What is computer Processor/CPU? How it works?

The complex procedure that transfer raw data into useful information is called processing. To perform this transformation, the computer uses two components the processor and memory. 

A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The processor is like the brain of the computer, the part that organizes and carries out instruction that come from either the user or the software. 

In a personal computer, the processor consists of one or more microprocessor, which are silver of silicon or other material etched with many tiny electronic circuits. A microprocessor is plugged into circuit board (a rigid rectangular card containing the circuitry that connects the processor to other hardware.

The circuit board to which the microprocessor is connected is called the motherboard. In some powerful computers, the processors consist of many chips and the circuit boards on which they are mounted. The term center processing unit (CPU) refers to a computer’s processing hardware, whether it consists of single chip or several circuit boards. This circuital part of the computer occupies amazingly small space in the computer.
