What is Microprocessor?.

Microprocessor :The Microprocessor is a chip that accepts Data and instruction, processes it and gives to output. It control the computer system. it is brain of computer. it control all process of computer system.
The microprocessor may also have a cache memory to store information; it can access information faster from the cache than from the RAM.
