CPU (Introduction)

CENTRAL PROCESSING UNIT

CPU (Central Processing Unit) or processor is an important part of every computer system because of its work like a brain for every computer system.


CPU COMPONENTS
CPU components can be classified in the following three categories. 

1. ALU (Arithmetic Logical Unit)
This component is responsible to perform all types mathematical operations (+, -, *, /) and logical operations (<, <=, >, >=, ==, <>)

MATHEMATICAL OPERATORS

OPERATOR	MEANING
+	Addition
-	Subtraction
*	Multiplication
/	Division

LOGICAL OPERATORS

OPERATOR	MEANING
<	Less than
<=	Less than or  Equal to
>	Greater than
>=	Greater than or Equal to
<>	Not equal

2. CU (Control Unit)
This component work like a computer's nervous system and responsible to control all types of internal activities and processing.

3. MU (Memory unit)
The 'memory unit' responsible to provide memory space to store temporary data, intermediate result and CPU data during any processing.
