A computer is an electronic device that manipulates information or data. It has the ability to store, retrieve, and process data.
A computer is a device that comprises both hardware and software. The functions of hardware and software combine together to make the computer functional.
Computer hardware
A hardware device helps to enter input information. The software processes the input data and gives the output to the monitor (hardware device). Thus, a computer is like a human body, where the human body is the hardware, and the soul is the software.
