"Central Processing Unit (CPU)"
Processing Device means calculation comparisons and
decisions. The processing device is Central Processing Unit CPU); also called
Microprocessor is a small chip in Computer which receive Input and provide
Output. It is composed of silicon and contains millions of transistor for e.g
Pentium, Dual Core, Core 2 Duo, Core i3, i5, i7 etc. It consist ALU, CU and MU
(Memory Unit)
Arithmetic Logic Unit (ALU)
It does all the operation as per the
direction whether arithmetical or logical upon the data or information and send
that to memory unit from there the control unit sends back the result to the
output media through buses as per the user direction.
Control Unit
Decode
instructions and determines which is next to be executed. Control Unit is a
Part of the processor that is in-charge and it directs the computer system to
execute stored program instruction.
Memory Unit
In this unit, the data are stored during the
processing .Its speed is faster access then memory. Formally we call this
Registers too. It is far faster than memory while execution it is very near to
processor.
Bus
This is a path medium for information entering or exiting the CPU.
