The Central Processing Unit (CPU)

The Central Processing Unit:-

The Central Processing Unit or CPU is also called the Brain of a Computer. It is a very complex integrated Circuit. It is build up of millions of tiny components integrated together. It is mainly divided into 2 units.
Arithmetic and Logic Unit (ALU)

Control Unit (CU)

Arithmetic and Logic Unit (ALU):-
The arithmetic and logic unit is the place where main processing is done. It performs Arithmetic Calculation (addition, subtraction, multiplication and division), while Logic unit performs Logical computations (compare objects and numbers with logical statements. Hence ALU manipulates the data.

Control Unit (CU):-

Control Unit maintains, orders and Controls the processing activity in the CPU. It directs the sequence of Operations.
