A computer is an electronic machine that operates under the control of the set of instructions (programs) stored in its own memory characterized with an ability to accept, process and store data that can then be retrieved easily for a variety number of uses.

Unorganized or unprocessed symbols, figures and facts are typically known as Data, while the processed, valuable, meaningful and useful ones are known as Information.

The computer works in interaction with computer hardware and software. This technology has become an important and major part in our daily lives. You can’t pass a day without using anything made available by using the computer system.

When you are watching movies, listening to radio, surfing or browsing the Internet or the World Wide Web (www) making a Telephone Call, sending E-mail messages or playing games, you are really using the computer technology.

The computer can also help you do mathematical calculations and almost all the results are actually correct more than a human being can do it manually.
