What is A Computer?
The word “computer” comes from the word “compute” which means to calculate. So a computer is normally considered to be a calculating device that can perform arithmetic operations at enormous speed.

The electronic computer is the most versatile and efficient machine for processing data.

Generally, the word COMPUTER means Commonly Operated Machine Particularly Used for Training Education and Research.

More accurately, a computer may be defined as a device that operates upon information or data. Data can be anything like bio-data of various applicants when the computer is used for recruiting personnel, or the marks obtained by various students in various subjects when the computer is used to prepare results, or the details.

Thus, data comes in various shapes and size depending upon the type of computer application. A computer can store process and retrieve data as and when desires. The fact that computers process data is so fundamental that many people have started calling it a data processor.

A computer is an electronic device made up of electronic circuits and wires etc. In modern age, computer (which is nothing but just an electronic device) is the most advance tool for solving the wide range of practical problems.

More precisely computer is an electronic device which works under the instructions of stored programs, automatically accepting the supplied data to analyze and process the data to produce the information called the result or output of that processing.

It manipulates the number of symbols, which it accepts as input, process this input are reproduces this is as output in a formatted manner. The word computer has been derived form the word compute.

When computers were developed, it was thought that they would be fast calculating machines. But today most of the work done is of non-numerical in nature like processing the records of students or employees of details of passengers for reservation.
