What is Computer?

1.                A computer is an electronic device for performing logical and mathematical operations based on its programs. In other way, a computer is an electronic device that can accept data and instructions, process them or store them for later retrieval, and sometimes generate output based on the processing. The term includes not only the obvious electronic devices that have a screen, keyboard, printer, and so on, but also computers that are embedded into devices like those at supermarket checkout counters or in a simple calculator.

2.         The computer basically works as per the above system where the raw information is given as input through the input devices. That information is processed based on the logical and mathematical instructions feed previously inside the central processing unit of the computer. While the processing is going on, the main processing unit preserves the information as well as the necessary logics and formulas inside its permanent and temporary storage devices. After the processing is done the processed data are displayed or shown by the means of output devices.
