‘a microprocessor functions as the central processing unit of a microcomputer’; ‘a disk drive contains a microprocessor to handle the internal functions of the drive’;


A small computer based on a microprocessor; in practise, at any given time in the technology of computer development, a microcomputer will be one that is less powerful than a minicomputer.


A microprocessor is a computer processor wherein the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer’s central processing unit.
