A mere pressing of a button can off-load your heavy mail let you know all statistics on various subjects, place before you and control your other machines. Programmed computers are being used in controlling and monitoring the movement of traffic, reservation of seats in airways and railways, in educational institutions, in defense establishments, in ships and planes all over the world.
In India, computerization of important sectors like defense, energy, steel, mining, cement, railways, airlines, communication and education has already taken up. There is need for adequate trained manpower without which computers cannot be effectively utilized.
Although the use of computers has phenomenally grown, it has some fundamental limitations. The computer cannot exercise judgement or commonsense. It has to be meticulously instructed in the programme and it acts as it is instructed. It is also alleged that the privacy of people is being threatened as every detail regarding a person’s whole life can be squeezed into a few centimeters of computer tape. Also the use of computers is adding to unemployment all over the country as a single computer can do the work of hundreds of manual workers.

The computers have so revolutionised the day-to –day life of human beings that it has encompassed its every activity. The explosion of Information Technology, the Website and the windows have thrown all the knowledge of the world at man’s feet.
