What is Microprocessor?

Intel Microprocessor

Microprocessor [Intel 80286]

A single chip processor is called microprocessor. It is a semiconductor device consisting of electronic logic circuits manufactured by techniques such as large scale integration (LSI) or very large scale integration. The microprocessor is capable of performing computing functions and making decisions to change the sequence of program execution. A computer built with a microprocessor is called micro computer.

Examples

Intel 8086, Intel 80286, Pentium II

A microprocessor in which most instructions operate on n-bit data and its registers are of n-bit size is said to be a n-bit microprocessor.
