children attribute the death of their parent to outside forces, such as God and other (Carey, 1985). According to Rando (1988) although children 8 to 12 yrs. of age may have a more clear perception of what death is and understand the irreversibility of the process, they may also refuse to accept it.

Adolescent understanding and meaning regarding the death of a parent can be characterized as one of frightening shock and in-depth spiritual examinations. The adolescent is capable of these processes due to what Piaget termed the Formal Operating Stage of development (Longress, 2000; Berger, 2001). A questioning of spirituality and ones mortality can also be associated with Erickson's stages of development in regards to adolescents finding and understanding their social and human identities within this stage (Longress, 2000; Berger, 2001; Anderson et. al., 1999).

According to Littlewood (1992) it was indicated by studies from Anderson (1949), Bunch (1971) and Birtchnell (1975) that adults who lose parents react with tendencies to

have increases regarding:

1. Suicide ideation

2. Rates of suicide

3. Rates of clinical depression

According to Littlewood (1992)

Figure 1.2

Reactions and feelings related to the loss of a parent as an adult differ according to ones age (Rando, 1988). Adults in their twenties and thirties continue to view their parents as significant support structures, and losing them my feel as if one has been robbed. Feelings of childishness and regression is common and should not be repressed or ignored (Rando, 1988). One may find themselves utilizing their attachments to others such as children, friends, etc. in order to work through the grieving process (Rando, 1988). According to Rando (1988) it should be understood that the emotional nature of the relationship between the adult and parent will effect how the adult works through the grieving process. With this information one could hypothesize that the more an adult is undifferentiated in their identity in regards to the emotional parental relationship; the more difficulty they will have with separation (McGoldrick, 1998). This also would be consistent with Attachment Theory and the reactions associated with separation in regards to utilizing other constructed attachments in the absence of the parental primary (Davies, 2004). According to Littlewood (1992) a study by Sanders (1980) regarding grieving scales indicated that parents who lose their parents reacted high in two areas:

1. Increased death anxiety

2. Loss of control

According to Littlewood (1992)

Figure 1.3

According to Littlewood (1992) the increased anxiety is the result of the adult child feeling as if the are next in the generational line to experience death. The loss of control represents the loss of an important and unique relationship between the adult child and parent that sustained significant support features for the child (Littlewood, 1992; Despelder, 2005). From a gender prospective, it is believed according to Porter & Stone (1995) woman seem to indicate greater problems within the realm of relationships after a significant loss; men report greater work related problems through out the grieving process.

The meaning of losing our parents can different for many adults depending on the importance of the adult child / parent relationship (Rando, 1988). The parent has been the most significant and most influential force within the lives of their children; to lose this special relationship, is to lose a great deal in regards to support, the past and childhood connections, and an interpretation of circumstances within the world (Rando, 1988). These changes according to Rando (1988) & Despelder (2005) may place an adult in the position and process of no longer viewing themselves as a child; thus called the "developmental push." According to Despelder (2005), Rando (1988) & Littlewood (1992), the loss of the mother is usually more severe for adults than the loss of a father. This information is based on two primary factors:

1. The mother is usually the most nurturing

2. The mother is usually the last parent to experience death

Despelder (2005), Rando (1988) & Littlewood (1992) Figure 1.4

Losing a parent within adulthood also means "not having a home" to go back to which can leave a person feeling alone and frightened (Rando, 1988).

It seems clear that the death of a parent and its meaning can be commonly stated as a process that will force the adult child to redefine themselves, their roles, and expectations for their lives and the lives of their family of procreation.

According to Irish, Lundquist and Nelsen (1993) how cultures react and define meaning of death and loss of a parent varies. When examining the behaviors and perceptional meanings of death in various societies of the world, differences are evident between collectivistic / naturalistic cultures and individualistic / modernized cultures (Kalish, 1977). One primary difference that can be identified is the blame and reasons for ones death across cultures. Within modern societies death can be attributed to internal body failures due to poor nutrition and health maintenance (Kalish, 1977). Within our modernized society we may blame the person or parent for creating internal processes that led to their own deaths; like smoking, poor eating habits, etc. (Kalish, 1977). Within other cultures, especially isolated societies external agents would be to blame for the death of a parent, such as evil spirits or magic (Kalish, 1977).

Other grief differences across cultures include examples of muted grief, excessive grief, somatization, and excessive grief (Irish et. al., 1993). According to Irish et. al., (1993) in Bali if one does not remain emotionally calm and mute their grief process after the death of a parent or any loved one, sorcery and magic may place a person vulnerable to harm. Irish et. al., (1993) indicates Wikan's (1988) investigation of Egyptian culture expressed excessive grief through constant suffering and bereavement over an extended period of time. According to Oltjenbruns (1998) a study comparing scores upon the Grief Experience Inventory between Mexican students and Anglo students expressed that Mexican student's results expressed much higher somatization scores, thus indicating that Mexican culture seems to express greater amounts of somatization due to loss. Violent grief and rage seem to be expressed across most cultures; the initiation of this rage or violence seems to be connected to external circumstances; such as other cultures or other people who caused the death of a loved one (Irish et. al., 1993; Kalish, 1977; Archer, 1999).

According to Rando (1977) if children do not resolve their grief; complications can develop, such as; psychosomatic illness, psychological disturbances, adjustment disorders and behavior issues (p. 1999). One strategy according to Rando (1977) is for a therapist to facilitate the withdrawal of attachment from the deceased and make attempts to redirect the emotional energies in another primary figure in the child's life. This process of course would include identifying primary support structures that assist in sustaining the child's emotional, psychological, and social well being (Littlewood, 1992). Support structures could be identified as either formal or informal processes (Littlewood, 1992). It seems to be important to utilize professional support to assist a child as well as family before, during and after the death of a significant loved one, such as a parent (Littlewood, 1992). During these processes it would also be useful according to Littlewood (1992) to utilize informal supports; such as family members and others to assist with reducing psychological and emotional distress within the child or adults. It would seem that a therapist would be obligated to assess the roles, expectations and culture of the family and children before initiating any informal or formal interventions.

According to Rando (1977) children may at times act as if they are playing death games or acting out the funeral activities; however this is their way of coping and taking a break from their grief. Because children also have difficulty expressing their feelings, thoughts, and memories of the lost parent, it is important that a therapist assist with facilitating emotional expression (Rando, 1977; Despelder, 2005). Ways of gaining a child's attention and assisting them with expressing this emotion is to utilize book readings by authors who have written stories that relate to childhood grief (Despelder, 2005). Other strategies a therapist could utilize is art therapy and support group interventions to express emotional and psychological processes (Despelder, 2005).

Processes and supports for adults who have lost their parents and others are important processes that will assist adults through the grieving process. When assisting adults in coping with the loss of their parent it is important to understand that there are gender differences in coping with loss (Archer, 1999). According to Archer (1999) women tend to utilize greater emotional expression and emotional components to cope with the loss of a parent. Men it is believed, utilize problem solving strategies throughout their grieving process (Archer, 1999). According to Gallagher, Lovett, Hanley-Dunn, & Thompson (1989) woman seem to utilize cognitive process in order to work through the grieving process, where as men were indicated as utilizing "keeping busy" types of activities. One could hypothesize that a therapist would have to develop therapeutic interventions that would utilize these innate way's of coping according to one's layered identity, such as with gender. With this knowledge, Worden (2002) clarifies that a counselor should primarily seek goals that facilitate acknowledging the reality of the loss, to help the person with expressed and latent affect, to assist with problems related to readjustment and to assist the person with remembering the deceased while feeling good about moving on within their own lives (p. 52).

In concluding, one must understand that with the loss of a parent, the roles and expectations of those left behind will have dramatic effect upon them and the ways in which a social workers must intervene. It becomes apparent that through out the grieving process for children or adults primary considerations must be applied. Gaining better understandings of child and adult reactions and meanings of parental loss, examining the information through a cultural and gender perspective and utilizing coping and support processes to assist the bereaved is of great importance.

Advantages and Disadvantages of Mesh Topology

2011-12-04T05:30:00.000-08:00

Mesh Topology

In a mesh topology, every device on the network is physically connected to every other device on the network. Therefore, data can be sent on several possible paths from source computer to destination computer. Mesh topology is more reliable with better performance. It is mostly used in wide area networks where reliability is important.

Advantages of Mesh Network Topology

1. Since, there are many links to transfer data, Mesh topology gets rid of the traffic problem. Data may be transferred through different links.
2. If one link becomes unusable, it does not disturb the whole system. Other links can be used for communication.
3. Since each node has physical connection with other nodes, therefore, one node can transfer data to many nodes at the same time.

Disadvantages of Mesh Network Topology

1. It is very expensive due to implementation of multiple links for each node.
2. It is difficult to install and reconfigure.
3. Adding or removing a computer is difficult.

Advantages and Disadvantages of Tree Topology

2011-12-04T04:54:00.000-08:00

Tree Topology

Actually, a Tree topology is the combination of two topologies: bus and star topology. A tree topology combines the characteristics of bus and star topologies. It consists of groups of computer connected as star topology. These groups are then connected to a central communication medium (bus cable).

Advantages of Tree Network Topology

1. Many software and hardware vendors support tree topology.
2. It provides point-to-point wiring for individual groups.

Disadvantages of Tree Network Topology

1. If the main backbone line breaks, the entire tree network goes down.
2. It is more difficult to configure and maintain.
3. If any hub fails, related segment will be removed from the network.

Advantages and Disadvantages of Ring Network Topology

2011-12-04T04:20:00.000-08:00

Ring Topology

In Ring topology, each computer is connected to the next computer such that last computer is connected to the first. Every computer is connected to next computer in the ring. Each computer retransmits what it receives from the previous computer. Suppose, computer A needs to send data to computer D. Now the computer A sends data to computer B. As computer B is not the destination computer, so it will retransmit data to computer C. Finally, Computer C will transfer data to computer D, the destination computer. When a node sends a message, the message is processed by each computer in the ring. If a computer is not the destination node, it will pass the message to the next node, until the message arrives at its destination.

Advantages of Ring Network Topology

1. It is relatively less expensive than a star topology network.
2. In a Ring topology, every computer has an equal access to the network.
3. Performs better than a bus topology under heavy network load

Disadvantages of Ring Network Topology

1. Failure of one computer in the ring can affect the whole network.
2. It is difficult to find faults in a ring network topology.
3. Adding or removing computers will also affect the whole network since every computer is connected with previous and next computer.
4. Sending a message from one computer to another takes time according to the number of nodes between the two computers. Communication delay is directly proportional to number of nodes in the network.

Advantages and Disadvantages of Star Topology

2011-12-04T04:04:00.000-08:00

Star Topology

Star Topology is the most popular and widely used network topology in local area networks. In star topology, all computers are connected with a central device known as HUB or Switch. Now-a-days Hubs are often replaced by Fast Network Switches. The sender computer sends data to the hub. The hub sends it to the destination computer. So, all data communication is managed through HUB or Switch.
Note: The major difference between a Networking Hub and Networking Switch is that HUB sends data to all computers, and the destination computer will accept it while other computers will not. On the other hand, Switch sends data only to the destination computer. Therefore, switch can reduce network traffic and hence provides fast transmission speed.

Advantages of Star Network Topology

1. Easy Installation and maintenance

It is easy to maintain network. That is why it is so popular.

2. Adding or removing computers

Adding or removing computers can be done without disturbing the network. We connect the new computer with the HUB by means of a networking cable. One end of the cable (RJ 45 connector) is inserted in computer’s Network Interface Card and the other end (RJ 45 connector) is plugged into the HUB, and that’s it.

3. Fault Diagnosis

In a star network topology, finding faults is easy. If a computer is no more connected with your network, you can check its cable and connectors or network settings in its Operating system.

4. Network Reliability

Single computer failure will not disturb whole network, since all other computers are connected with separate links ( wires ) to HUB. Definitely, they will work fine.

5. Better performance

Star topology can prevents the passing of data through an excessive number of nodes. By using a Switch, at most, 3 devices and 2 links are involved in any communication between any two devices.
6. Device Isolation
Each device is separately connected to HUB or Switch and is isolated. This is why each device works independently.

Disadvantages of Star Network Topology

1. In star network topology, data communication depends on HUB. If central hub fails, then whole network fails.
2. Since each computer will be connected with HUB by means of a separate wire, star network topology needs more cable to connect computers.
3. It is more expensive due to more wires.

Bus Topology Advantages Disadvantages

2011-12-04T03:53:00.000-08:00

Bus Topology

Bus topology is the simplest network topology. In bus topology, all computers in network are connected to a common communication wire. This wire is called BUS. Terminators are used at both ends of wire.

Advantages of Bus Network Topology

1. It is very simple topology.
2. It is easy to use.
3. It needs small amount of wire for connecting computers.
4. It is less expensive due to small wire needed.
5. If one computer fails, it does not disturb the other computers in network. Other computers will continue to share information and other resources with other connected computers.

Disadvantages of Bus Network Topology

1. Only small number of computers can be connected in a bus network.
2. Network speed slows down as the number of computer increases in bus topology.
3. Finding a fault is difficult in bus topology.

Types Of Computer Networks

2011-11-24T20:02:00.000-08:00

Explain different types of computer networks:(LAN,WAN,MAN)

Main types of computer networks are:

1. LAN - Local-Area Network

2. WAN - Wide-Area Network

3. MAN - Metropolitan-Area Network

1)LAN (Local Area Network)

LAN stands for Local Area Network. It covers a small area. Most LANs are used to connect computers in a single building or group of near buildings. Hundreds or thousands of computers may be connected through LAN. LANs are used in office buildings, college or university campus etc. Local Area Networks can transfer data at a very high speed. Data transmission speeds of LAN are 1 to 100 megabits per second.

Examples:

Following are two examples of LAN:

LAN is used in a computer lab to connect computers. The students can share software, files and data in the lab.
In Internet cafe, many computers can be connected through LAN. These computers can share single connection of Internet.
Local Area Network can be used in an office to share common data and a network printer and any other software or hardware.
A local area network in a digital library can provide access to centralized collection of digital books for many readers using different computers in library building.

2)WAN (Wide Area Network)

WAN stands for wide area network. It covers a large area. WAN connects computers in different cities, countries and continents. So, Wide Area Networks are used to transfer data over very long distances across cities, countries or even in whole world. WANs are used to connect LANs and other types of networks together, so that users and computers in one location can communicate with users and computers in other locations.

Computers in WAN are often connected through leased lines telephone lines. They can also be connected through satellites. Transmission rate of WAN is 56 kbps to 45 Mbps. WAN is expensive than LAN. WAN is not as fast as LAN. There is a possibility of error in data transmission due to very long distance they cover. The largest WAN is the Internet. With the help of internet, we can send our data in any part of the world.

Examples of WAN

In air line ticketing system, many offices of an air line company can be joined together using WAN. A person can get a ticket from any office in the country.
A bank with many branches in different cities can connect its branches through WAN. The customer can use his account from any branch.

3)MAN (Metropolitan-Area Network)

A metropolitan area network (MAN) is a network that covers an area of the size of a city. So, a MAN is larger than a local area network but it is smaller than a WAN. A MAN is optimized for a larger geographical area than a LAN, ranging from several blocks of buildings to entire cities. MANs can use communications channels of moderate-to-high data transfer rates. It may use fiber Optic cable for fast speeds.

A MAN typically includes one or more LANs but cover a small area than WAN. A MAN often acts as a high-speed network.

Example:

Mobile phones systems often use MAN.
Many local ISPs manage MAN with the help of cable modems within a city.
Local cable TV networks also uses MAN technologies.

Computers Past and Present

2011-11-18T06:54:00.001-08:00

Vast amounts of folks use personal computers in their every day life all through the world. Throughout decades, the personal computer has evolved from a pretty pricey and slow device to today's highly smart machines with unbelievable processing power. The term 'computer' originally implied a person, who, under instructions from a mathematician, performed mechanical calculations. Mechanical calculating devices such as the abacus had been usually put to use to aid this procedure.Towards the end of the Middle Ages, mathematics and engineering in Europe received a big boost, therefore bringing about the invention of a number of mechanical calculating devices. The technology for clockwork was developed by the early 17th century. The period between the early 19th century and early 20th century saw the introduction of a variety of technologies which could be vital for the development of the digital computer later on. Examples are the punched card and the valve. Charles Babbage was the first individual to design a fully programmable laptop or computer as early as 1837. Nonetheless, he was not able to truly construct his personal computer as a result of a number of reasons.Analog personal computers were increasingly utilized in the very first half of the 20th century for quite a few scientific computing wants. Even so, they became obsolete after the development of the digital computer.The very first digital personal computer was the Atanasoff Berry Personal computer . It utilised a binary program of arithmetic, parallel processing, a separation of memory and computing functions. Binary math and electronic circuits - both of that are utilised in today's computers - were very first utilized in the Atanasoff Berry Personal computer.No single person was credited with the invention of personal computer, numerous think that Konrad Zuse and his Z1 machine was the first in a long line of innovations that gave us the laptop or computer of nowadays. Konrad Zuse was a German who was renowned for the creation of the very first freely programmable mechanical computing device in 1936. Zuse's Z1 was developed having a focus on 3 simple elements that are still necessary in today's calculators. Later, Konrad Zuse developed Z2 and the Z3. No single individual was credited with the invention of laptop or computer, numerous think that Konrad Zuse and his Z1 machine was the first in a lengthy line of innovations that gave us the personal computer of today. Konrad Zuse was a German who was famous for the creation of the very first freely programmable mechanical computing device in 1936. Zuse's Z1 was created with a focus on 3 basic elements which are still crucial in today's calculators. Later, Konrad Zuse developed Z2 plus the Z3.The first of the MARK series personal computers had been becoming built at Harvard. The MARK I began in 1944 and this pc was enormous filling in a room having a size of 55 feet lengthy by 8 feet high. The MARK I could perform a wide selection of calculations. It became a roaring success and was utilized by the US Navy. It was subsequently in service till 1959. The ENIAC personal computer was one of most crucial achievements in computing. It was commissioned during World War II and utilised by the US military. Vacuum tubes had been utilized by this laptop or computer as an alternative to electric motors and levers for fast calculations. Its speed was about thousand times faster than any other calculating device in the course of that time. This computer was enormous and had a total price of $500,000. The ENIAC was in operation till 1955.RAM or Random Access Memory was very first introduced in 1964. The first RAM was a metal detector plate positioned close to a vacuum tube which detected the difference in electrical charges. Throughout the 1950's, laptop or computer design was primarily valve driven. This was later replaced by transistor-driven style within the 1960's. Transistor-based computing devices were smaller, quicker and less expensive, and hence commercially viable. Integrated circuit technologies, adopted in the 1970's enabled laptop or computer production costs to hit a new low, so that even individuals could afford them. That was the birth of the personal personal computer, as it truly is known these days. IBM is known for making the very first individual pc widely cost-effective and available to the individuals. IBM 701 was the very first general purpose personal computer developed by IBM. The new pc language called FORTRAN was used in the new 701. Other IBM computing devices also followed like the 704. The IBM 7090 also was a big success and it dominated small business computing devices for the next 20 years. In the late 1970's and into 1980 IBM developed a personal laptop or computer identified as the PC. IBM has had a massive influence on the computers used currently. And then in 1984, the Apple Macintosh was released and Apple personal computers dominated the marketplace.With all the development of personal laptop or computer market in the early and mid 1980s, lots of businesses realized that GUI or Graphical User Interface was user friendly. This led to the growth and development of an operating system called Windows by Microsoft. The very first version was referred to as Windows 1.0 and later came Windows 2.0 and 3.0 editions. Microsoft is increasingly well-known right now.These days, pcs are very effective and more inexpensive than ever. They have practically infiltrated into every element of our lives. It's employed as a potent tool of communication and commerce.

Computer Viruses, Worms, and Trojan Horses Explained

2011-11-18T06:53:00.000-08:00

OverviewComputer viruses, worms, and Trojan horses are malicious pieces of software that can cause considerable damage to your computer hardware, software, and information stored in it. They can also slow down your PC, making it virtually unusable. This type of software falls into the category of malware (short for malicious software) since it isdesigned to harm or secretly access a computer system without the owner's informed consent. Computer virus hoaxes are also quite common, but harmless in nature.An often asked question, particularly from people relatively new to computers, is "Where do computer viruses come from?" The answer is simple. People write computer viruses. A person writes the code, tests it to ensure that it will spread properly, decides what the virus will do, and releases it. There are many psychological reasons why someone would do this, and these virus authors are often compared to vandals or arsonists.The Creeper Virus is generally accepted as the first computer virus. It was first detected on ARPANET, the forerunner of the Internet, in the early 1970's, infecting DEC PDP-10 computers running the TENEX operating system. Creeper gained access via the ARPANET and copied itself to the remote system where the message, "I'm the creeper, catch me if you can!" was displayed.Computer viruses, as we know them today, were first widely seen in the late 1980s, and they came into existence because of several factors. The first factor was the spread of personal computers (PCs). During the 1980s, the IBM PC (released in 1982) and the Apple Macintosh (released in 1984) became very popular, with widespread use in businesses, homes and college campuses.The second factor was the use of computer bulletin boards. Using a modem, people could dial up a bulletin board and download programs of all types. Games were extremely popular, and so were simple word processors, spreadsheets and other productivity software. Bulletin boards led to the precursor of the virus known as the Trojan horse.The third factor that led to the creation of viruses was the floppy disk. In the 1980s, programs were small, and you could fit the entire operating system (usually MS-DOS), a few programs and other files onto a floppy disk or two. Many computers did not have hard disks, so when you turned on your machine it would load the operating system andeverything else from the floppy disk. Virus authors took advantage of this to create the first self-replicating programs. Quite often these floppy disks were shared among computer users, allowing the virus to spread from one computer to another.VirusesA computer virus is a small piece of software that, like a human virus, is capable of replicating itself and spreading. In order to do this, a virus must be permitted to execute code and write to memory. For this reason, many viruses attach themselves to executable files (real programs), such as your favourite text editor program or other utility. If you launch the text editor program, the virus' code may be executed simultaneously, allowing it to replicate itself, and attachto other programs.An e-mail virus travels as an attachment to e-mail messages, and usually replicates itself by automatically mailing itself to dozens of people in your e-mail address book. Some e-mail viruses don't even require a double-click -- they launch when you view the infected message in the preview pane of your e-mail software. Being a computer professional with over 30 years experience in the software industry, I have seen a lot of bogus e-mail, so receiving the following message recently was not a surprise.Dear customer.The parcel was send your home address.And it will arrice within 7 bussness day.More information and the tracking number are attached in document below.Thank you.2011 DHL International GmbH. All rights reserverd.Of course, the e-mail also contained an attachment in the form of a ZIP file. Not only is the spelling bad, but the grammar is bad as well. And they claim to be DHL, a reputable company! My curiosity didn't get the better of me -- I decided not to open the attachment.One of the more famous e-mail viruses appeared in March, 1999 and was known as the Melissa Virus. Anti-virus software vendors refer to this virus as the Melissa macro or W97M_Melissa virus. It propagated itself in the form of an e-mail message containing an infected Microsoft Word 97 or Word 2000 document as an attachment. It was so powerful that it forced a number of large companies, including Microsoft, to completely turn off their e-mail systems until the virus could be contained.Virus HoaxesA computer virus hoax is a message warning the recipient of a non-existent computer virus threat. The message is usually a chain e-mail that tells the recipient to forward itto everyone they know.Most hoaxes are sensational in nature and easily identified by the fact that they indicate that the virus will do nearly impossible things, such as blow up the recipient's computer and set it on fire, or less sensationally, delete everything on the user's computer. Quite often the e-mail message claims to originate from a reputable company, such as Microsoft, giving the hoax more credibility.Virus hoaxes are usually harmless and accomplish nothing more than annoying people who identify it as a hoax and waste the time of people who forward the message. Nevertheless, a number of hoaxes have warned users that vital system files are viruses and encourage the user to delete the file, possibly damaging the system. Examples of this type include the jdbgmgr.exe virus hoax and the SULFNBK.EXE hoax.Some consider virus hoaxes to be a computer worm in and of themselves. They replicate by social engineering -- exploiting users' concern, ignorance, and reluctance to investigate before acting.The gullibility of novice computer users (my parents come to mind) convinced to delete files on the basis of hoaxes has been parodied in several popular jokes and songs. "Weird Al" Yankovic wrote a song called "Virus Alert" that makes fun of the exaggerated claims that are made in virus hoaxes, such as legally changing your name. Another parody is the honor system virus, which has been circulated under several different names including the Amish Computer Virus, the Blond Computer Virus, the Newfie Virus, and the Unix Computer Virus, is joke email claiming to be authored by the Amish who have no computers, programming skills or electricity to create viruses and thus ask you to delete your own hard drive contents manually after forwarding the message to your friends.The Tuxissa Virus is another parody of the virus hoax, based on the concept of the Melissa virus, but with its intent of installing Linux on the victim's computer without the owner's permission. The story says that it was spread via e-mail, contained in a message titled "Important Message About Windows Security". It was supposed to first spread the virus to other computers, then download a stripped-down version of Slackware and uncompress it onto the hard disk. The Windows Registry is finally deleted and the boot options changed. Then the virus removes itself when it reboots the computer at the end, with the user facing the Linux login prompt and all his Windows security problems solved for him.WormsA computer worm is a small piece of software that uses computer networks and security holes to replicate itself. Unlike computer viruses, worms do not need to attach themselves to programs, and don't require user intervention to spread. Worms are capable of replicating in great volumes, taking control of features on your computer that transport files or information. For instance, a worm called Code Red replicated itself more than 250,000 times in approximately nine hours on July 19, 2001, slowing down Internet traffic dramatically.The ILOVEYOU (also known as LoveLetter) worm successfully attacked millions of Windows computers in 2000 when it was sent as an attachment to an email message with the text "ILOVEYOU" in the subject line. The worm arrived in email in-boxes with the simple subject of "ILOVEYOU" and an attachment "LOVE-LETTER-FOR-YOU.TXT.vbs". The 'vbs' extension was hidden by default, leading unsuspecting users to think it was simply a text file (when in fact it was a Visual Basic script). Upon opening the attachment, the worm sent a copy of itself to everyone in the Windows Address Book and with the user's sender address. It also made a number of malicious changes to the user's system.Trojan HorsesA Trojan horse is a destructive computer program that masquerades as a valuable or entertaining tool. It claims to perform a desirable function, but in fact damages your computer system when it is run. A Trojan horse can be a virus or a remote control program. They are usually installed on a computer through an e-mail attachment.The term is derived from the Trojan Horse story in Greek mythology. In this story, the Greeks give a giant wooden horse to their enemy, the Trojans, apparently as a peace offering. But after the Trojans drag the horse inside their city walls, Greek soldiers sneak out of the horse's hollow belly and open the city gates, allowing their compatriots to pour in and capture Troy.Unlike viruses, Trojan horses do not replicate thdmselves but they can be just as destructive. One of the most crafty types of Trojan horse is a program that claims to rid a computer of viruses but instead introduces viruses onto the computer.Back Orifice is a famous example of a Trojan Horse, written to demonstrate the lack of security in Microsoft Windows 98. It was the brainchild of Sir Dystic, a member of the U.S. hacker organization CULT OF THE DEAD COW. It was designed for remote system administration, based on a client-server architecture, allowing a user to control a computer running Microsoft Windows from a remote location (much like Microsoft's Remote Desktop Connection software). This required two components to work -- a client application running on the attacker's computer and a server application running on the victim's computer. Once installed, the attacker can perform any number of tasks on the victim's computer, including transferring files to and from the victim's machine, crashing the computer, data theft, installation of software including malware, and keystroke logging for the purpose of acquiring user ids and passwords. Back Orifice 2000, the sequel to Back Orifice, was later released and could run on Windows NT machines.Another notable Trojan horse is called SubSeven. It was designed to attack computers running Microsoft Windows 95 and Windows 98. It is also similar in architecture to Back Orifice, but with a third component called a server editor (EditServer), which allowed the attacker to configure the infection. It provides many more options for attack than Back Orifice, however, allowing an attacker to issue virtually any command imaginable on a compromised system.Trojan horses are becoming more and more common. According to a survey conducted by BitDefender from January to June 2009, "Trojan-type malware is on the rise, accounting for 83-percent of the global malware detected in the world". This virus has a relationship with worms as it spreads with the help given by worms and travel across the Internet with them.Famous Computer Viruses And WormsThroughout history there have been a lot of computer viruses and worms created. Here is a list (in no particular order) of the most dangerous ones.Mellissa (1999) -- The Mellisa Virus caused damage estimated at between $300 and $600 million. This virus gained huge fame on March 26, 1999, with experts claiming that between 15 and 20 percent of all business PCs on the planet were infected.ILOVEYOU (2000) -- ILOVEYOU was first detected in the Philippines on May 4. In just one day it spread worldwide, with about 10 percent of all Internet users being affected by the worm, and caused $5.5 billion damage. When activated, the computer worm overwrote all files on the host, attaching a copy of itself to each file. In addition, the worm sent a copy of itself to everyone in the user's address book.Nimda (2001) -- Nimda used seemingly every possible method to spread, and was very effective at doing so. Nimda is notable for being one of the fastest spreading and most widespread viruses ever.Code Red (2001) -- Code Red targeted Internet Information Services (IIS) on Windows servers. It also launched denial of service (DoS) attacks.Creeper (1971) -- Creeper is generally accepted as the first ever computer virus.SQL Slammer (2003) -- This tiny virus infected servers running Microsoft's SQL Server Desktop Engine, and was very fast to spread.Elk Cloner (1982) -- Possibly the first personal computer virus, Elk Cloner infected the boot sector of Apple II floppies.The Morris Internet Worm (1988) -- The Morris worm infected Unix systems and is considered the grandfather of computer worms.Protecting Your ComputerYou can protect your computer from viruses with a few simple steps:Run a more secure operating system such as UNIX.If you are using an unsecured operated system, then purchase good anti-virus software that automatically scans e-mail attachments or other downloaded files. Make sure you scan for viruses at least once a week.You can eliminate almost all infection from traditional viruses by simply avoiding programs from unknown sources (such as the Internet). Download software from trusted sites only. Better yet, install only commercial software from a CD.Avoid opening attachments or clicking on links in e-mail from unknown senders. In particular, attachments that are executable files (i.e have an extension of EXE, COM,or VBS) can do all sorts of damage to your computer.Due to the destructive nature of viruses, it is important that you back up your data on a regular basis, particularly those files you can't afford to lose.Most up-to-date anti-virus programs, like McAfee VirusScan Plus, BitDefender, or CA Anti-Virus Plus, will guard against computer viruses and remove them should they be installed. Of course, they need to be updated with virus signature files to catch the latest variants that are released periodically. These signature files (sometimes called "definition files") can be obtained from the program vendor via the Internet.

Computer Errors - Hardware or Software

2011-11-18T03:07:00.001-08:00

Severe difficulties have severe causes, and identifying those causes is an essential part in the recovery practice. The good thing is, the number of causative factors is reasonably narrow. We have now determined four events that induce the majority substantial Computer system situations: computer system distress, computer data loss or corruption, inaccurate configurations, and program or equipment failure.(1) System distress. Personal computers have physical limits. Memory capacity, storage total capacity, and processing capabilities determine the most important of those limitations. Should you try to propel a Personal computer outside of its restrictions, you significantly add to the likelihood of encountering a critical difficulty. The computer system possibly will freeze, generate error messages, or freeze.Sometimes, system distress is a minor problem from which you'll recover merely by rebooting the PC. But now and again the stress becomes established, for example when there are too many software packages inside the Startup folder. In those situations, a small situation turns into a significant one that manifests itself each and every time you attempt to use your PC.(2) Data loss or corruption. The performance of one's computer is determined by the integrity of billions of binary digits, labelled bits, all of which are represented as electronic pulses on the magnetized platter inside the hard drive. If just one of these bits were to bite the dust, you could end up with software programs which don't perform, a computer system that does not start, hardware that doesn't respond, along with other substantial Personal computer predicaments. Does that scare you? It ought to, particularly when you consider the collection of possible risks.Data loss and corruption could possibly result from computer software glitches, user operating mistakes, computer system stress, and typical deterioration to the computer hardware. And then you will discover computer system malware, self-replicating bits of program code that infect Computers and wreak all sorts of destruction, and this includes data destruction. Infections, together with equally malevolent worms and Trojan horses, account for the most severe risk to your data because the injury should be able to spread so swiftly and quietly.Anti-virus software programs are a security staple. If you do not possess an anti-virus application program installed on your personal computer, download and install a free, streamlined program or buy a full-featured version immediately.(3) Incorrect settings. The computer's system configurations are just like driving directions: They have to be precise and comprehensive in order for the Computer system to take you where you need to go. Microsoft optimizes the OS' (operating system's) standard settings for the most suitable functionality, but these options change while you use and modify your personal machine and its contents. A application installation can lead to alterations in the Windows Registry, for example, whereas a wish for bigger functioning efficiency may well encourage one to upgrade the BIOS (Basic Input/Output System) settings manually.The aim of changing any options is increased overall performance. Often times though, that may not necessarily come about. Inaccurate configurations could certainly prevent you from starting a favorite software program, accessing the network or the Internet, or even starting up your computer. The cure is straightforward: Restore the controls to a working configuration. That's much easier said than done, however, especially should you not know which options was the cause of the issue.(4) Computer software and hardware malfunction. All of your Computers devices have essential roles to play. You can't expect to obtain optimum functionality from a computer hobbled by hardware and software failures.Software commonly fails as a result of coding flaws or inappropriate installment. Hardware components fail from typical deterioration or perhaps some form of compatibility mismatch with the remainder of the computer system. What ever the cause of the software or computer hardware failure, you need to definitely determine the failure and repair it if you would like your personal machine to operate as it should. Look out for the indicator symptoms, notably unresponsive hardware devices as well as error messages indicating that your software is not working properly.Crash ManagementAfter identifying that you may have a serious System problem on your hands, you should limit the destruction and make repairs. Thats usually where circumstances might get tricky, as few personal computer problems have distinct conditions and clear remedies. To help you out in your endeavor, we formulated a step-by-step tool to guide you with the operation of getting the computer back to normal.- Assess your situation. Exactly what occurred? That is what you will need to figure out. Start out by identifying the signs that exposed the presence of a problem. Was it an error message? If that's the case, jot it down word for word. Did your computer freeze up or just crash? If that's the case, make a note of what you were engaging in at the time the personal computer ceased working. The greater detail you are able to supply here, the better.Substantial problems which crop up when you remove a program from the Personal computer may be as a result of errors which happened during the un-install. You may be able to improve the situation through reinstalling the software followed by applying Vista's Uninstall Or Change A Program utility to uninstall the program once again.While you're at it, take the time to recall all the recent system adjustments. The addition of new program or hardware, the removal of old software programs or computer hardware, and modifications to system controls might cause a number of PC issues.- Treat the conspicuous. Attempting a significant repair to your computer with out first checking for unplugged cords, loose cable connections, along with other obvious problem areas is similar to scheduling a lobotomy to cure a headache with out first taking two aspirin to find out whether or not that relieves the pain. Always, always, always try the free and easy remedy previous to proceeding with one that's pricey and difficult.- Give it the reboot. One more thing it's best to do in reaction to a PC issue is reboot the computer. Or if the personal computer didn't start the first time around, you need to make an effort to boot the computer again. The way the Computer reacts to this particular attempt reveals a lot relating to the magnitude of this situation. In case the PC starts the way it should, you may be coping with a small problem. If the personal computer fails to boot or if it boots but does not run the way it should, you most likely have a serious issue.In case the PC does not start at all, you have two choices for gaining access to computer data. You can either start laptop computer in Safe Mode or boot the computer by using a bootable diskette.- Look over the guide. The typical users guide has a troubleshooting section that identifies frequent conditions and provides appropriate remedies. A similarly worthwhile resource for trouble shooting help is the product's Frequently asked questions, which often you should be able to search for on the net at the computer hardware manufacturer or software application developer's Web page.Even if these resources do not include a solution to your particular situation, some may give you guidance that might target your troubleshooting attempts in the proper direction.- Exterminate infections. Trojans may be one of the most insidious issues since they continue to replicate until you get rid of them from the personal computer. Discovering them thus remains a top top priority whenever trouble shooting your Personal computer. You'll need a little help accomplishing that, however, as numerous malware are meant to operate underneath the radar until after they cause significant damage. We would suggest running an up-to-date antivirus tool to scan the contents of your Computers many storage hard disks for the presence of harmful program code.The System Configuration Utility permits you to modify system configurations easily and quickly. Give it a try before making wholesale alterations in the BIOS (Basic Input/Output System) or Registry.- Fix computer software. Software-related issues fall into four categories: those you can easily address by reinstalling a program, those you can actually resolve by deleting a software program, those you can actually remedy by updating a software program, and those it is possible to resolve by accurately interpreting the contents of an error message.The problems that center around the installation or un-installation of software applications will be the ones easiest to spot because they traditionally come about shortly after you install or uninstall the offending program. Your best recourse in these conditions is to remove or re-install the software program from the computer (whichever is appropriate) and make a second attempt at the installation of or removing it. If that fails, you may want to update your personal computer's older software applications, most of which could possibly clash with the newest software program additions to your machine.Perhaps, probably the most difficult software-related issues are those that entail error messages. Not merely must you be capable of translate the contents of these types of messages but you also must discover how to respond to precisely what the messages are trying to tell you.- Fix hardware. A hardware component that gums up your system is either shot, improperly installed, or not communicating with the rest of your Computer. You have got the enjoyment of finding out which of these is the situation and just how to fix it.Begin by centering your attention around the components you most recently installed and then update the device drivers for the older computer hardware components within the system.- Clear out your startup. Part of the Windows startup routine involves starting each of the applications found in the Startup folder. A number of these software programs run in the background, so you might not even know they are running. Your Computer knows, however, and the extra load of those software programs could possibly have it huffing and puffing before you start any applications of your own.- Update system settings. Under normal conditions, we would most likely hesitate to advise making adjustments to system settings, however, if your personal machine suffers from a serious setback and none of the preceding procedures can correct the matter, then it's time to take extraordinary measures. The initial place to start is with the System Configuration Utility, a trouble shooting resource which will automates the process of pinpointing and solving problems with system files.If that does not work, you might want to switch your consideration to the Registry and BIOS settings. These advanced adjustments control your system's startup process and also play a substantial role in just about everything else your personal machine does.- Think about formatting the hard disk. For a lot of computer users, "format" is usually a daunting concept. Nonetheless, periodically this particular DOS command could turn out really helpful. As an example, you should think of reformatting your hard drive and starting over should the MBR (master boot record; a hard drive marker that helps the PC to find information within the drive) is need to be fixed or if a trojan has decimated a great deal of your data on the drive.Reformatting a disc drive effectively strips it of all data as well as prepares it to accept fresh information. The simplest way to reformat the disc drive is with the FORMAT command.- Ask for Help The last step involves seeking help from an outside resource. The very best assistance will probably come from your PC manufacturer, nevertheless, you might choose to speak to the appropriate hardware designer or software program developer if you're able to trace your predicament to a particular element of your PC.In any case, you might want to possess the names, versions, and serial numbers belonging to the troublesome products readily available when you make the phone call. Additionally you need to be prepared to read an account of the troubleshooting steps you've undertaken to date. This makes it easier for the assistance technician to provide the support you'll need. Furthermore, you should expect to pay a fee for the help you obtain as a number of software application designers and computer hardware producers now bill for phone-based technical guidance.

About two hundred years before, the word "computer" started to appear in the dictionary. Some people even didn't know what is a computer. However, most of the people today not just knowing what is a computer, but understand how to use a computer. Therefore, computer become more and more popular and important to our society. We can use computer everywhere and they are very useful and helpful to our life. The speed and accuracy of computer made people felt confident and reliable. Therefore, many important information or data are saved in the computer. Such as your diary, the financial situation of a oil company or some secret intelligence of the military department. A lot of important information can be found in the memory of computer. So, people may ask a question: Can we make sure that the information in the computer is safe and nobody can steal it from the memory of the computer? Physical hazard is one of the causes of destroying the data in the computer. For example, send a flood of coffee toward a personal computer. The hard disk of the computer could be endangered by the flood of coffee. Besides, human caretaker of computer system can cause as much as harm as any physical hazard. For example, a cashier in a bank can transfer some money from one of his customer's account to his own account. Nonetheless, the most dangerous thief are not those who work with computer every day, but youthful amateurs who experiment at night --- the hackers. The term "hacker "may have originated at M.I.T. as students' jargon for classmates who labored nights in the computer lab. In the beginning, hackers are not so dangerous at all. They just stole computer time from the university. However, in the early 1980s, hackers became a group of criminals who steal information from other peoples' computer. For preventing the hackers and other criminals, people need to set up a good security system to protect the data in the computer. The most important thing is that we cannot allow those hackers and criminals entering our computers. It means that we need to design a lock to lock up all our data or using identification to verify the identity of someone seeking access to our computers. The most common method to lock up the data is using a password system. Passwords are a multi-user computer system's usual first line of defense against hackers. We can use a combination of alphabetic and number characters to form our own password. The longer the password, the more possibilities a hacker's password-guessing program must work through. However it is difficult to remember a very long passwords. So people will try to write the password down and it may immediately make it a security risk. Furthermore, a high speed password-guessing program can find out a password easily. Therefore, it is not enough for a computer that just have a password system to protect its data and memory. Besides password system, a computer company may consider about the security of its information centre. In the past, people used locks and keys to limit access to secure areas. However, keys can be stolen or copied easily. Therefore, card-key are designed to prevent the situation above. Three types of card-keys are commonly used by banks, computer centers and government departments. Each of this card-keys can employ an identifying number or password that is encoded in the card itself, and all are produced by techniques beyond the reach of the average computer criminals. One of the three card-key is called watermark magnetic. It was inspired by the watermarks on paper currency.The card's magnetic strip have a 12-digit number code and it cannot be copied. It can store about two thousand bits in the magnetic strip. The other two cards have the capability of storing thousands of times of data in the magnetic strip. They are optical memory cards (OMCs) and Smart cards. Both of them are always used in the security system of computers. However, it is not enough for just using password system and card-keys to protect the memory in the computer. A computer system also need to have a restricting program to verify the identity of the users. Generally, identity can be established by something a person knows, such as a password or something a person has, such as a card-key. However, people are often forget their passwords or lose their keys. A third method must be used.It is using something a person has --- physical trait of a human being. We can use a new technology called biometric device to identify the person who wants to use your computer. Biometric devices are instrument that perform mathematical analyses of biological characteristics. For example, voices, fingerprint and geometry of the hand can be used for identification. Nowadays, many computer centers, bank vaults, military installations and other sensitive areas have considered to use biometric security system. It is because the rate of mistaken acceptance of outsiders and the rejection of authorized insiders is extremely low. Individuality of vocal signature is one kind of biometric security system. The main point of this system is voice verification. The voice verifier described here is a developmental system at American Telephone and Telegraph. Only one thing that people need to do is repeating a particular phrase several times. The computer would sample, digitize and store what you said. After that, it will built up a voice signature and make allowances for an individual's characteristic variations. The theory of voice verification is very simple. It is using the characteristics of a voice: its acoustic strength. To isolate personal characteristics within these fluctuations, the computer breaks the sound into its component frequencies and analyzes how they are distributed. If someone wants to steal some information from your computer, the person needs to have a same voice as you and it is impossible. Besides using voices for identification, we can use fingerprint to verify a person's identity because no two fingerprints are exactly alike. In a fingerprint verification system, the user places one finger on a glass plate; light flashes inside the machine, reflects off the fingerprint and is picked up by an optical scanner. The scanner transmits the information to the computer for analysis. After that, security experts can verify the identity of that person by those information. Finally, the last biometric security system is the geometry of the hand. In that system, the computer system uses a sophisticated scanning device to record the measurements of each person's hand. With an overhead light shining down on the hand, a sensor underneath the plate scans the fingers through the glass slots, recording light intensity from the fingertips to the webbing where the fingers join the palm. After passing the investigation of the computer, people can use the computer or retrieve data from the computer. Although a lot of security system have invented in our world, they are useless if people always think that stealing information is not a serious crime. Therefore, people need to pay more attention on computer crime and fight against those hackers, instead of using a lot of computer security systems to protect the computer. Why do we need to protect our computers ? It is a question which people always ask in 18th century. However, every person knows the importance and useful of a computer security system. In 19th century, computer become more and more important and helpful. You can input a large amount of information or data in a small memory chip of a personal computer. The hard disk of a computer system is liked a bank. It contained a lot of costly material. Such as your diary, the financial situation of a trading company or some secret military information. Therefore, it just like hire some security guards to protect the bank. A computer security system can use to prevent the outflow of the information in the national defense industry or the personal diary in your computer. Nevertheless, there is the price that one might expect to pay for the tool of security: equipment ranging from locks on doors to computerized gate-keepers that stand watch against hackers, special software that prevents employees to steal the data from the company's computer. The bill can range from hundreds of dollars to many millions, depending on the degree of assurance sought. Although it needs to spend a lot of money to create a computer security system, it worth to make it. It is because the data in a computer can be easily erased or destroyed by a lot of kind of hazards. For example, a power supply problem or a fire accident can destroy all the data in a computer company. In 1987, a computer centre inside the Pentagon, the US military's sprawling head quarters near Washington, DC., a 300-Watt light bulb once was left burning inside a vault where computer tapes were stored. After a time, the bulb had generated so much heat that the ceiling began to smelt. When the door was opened, air rushing into the room brought the fire to life. Before the flames could be extinguished, they had spread consume three computer systems worth a total of $6.3 million. Besides those accidental hazards, human is a great cause of the outflows of data from the computer. There have two kind of people can go in the security system and steal the data from it. One is those trusted employee who is designed to let in the computer system, such as programmers, operators or managers. Another kind is those youth amateurs who experiment at night ----the hackers. Let's talk about those trusted workers. They are the groups who can easily become a criminal directly or indirectly. They may steal the information in the system and sell it to someone else for a great profit. In another hand, they may be bribed by someone who want to steal the data. It is because it may cost a criminal far less in time and money to bride a disloyal employee to crack the security system. Beside those disloyal workers, hacker is also very dangerous. The term "hacker" is originated at M.I.T. as students' jargon for classmates who doing computer lab in the night. In the beginning, hackers are not so dangerous at all. They just stole some hints for the test in the university. However, in early 1980s, hacker became a group of criminal who steal information from other commercial companies or government departments. What can we use to protect the computer ? We have talked about the reasons of the use of computer security system. But what kind of tools can we use to protect the computer. The most common one is a password system. Password are a multi-user computer system's which usual used for the first line of defense against intrusion. A password may be any combination of alphabetic and numeric characters, to maximum lengths set by the e particular system. Most system can accommodate passwords up to 40 characters. However, a long passwords can be easily forget. So, people may write it down and it immediately make a security risk. Some people may use their first name or a significant word. With a dictionary of 2000 common names, for instance, a experienced hacker can crack it within ten minutes. Besides the password system, card-keys are also commonly used. Each kind of card-keys can employ an identifying number or password that is encoded in the card itself, and all are produced by techniques beyond the reach of the average computer criminal. Three types of card usually used. They are magnetic watermark, Optical memory card and Smart card. However, both of the tools can be easily knew or stole by other people. Password are often forgotten by the users and card-key can be copied or stolen. Therefore, we need to have a higher level of computer security system. Biometric device is the one which have a safer protection for the computer. It can reduce the probability of the mistaken acceptance of outsider to extremely low. Biometric devices are instrument that perform mathematical analyses of biological characteristics. However, the time required to pass the system should not be too long. Also, it should not give inconvenience to the user. For example, the system require people to remove their shoes and socks for footprint verification. Individuality of vocal signature is one kind of biometry security system. They are still in the experimental stage, reliable computer systems for voice verification would be useful for both on-site and remote user identification. The voice verifier described here is invented by the developmental system at American Telephone and Telegraph. Enrollment would require the user to repeat a particular phrase several times. The computer would sample, digitize and store each reading of the phrase and then, from the data, build a voice signature that would make allowances for an individual's characteristic variations. Another biometric device is a device which can measuring the act of writing. The device included a biometric pen and a sensor pad. The pen can converts a signature into a set of three electrical signals by one pressure sensor and two acceleration sensors. The pressure sensor can change in the writer's downward pressure on the pen point. The two acceleration sensor can measure the vertical and horizontal movement. The third device which we want to talk about is a device which can scan the pattern in the eyes. This device is using an infrared beam which can scan the retina in a circular path. The detector in the eyepiece of the device can measure the intensity of the light as it is reflected from different points. Because blood vessels do not absorb and reflect the same quantities of infrared as the surrounding tissue, the eyepiece sensor records the vessels as an intricate dark pattern against a lighter background. The device samples light intensity at 320 points around the path of the scan, producing a digital profile of the vessel pattern. The enrollment can take as little as 30 seconds and verification can be even faster. Therefore, user can pass the system quickly and the system can reject those hackers accurately. The last device that we want to discuss is a device which can map the intricacies of a fingerprint. In the verification system, the user places one finger on a glass plate; light flashes inside the machine ,reflect off the fingerprint and is picked up by an optical scanner. The scanner transmits the information to the computer for analysis.

A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem.Conventionally a computer consists of some form of memory for data storage, at least one element that carries out arithmetic and logic operations, and a sequencing and control element that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from external source, and allow the results of operations to be sent out.A computer's processing unit executes series of instructions that make it read, manipulate and then store data. Conditional instructions change the sequence of instructions as a function of the current state of the machine or its environment.The first electronic computers were developed in the mid-20th century (1940-1945). Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1]Modern based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into mobile devices, mobile computers can be powered by small batteries. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.Machine codeIn most computers, individual instructions are stored as machine code with each instruction being given a unique number (its operation code or opcode for short). The command to add two numbers together would have one opcode, the command to multiply them would have a different opcode and so on. The simplest computers are able to perform any of a handful of different instructions; the more complex computers have several hundred to choose from--each with a unique numerical code. Since the computer's memory is able to store numbers, it can also store the instruction codes. This leads to the important fact that entire programs (which are just lists of these instructions) can be represented as lists of numbers and can themselves be manipulated inside the computer in the same way as numeric data. The fundamental concept of storing programs in the computer's memory alongside the data they operate on is the crux of the von Neumann, or stored program, architecture. In some cases, a computer might store some or all of its program in memory that is kept separate from the data it operates on. This is called the Harvard architecture after the Harvard Mark I computer. Modern von Neumann computers display some traits of the Harvard architecture in their designs, such as in CPU caches.While it is possible to write computer programs as long lists of numbers (machine language) and while this technique was used with many early computers,[35] it is extremely tedious and potentially error-prone to do so in practice, especially for complicated programs. Instead, each basic instruction can be given a short name that is indicative of its function and easy to remember--a mnemonic such as ADD, SUB, MULT or JUMP. These mnemonics are collectively known as a computer's assembly language. Converting programs written in assembly language into something the computer can actually understand (machine language) is usually done by a computer program called an assembler. Machine languages and the assembly languages that represent them (collectively termed low-level programming languages) tend to be unique to a particular type of computer. For instance, an ARM architecture computer (such as may be found in a PDA or a hand-held videogame) cannot understand the machine language of an Intel Pentium or the AMD Athlon 64 computer that might be in a PC.[36]Higher-level languages and program designThough considerably easier than in machine language, writing long programs in assembly language is often difficult and is also error prone. Therefore, most practical programs are written in more abstract high-level programming languages that are able to express the needs of the programmer more conveniently (and thereby help reduce programmer error). High level languages are usually "compiled" into machine language (or sometimes into assembly language and then into machine language) using another computer program called a compiler.[37] High level languages are less related to the workings of the target computer than assembly language, and more related to the language and structure of the problem(s) to be solved by the final program. It is therefore often possible to use different compilers to translate the same high level language program into the machine language of many different types of computer. This is part of the means by which software like video games may be made available for different computer architectures such as personal computers and various video game consoles.The task of developing large software systems presents a significant intellectual challenge. Producing software with an acceptably high reliability within a predictable schedule and budget has historically been difficult; the academic and professional discipline of software engineering concentrates specifically on this challenge.computer salescomputer repair

Plug Computers Computers in the Socket

2011-11-17T09:54:00.000-08:00

Marvell Technology Group Ltd., a company that makes chips for a range of high tech products, communications equipment, cellphones, etc, has planned to launch a new kind of computer. The company has named it “Plug Computers”. Like its name this device would be plugged in to home electrical sockets and would be of socket like size. Yet it will have enough power to manage user's digital media and enable them to view it over the Internet from outside the home.In today's digital world we store each and every information in the digital form as texts, images, videos in digital cameras, cellphones, notebooks. In such a way we are storing our personal information in dispersed style – in the form of files, that make them inefficient as well as risky. Losing a laptop or mobile phone will cost us losing a precious photo or video.Marvell is promoting the "plug computers" as a perfect solution for this. The idea is to have an ultra-small computer plugged into an electrical socket. Despite the small size the plug computer will have enough processing power and network connectivity to manage and serve media stored on an attached thumb-drive or hard drive. You can access the plug computer over your home network, enabling you to get at your files from wherever you needed in your house.However this idea is not new and Apple's Time Capsule works a little like that. It acts like a central repository for data by wirelessly backing up all the connected Macs. HP's MediaSmart Servers are a host of "smart" external hard drives connecting a PC via USB and store your media longterm, and serve it to connected TVs and audio systems without needing the PC's intervention.Marvel is planning to miniaturize all this technology and make it small and convenient. The company is also emphasizing on the green aspects as well by maintaining the eco friendliness of the plan. Plu computers are supposed to draw less than 5W of power that is much less compared to a PC running as a media server.Company is planning to launch it on a small and economic-enough scale. Marvell will be sourcing the chips while partner companies make the software & hardware. The price is interesting targeted at $50 that makes this idea different from other tech solutions.

Certified credential and wide experience confirm that they have necessary skills required for PC troubleshooting problems faced by computer users. If you have experience repairing desktop computers, you may at some point wonder how you will fare with laptop computers. Learning laptop self repair is not for the faint of heart. While laptops and desktops have a lot in common as to how they operate, the architecture behind them both is a different story. The exclusive nature of laptop hardware makes the repair process a challenge.Software related laptop problems are fixed in a similar manner to desktops. Most laptops use the same operating systems you would find on desktops. The main difference with repair lies in how hardware problems are handled. You can say that being proficient in laptop self repair depends on your ability to handle laptop hardware problems.Like the desktop, the laptop has a motherboard as the central component. The size is smaller to what you would find in desktops and varies from laptop to laptop since there is no real standard. A lot of the components are directly integrated onto the motherboard and unlike desktops, customization is limited. It is also not practical to build a laptop from scratch using compatible parts like you would with a desktop.Getting a laptop open, usually takes significantly longer than opening a desktop case. The laptop shell contains several little screws (usually at the bottom) for you to remove. There may be certain parts on the inside of the laptop you can gain access to very quickly. These may not require removing lots of screws. Examples include, the battery, memory module or hard drive, but it depends on how the manufacturer factors in accessibility during the design process.Memory modules, hard drives and batteries are the easiest parts to replace in a laptop due to design standards that many manufacturers follow. If you encounter a serious problem, that requires replacement of these parts, you just need a new part that is compatible with the housing of the old part. For example, replacing a faulty SO-DIMM DDR2 memory component with a newer one. Checking the manufacturer's website or laptop manual for compatibility info will help as well.Getting to most of the other components require going very deep into the laptop, disassembling piece by piece. Depending on the part you are trying to locate, you will usually encounter other parts and screws of varying sizes in the way. These obstacles are way more intrusive compared to what you get in a desktop. Like desktops, you need to take precautions to hazards like electrostatic discharge.Laptops are more expensive to repair than desktops in most cases. One of the most expensive parts to replace is the laptop LCD screen if it is badly damaged. Any replacement screen must match the specifications of the damaged one. Finding the right screen can be a challenge.These are just some of the challenges you will have to face, if you are going to specialize in laptop self repair. If you are making money repairing desktops and don't know how to repair laptops, you are leaving money on the table. Having the knowledge and skill to repair laptops can easily boost your income.

Saving For Children's Education

2011-05-07T19:59:00.000-07:00

One of the most common financial goals that couples have is to save money for their children's education, whether that be at a private school or a tertiary institution. Saving for this purpose is no different than saving for any other goal in life, yet there is a common misperception that funds need to be set aside separately or even in the child's name for this purpose. That can lead to a lower rate of investment return in some cases.

If you are going to save for your children's education, then you're probably looking at saving tens of thousands of dollars and it will take a number of years to get to that target.

That means starting when the child is young - in fact, probably at the preschool age. Anybody with preschoolers most probably has a mortgage. With mortgage interest rates being so high, the best place to put your money is into your mortgage to keep the interest payments down. If, for example, you are paying say 7.0% interest on your mortgage you would need to earn at least 7.0% after tax on an investment to make it worthwhile investing and not paying your mortgage. So pay off your debt as fast as you can, and then remortgage later if your still really want to help your kids. If you have grandchildren that you wish to provide for, the situation may be a little different. You probably won't have a mortgage and you may wish to make funds available that are clearly earmarked for your grandchildren and clearly specified to be used only for education costs. A good way of achieving these objectives is to set up an education trust. This can be done through a solicitor or trustee company. There will be a fee involved to establish and maintain the trust, but there will be safeguards in place to ensure that the funds are used for the purpose you intend. An education trust can be particularly useful in certain situations, for example, where there is a relationship breakdown between parents and a parent or grandparent wishes to make funds available without the risk of the money being used for a different purpose. An education trust can also be used where funds might be at risk of a possible future claim by business creditors.

Students with disabilities are not students who are incapable of learning but instead are students who may need material presented to them using alternative methods. Methods that incorporate art can be very successful for these children.

Many students with disabilities are separated from regular students for either part of all of the school day. These students spend a great deal of time focusing on remedial skills and learning new skills to help them catch up with the rest of the class. For students with learning disabilities the knowledge that they are not able to function at the same level as other students can be very discouraging. Introducing these students to art classes can offer them the opportunity to do something creative where success is not measured by the same standards as in regular academics. The feeling of succeeding at something can provide these students with self-worth and confidence that can carry over into other areas of study. Allowing children to be involved with art related activities also encourages creativity, problem solving skills, motor skills and other skills that are useful in all areas of academics like math, science and language.

Art lessons can be combined with traditional lessons and used as a teaching tool for these students. Children that have difficulty with verbal expression will often have more success by expressing themselves through art. Practicing expression through art may translate to better overall communication skills. Teaching math and science lessons that are hands on art based lessons also tend to hold a student's interest more than traditional lecture lessons. Sometimes just holding a student's attention is half the battle especially for students with attention deficit disorder. Activities that encourage drawing and painting can help students learn about shapes, contrast and spatial relationships. Teachers can implement lessons that use these art activities to teach basic math skills like geometry and various other math techniques. Another interesting way to teach history involves having students create plays that focus on historical events. This method can help students internalize the material as oppose to just memorizing facts from a textbook.

How to Ensure A Good Education for Your Deaf Child

2011-05-07T19:56:00.000-07:00

Having a child with disabilities isn't easy. If you're the parent of a deaf child, then you know this as well as anyone. Whether it's a physical, mental, emotional or psychological disability, the fact is that the world isn't really built for people who are different, so chances are you've already ruled out the notion of keeping your child in the public school system and you're looking at deaf school options or possibly home schooling.

Home Schooling for Deaf Children

There are a lot of arguments for and against home schooling for deaf children. The fact is that your child may well wind up learning more through staying home and being taught by people he or she loves and trusts than by going to a special school to learn. The downside is that this can have an adverse effect on a child's developing social skills. By simply staying home, within their comfort zone, they may not learn how to deal with others until their early adulthood.

On the other hand, you may well be able to find a home schooling community for hearing impaired children, but i you don't live in a big city, this may be much easier said than done.

Deaf School Options

At a school for the hearing impaired, children may have some difficulty adjusting, at first, to being surrounded by new people. However, over time, the benefits do seem to outweigh this. A child who goes to a school for the deaf will, first and foremost, realize that perhaps they're not so different after all. By being surrounded by those who understand hearing impairment and those who suffer from hearing impairment themselves, a deaf child may feel much more comfortable and be much more willing to simply learn and stay focused in a more comfortable environment than that which public schooling provides.

Another benefit is that you're likely to meet other parents of deaf children through the school, other parents who know how difficult it can be and who understand that behind the disability is a unique individual. At a school for the deaf, and within the surrounding community, your child isn't a "deaf kid", but a person who may be exceptionally intelligent or creative, who may be athletic or have a great sense of humor. In being around other deaf people and those who see your child as a person, not as a disability, your child may really bloom as an individual and learn to take pride in who he or she is.

Importance of Holistic Education for Children

2011-05-07T19:54:00.000-07:00

No one can really argue with the fact that formal education is one of the most essential factors of human lives, which is essential for fostering human values and dream careers. At the same time, it does have its limitations, and that could hamper the development of growing children.

Most of the systems in the schools are designed in a manner which is fundamentally aimed at transforming the children into citizens, who would naturally flow with the wave of professional responsibilities. This could forestall the talents and passions in children from being identified or pursued.

The wholeness of children development in the schools goes unexplored, primarily due to the increasing numbers of students in the classroom, and also due to the overwhelming syllabus that has to be completed within that given academic timeframes. The situation minimizes the possibilities of finding multiple intelligences in children.

Besides their normal syllabus, it is also very essential for the children to learn more about themselves, and about how to build relationships in their lives.

Both attitude and aptitude in children has to go hand in hand, in order to contribute towards their success as they go on to become great personalities. Additionally, they will also need to develop a lot of resiliency and will power to face difficult situations in their lives.

Apart from talents and education, the children might require extra attention on their emotional developments as well. This will also help them in developing proactive social behaviors.

The world has changed a great deal with the advancements in technology, and the children these days are blessed with access to a lot of information when compared to the past. The media is able to reach the children directly now more than ever before.

This could also create a lot of confusions in the little minds, as information overload can also be too overwhelming for the children. The parents cannot overlook the fact that the exposure to abundant media and information could also cause negative influences on their little ones.

The institution of formal education in schools is very important, but holistic education of children will help them to cope up better with their lives. There are just too many things to consider for proper upbringing of children, in order to help them pursue their individual passions. They will need a lot of guidance in helping them identify their strengths and weaknesses.

Music Education For Children

2011-05-07T19:52:00.000-07:00

Studies have shown that music and music training provide a wealth of educational benefits to children. Early exposure to music has been proven to help develop areas of the brain responsible for language and reasoning skills. Music education also increases the spatial and temporal reasoning necessary for advanced mathematics. Children who study music typically score better on standardized testing as well.

Music education not only provides children with a terrific healthy outlet for self-expression, it enhances creativity and boosts self-esteem. There are a number of ways for parents to help their child receive quality education in music, starting as young as birth. The most important thing is to expose your child to a variety of music, including several different genres, not just classical or kid's music.

Sing songs to your infant each day. Fun, repetitive songs with movements or motions are best and as your child gets older, you can encourage her to join in. By the toddler years, your little one can dance along with music. Continue to sing simple silly songs with your toddler and dance together to a variety of songs, both upbeat and slow. Toys, like the Baby Einstein Learning Sounds Piano, will allow your toddler to create her own beats and songs.

Preschool age children can begin to differentiate between tones and pitches. Play games to pick which note is higher and which is lower. Introduce your preschooler to the specific sounds made by various instruments as well. Continue to listen to many different types of music with your preschooler and discuss how various pieces make you and our child feel.

Make musical instruments with your preschooler and play them together. Shakers are easy to make out of ordinary household items. Attach two paper plates together with a hole puncher and yarn or cover the ends of a toilet paper tube with construction paper and fill either with dry beans or rice. A coffee can and lid can be used as a drum. Have fun and use your imagination to create your own family band.

You may want to start formal music education with music lessons at this age. Discuss how various instruments are played and allow your child to choose the one he would like to learn. Visit a symphony or orchestra performance to investigate the various instruments. Piano lessons are typically best for this age because your child will learn to read and play music without having to remember difficult fingering techniques.

Benefits of Music Education For Children

2011-05-07T19:50:00.000-07:00

Do you ever wonder what advantages are achieved through learning music? Read on to discover the many benefits of music education.

Self-Esteem

Learning music is hard work, but also very rewarding, which can lead to a genuine increase in self-esteem. This can happen when a student masters the many steps along the way to becoming proficient, as well as when they have a successful recital or concert.

Increased Memory

One of the many benefits of music education is that it is a great workout for increasing memory as the student learns to recognize the different notes.

Self Expression

Music can be a creative outlet for self expression. This may take the form of learning music that mimics experienced emotions. Or it may be expressed in creating music and lyrics, which can then be presented to family and friends.

Bringing People Together

Music can be a great catalyst for uniting people in a common experience, where friends can be made, and a sense of belonging can be available.

Increased Academic Performance

When talking about the benefits of music education it is often well believed that learning music can boost academic achievement. Although the exact mechanics of this is often not understood, the belief is that learning music stimulates parts of the brain that then have a carry-over impact on all academic areas. It also provides structure and focus which may benefit other areas of learning.

Teamwork

Learning to work well with others is one of those things that when present is often overlooked, but when absent is often painfully obvious. Performing music requires the skills associated with teamwork that are valuable throughout life. In order to play an instrument successfully students need to be tuned in to what those around them are doing so that the various instruments form a cohesive unit.

Structure, Organization, and Discipline

When talking about the benefits of music education it is important to acknowledge the value that can be found in the structure, organization, and discipline that it offers. Structure and organization are important skills to be learned. They can carry a child forward in many areas of life, not just music education. When talking about discipline here we are discussing the discipline it takes for the child to set aside time each week to practice. Learning to discipline themselves can eliminate procrastination, and like structure and organization, can be valuable in all areas of life.

Computer Education For Kids

2011-05-07T19:49:00.000-07:00

Computers have become a common and needed part of life in today's society, making computer education imperative for children. Young children will typically begin to show an interest in the home PC by their toddler years. While it is may be a good idea to begin introducing your toddler to the computer in very short sessions, most children can began to learn and understand a computer's functionality by preschool age.

Preschool age children can learn to turn the computer on by themselves and will quickly learn to operate the mouse. Simple games that teach and reinforce basic school readiness skills are great for this age. Computer education for preschool age children should be limited to short sessions of about 30 minutes a few times a week.

Many childcare facilities offer computer time as part of their weekly curriculum for preschoolers. Structured games and activities give young children an opportunity to explore the way a computer works. Games that require dragging objects across the screen are excellent for building mouse skills in beginner users. Chose age-appropriate software and websites that involve alphabet and color recognition, shapes, counting, or short stories that are read aloud. Activities that feature music are also enjoyable for a preschooler's computer time.

Kindergartners are normally still exploring the basics of computer use and will probably do best with activities that reinforce simple skills. As children become more comfortable with the computer, more complex games and activities can be introduced. Computer education for kindergartners typically consists of short sessions of no more than an hour, playing games that correlate with their classroom learning material.

By first grade, children have usually gained a good understanding of how to use a mouse and they are learning to use keyboard letters to type. Games like Typing Instructor for Kids can help young children become fast and efficient computer users. Early elementary age children are ready to move beyond simple reinforcement and skill drill activities to the many different functions of a computer.

First through third graders should use the computer as a supplement for their classroom work. A student studying about stars and planets can use the internet to search for pictures and information about constellations. An assignment about Africa can include a search for videos of African animals. Allow your child to work on his own, but stay close by to prevent access to inappropriate content and to answer any questions.

Software programs that allow children to create, like an art or publishing suite designed specifically for kids, can boost creativity along with providing exposure to technology. Grade level skills can also be practiced and enhanced with math, reading, and spelling computer games. There are a number of kid-friendly websites that provide search engines, games, and interaction opportunities.

Career Education For Kids

2011-05-07T19:48:00.000-07:00

Career education for children at an early age can prove to very beneficial. Kids can obtain career education through vocational schools or programs, or through home schooling. A number of career education institutes operate online as well.

In cases of home schooling, parents have total control over the needs of their children and have the flexibility to teach them ethical values. For subjects that parents feel uncomfortable teaching, they can hire a tutor, or the child can go to a vocational school for this purpose. Parents can also send their kids to vocational schools for professional guidance.

Career education institutes follow a specialized curriculum prepared well in advance and modified depending upon a child's specific needs and talents. They also have field trips that combine practical and acquired knowledge for a creative learning experience. The curriculum of career education for kids can incorporate topics such as religious and moral beliefs along with educational knowledge. The main reason for career education for kids is that they can reach their full potential in an environment that is exciting and creative. They can start enhancing their knowledge and skill in fields that they are interested in at an early age. In many cases, parents and teachers work with students one-on-one to bring out individual talents and develop teaching methods that work for each child.

Parents can search the Internet for lesson plans, vocational schools and other topics of interest. Career education includes skills, processes, techniques, tools, and raw materials needed for guiding young children. The goal of career education is to empower students to participate effectively globally, and become world-class workers and citizens.

Financial Education For Children's Success - 8 Unique Ways to Introduce Children to Entrepreneurship

2011-05-07T19:47:00.000-07:00

Does talking to children about entrepreneurship at an early age make sense? Our school system is set up to lead our children into the workplace as employees, not employers. Now don't get me wrong, we as a society definitely need employees: police officers, firefighters, doctors, nurses, etc., but why not shine some light on entrepreneurship too?

Incorporating the principles and philosophies of success with emphasis on teamwork, community involvement, and entrepreneurship go well with all types of learners of varying ages. Children deserve the opportunity to at least hear about what entrepreneurship is, why they may want to be entrepreneurial, when they could do this and, of course, how to be an entrepreneur. We find that children are very responsive when talking about making money on their own. As early as six years of age, children are starting to realize the importance behind making your own money vs. working for someone else. Unfortunately, not enough children in the world are being introduced to this kind of lifestyle. So below you will find some great tips, in no particular order, to help introduce your child to entrepreneurship.

1. Story Time

A great way to get your child started is by sharing with them inspiring stories of kids today, who are already entrepreneurs. The internet is a great resource, making available great stories about kid entrepreneurs from around the world, what they are doing right now and how they are doing it. When sharing inspiring kid entrepreneur stories ask your children questions like: How did they do that? Why did they do it? Do you think you can do something like that? What makes you feel that way? If you get an answer like "I cant do that," then just follow up with "Well, if you could do that, how would you do it?" This usually gets an answer. Oh, and don't forget to show your kids pictures, watch video's or check out news clips of kid entrepreneur's. Its also quite effective when kids hear the stories right from another kids mouth.

2. Field Trip Fun

Contact local businesses, churches or news agencies to see if you could arrange for your kids to visit with them and get a behind the scenes look at how the particular business operates. Approach businesses that hold a high interest level for your kids. Let the places know that your interested in a behind the scenes look at their business operations for your children and their friends who are learning about entrepreneurship. I highly recommend that you bring your children's friends too, so you all can enjoy the experience together and so that your child has like minded individuals to discuss their findings with.

3. Raising Some Bucks

Have a fundraiser for a cause that is very important to your child or have them pick products they think they can sell either in the neighborhood or to local businesses. Let your kids bring in some of their friends that want to be a part of the action. Have them brainstorm ideas and narrow the list down to a few that they all agree on. Assist them in organizing the timing and the locations they conduct these "business meetings."

4. Make Planning Fun

Start planning with your kids. For the younger kids create a plan book from scratch, even some of the older kids can get into this too. Design it however they want. They can add stickers or make fancy title pages within their planner. The point here is for them to personalize it as much as they like. You can even pick up an inexpensive planner for their use. Talk to them about the importance of using the planner daily, and getting into the habit of planning for each day the night before. Explain to them how this will start to free up more time for them to do the things they want to be doing, instead of just doing the things they have to be doing as they become more focused. In addition to a planner/goal book, have children create a journal as well, writing down brief entries into a personal journal on a daily basis of things that interest or perplex them is a great way to get them started with being responsible, planning for their future, and allowing them time for natural, real world problem solving!

Too much hysteria over cyber-attacks —US experts

2011-02-16T21:45:00.000-08:00

SAN FRANCISCO - Overblown talk of full-on cyber war between nations fueled by recent attacks like the computer worm Stuxnet could hamper Internet security efforts, officials and experts warned Tuesday.

Serious attention should be paid to threats of cyber-attacks from hackers, spies and terrorist groups but not to the extent of mass hysteria, speakers at the premier RSA computer security conference in San Francisco said.

"Cyber war is a terrible metaphor," said White House cyber security czar Howard Schmidt. "Don't make it something it's not."

Core2Duo vs Dual Core

2009-05-13T00:42:00.000-07:00

Dual core is a generic term representing 2 cores on a single die. Likewise, quad core represents 4 cores on a single die.

This is different from Core Duo and Core 2 Duo. These are micro-architectures for how the CPU operates. Core was Intel's first dual core architecture, and Core 2 is the "sequel" to Core.

So you see, a CPU can be a Core Duo with 2 cores, or it can be a Core 2 Duo with 2 cores. They are both dual core -- the difference is the micro-architecture.

Simply put, Core 2 is a faster, more powerful micro-architecture.
