What is Computer? 

What is Computer: A computer is a man made electronic machine which stores, reads and processes data to produce meaningful information as output. It works very fast and does not many mistakes but its capacity is limited. It is made of English word ‘to compute’. It operates under the control of a set of instructions that is stored in its memory unit. A computer accepts data from an input device and processes it into useful information which it displays on its output device.

Actually, a computer is a collection of hardware and software components that helps us to accomplish many different tasks. Hardware consists of the computer itself and includes a CPU, a monitor, a keyboard, a mouse and any equipment connected to it. Software is the set of instructions that the computer follows in performing a task.
