What is a microprocessor?

The word micro stands for small and a processor is a device which has computing i.e. data processing capability.

That is a processor on a single microchip.

Microprocessor uses small number-holding areas called registers to perform arithmetic and logic operations.


When a whole processor(CPU) is integrated on single small chip or few chips, then it increases efficiency and reduce the cost of processing power.
