Science has discovered many wonders and computer ins one of them. It is an ultra modern electronic device for storing and analyzing information fed into it. It has no capacity to do anything by itself. It works on the basis of commands given by the operator. 

Computer was not invented over night. First of all pascal invented the theory of Digital Calculating system in 1642. Though his attempts were not crowned with success, he initiated the research which paved the way to the invention of computer. Finally Mr. Haward Akin, an American scientist invented such a machine in 1937 that could do difficult sums. So the credit for the invention of modern computer goes Haward Akin. After seven years electric computer was used in Harvard university in 1944. After that many other computers have been invented such as Ed Sac in 1945 and ENTRANCE in 11946 etc.

A computer consists of five major components. They are the input unit, the, the output unit, the memory unit, the control unit and arithmetic unit.

A computer performs three functions: 1. It receives data, 2. It processes data by various computations, 3. It emits data. 

Every computer has a machine language of its own and accordingly  a computer functions. Machine language is not fixed. It varies from machine to machine. Programmers written in machine language are machine dependent and they are only good for for that are only good for that particular machine. 

Of late computer has been introduced gas been introduced in china. Many government and non-government offices,educational institution are using  computer.

Computer is of great use to us . We can not go a single moment without computers. It is part and parcel in our daily life.
