A computer is an electronic device that accepts data or information and manipulates it for some results based on a program or sequence of instructions on how the data is to be processed. Computers have the capability to store data and information. A program may be rigid and built into the computer or different programs may be provided to the computer. Today’s computers can handle both kinds of programs.
It enables us to enter into it numbers, characters, and electronic signals. This is called ‘input’. It is capable of manipulating input in a variety of way. Its processor is versatile. It produces a result called ‘output’ which term ‘information’. The computer can store the input or output for used to examine and use some in the future.
Scientists and researcher use computer to develop theories, to collect and test data to simulate test environment and to exchange information all over the world with their colleagues. Engineers and architect use to computer to design a product. It can be far more productive with a computer than with a pencil and paper. Doctors and medical person use computer from diagnosing illness to monitoring patients during surgery and controlling permanent prostheses. Banking system also use computer to fast and effective service. ATM facility is provided. Money transfer and receiving is also effective.
Although it has many advantages but it has also some disadvantages which sometimes create problem to us. By the effect of virus many functions of the computer can be collapsed and the computer can be hanging. It also create user about the physical illness.
