Microprocessors

A Microprocessor is an important part of a computer architecture without which you will not be able to perform anything on your computer. It is a programmable device that takes in input performs some arithmetic and logical operations over it and produces the desired output. In simple words, a Microprocessor is digital device on a chip that can fetch instructions from memory, decode and execute them, and give results. 

 

types of microprocessors-

Here are the five main types of microprocessors:
