What is a Computer?





The term computer is derived from verb compute, which meaning is to calculate, but the computer is used in very vast sense. It is not only computing device but it is able to process all type of data logically, mathematically, sophistically, effectively and efficiently.

It is an electronic device used to manipulate data into information with very high speed.

The definition of Computer is given in Oxford Dictionary as “An automatic electronic apparatus for making calculations or controlling operations that are expressible in numerical or logical terms.”

Computer as a System: The system is an enclosed structure to take several inputs for processing and returns single output. Computer is a system. There are only two types of systems:

(a) Natural system, and

(b) Fabricated or artificial system.

The systems available in nature are termed as natural system. The solar system, the river system, Digestive system, Nervous system, Glandular system etc is examples of natural system.

The artificial systems are man-made systems. The schools, college, University, Business organization, Management Information System, Computer, and Networking etc are fabricated systems or artificial system.

The computer system has three major departments- input unit, Output Unit and CPU. These all departments are busy to manipulate data into information. Input Unit takes data and give to CPU, CPU processes it and Output unit demonstrates result.
