Basic Working Principle of a Computer

A computer is an electronic machine that converts data into meaningful information by performing various actions on the data. A computer accepts the raw data from the user through input devices such as mouse keyboard etc processes them according to the given set of instructions, display the result as a human understandable form through an output device such as to monitor and printer, which called information and stores them for future references. Such operation performed by a computer is called the Information Processing Cycle or the basic working principle of the computer. The working principle of computer defined as below.

“The basic working principle of a computer is a set of steps the computers follow to receive data, processes the data according to instructions, display the result to the user and stores the result.

The basic working principle of a computer has four steps. They are as follows.  

Input: This is the first step of the basic working principle of a computer. During this step, the computer takes data from the user through input devices such as a keyboard, mouse, joystick, scanner, camera, microphone, etc. and provides to the computer for processing. 

Processing: This is the second step of the basic working principle of a computer. During this step, the computer’s processing device CPU processes the input data according to the given set of instructions.

Output: This is the third step of the basic working principle of a computer. During this step, the computer displays the result of processing. After processing input data, the computer gives meaningful information called result or output. The monitor, printer, plotter, speaker, etc. are the common output devices of the computer.

Storage: This is the fourth step of the basic principle of a computer. In this step, the computer permanently stores the processed result or output on the storage devices like Hard disk, Pen drive, CD/DVD etc.
