CENTRAL PROCESSING UNIT [CPU]

The Central Processing Unit [CPU] is the brain of any computer system. In a computer system all major calculations and comparisons are made inside the CPU. The CPU is also responsible for activating and  controlling the operations of other units of a computer system. The control unit and the arithmetic logic unit of a computer system are jointly known as the Central Processing Unit. While the control unit takes care of the flow of data from input unit to storage unit and the flow
of final results to the output unit, the arithmetic logic unit is the place where the actual execution of instructions taking place during the processing operation.

The Central processing Unit consists of the following main components:
Switched Mode Power Supply [SMPS] - for converting the current voltage, Mother Board [ROM]. Arithmetic Logic Unit [ALU], Control Unit[Ram],Hard Disk – Storage unit, Floppy Disk – storage Unit, CD ROM – Storage Unit
