Computer has come to pervade all as- pects of human life in entirety You just name a field, and there can be found suitable computer applications for it.

In its initial stages it was a mechanism for speedy calculation of data.

Computer began to acquire its present look during the Second World War when minute calculations were re quired to locate the enemy precisely and fire upon it. The former act could be performed with the help of a radar while the latter task was sought to be achieved with the help of a computer.

A computer is a great asset to man due to its various features. It performs all the tasks entrusted to it at a rapid speed saving on manual labour, More over, its storage capacity is great while maintaining accuracy and reliability.

Computer has passed through four gen erations of development. Scientists are making efforts to invent the fifth gen eration computer. It is visualised that it would be a machine that would think and act just like man. So far, it can work according to the programme fed in it. But the fifth generation computer is expected to take independent deci sions because of the artificial intelli gence being developed for it.
A question is often asked Which is greater : man or computer? Let us not get trapped in this argument, be cause despite all the uses of computer, it would remain a machine which has been invented to help man in discharg ing his wide varietyof functions. It can never replace man as it cannot think and feel.
It has no place for sentiments It can rely only on memory which is subservient to programmes which man makes. On the other hand, man is the creature that God Himself created so that life could go onIt is a sad fact that man has come to depend on computer to the extent that he himself now resembles a machine
