A computer can be defined as a machine which stores information, data etc., on magnetic tapes, analyses and retrieves the same instantly when required. Thus, it has helped us in overcoming many difficult problems of multiple calculations, data processing, recordkeeping, scientific analyzing etc. As far as storage of information and calculation of data are concerned it has surpassed common human mind. The speed, accuracy, reliability and capacity of a modern computer are really astounding. In short, a computer is a fantastic machine.

Sometimes fears are expressed that computers may surpass and overtake human mind. But in all probability these fears are baseless. Computers can never supersede the human brain. After all computers are only machines, and brainchild of man. In spite of all advancements and developments in computer-science and technology, computer would remain a machine. It may defeat a grandmaster in a game of chess, compose music, draw and paint, write poetry or a novel, and yet it can never match a human brain. Super computers can never be so super as to supersede human brain. There are extraordinary brains like Sakunthalai Devil, before whom a computer seems a pigmy in very complicated calculations and data processing. Computers cannot compete with man, for they lack human intelligence, feelings, creativity, originality, imagination, consciousness etc. Computers are wonderful; they have made paperless office work and trading possible. Besides there are many other achievements to their credit, yet no machine however subtle, super or sophisticated, can match, /let alone superseding, human mind. Computers always depend on human efforts and consciousness for their operations and working.
A computer works fantastically; its operations are subtle, complex and wonderful. It has seen phenomenal progress and up gradation in the recent years. The coming computers would be for faster, complicated, reliable, powerful, small, handy and light. Each successive generation of computers has proved it. Now note-book pocket computers are a very common thing. Gradually the personal of computer would become a consumer appliance. It will be a matter of course. Computer will further revolutionize our life and working. We can very well look forward to more fantastic breed of computers.
