Computers help children to be in control of their experience, to set their own pace, and to select the level of challenge with which they feel comfortable. Computers help children to use all of their senses to extract information. Computers fascinate kids and can draw their full attention, which often results in a deeper focus and concentration. Computers enable children to learn through creating, just as they gain hands-on knowledge and understanding when they build forts, make up stories, and paint, increase their skills. Good educational software enables children to develop and practice a broad range skill. It can help them learn, for example, about letters, numbers, shapes, colours, and rhythm. Good software can also help children develop their understanding of cause and effect, higher order problem solving, procedural thinking, and creative expression.

Disadvantages
The teenagers of today's society have changed dramatically due to the Computer. Nowadays, the majority of teenagers have a PC and it has played a key role in their lives. Teenagers need to be equipped with knowledge of computer technology, as most things in life require the use of computers. One disadvantage of owning a computer is the information that students can access from the Internet. The Internet has also made the youth of today quite lazy, especially in terms of their education. If a student needs to research information for school, they merely access a relevant site and download the information, rarely paying attention to what is written. Purchasing the network cabling and file servers can be expensive. If the file server breaks down the files on the file server become inaccessible. Viruses can spread to other computers throughout a computer network. There is a danger of hacking, particularly with wide area networks.
Computers are very engaging on children as well as adults. Kids with access to software that is not age appropriate may be exposed to such negative influences as violence, strong language, and over-stimulation from fast-action graphics.
