An electronic circuitry in the computer that carries
instructions of program by preforming basic arithmetic
, logic, input output (I/O) operations.
This is also called “Brain Of Computer”.

4. Control Unit: (CU)
 It Behave like a traffic signal directing the flow of data
through the CPU.

5. Arithmetic Logic Unit: (ALU)
Computer do two types of operations;
(i)Arithmetic Operations (ii)Logical Operations
Arithmetic Operations include Addition , Subtractions , Multiplication And

Arithmetic Operations include Addition , Subtractions , Multiplication And
Division.
Logical Operations include Comparisons , such as determining whether one
number is equal to , greater than , or less than another number.

6. Memory:
 The CPU contains the basic instructions needed to operate
computer , but it cann’t store entire programs or set of data
permanently.
 CPU needs millions or trillions of bytes of space where it can

 CPU needs millions or trillions of bytes of space where it can
read or write programs and data while they are being used .
This area is called “Memory”.
 It consists of chips either on the motherboard or on the small
circuit board attached to motherboard.

7. Types Of Memory:
There are two main types of memory;
(1)Volatile Memory (2)Non Volatile Memory
Volatile Memory:

Volatile Memory:
“RAM” is also called volatile memory.RAM is the abbreviation of “Random
Access Memory”.Volatile Memory requires power to store data.
Physically it Consists of chips on a small circuit board.
It hold programs and data while they are in use.
