WHAT IS PROCESSOR ?

WHAT IS PROCESSOR ?

CPU in VLSI(Very Large Scale Integration) technology is called micro processor or processor.

Processor is made up of silicon material.

Processor's main function is to process the data and produce in the standard format. 

On the Motherboard where the processor is located it's called Processor Socket. 

It process the data given my program.

Processor works on instructions.

When the processor was processing the data it will become hot. to keep the processor cool there was a cooling gel layer on the processor where we can apply cooling gel. also there was a fan on processor to bring out heat. 

Processor Layers :

The processor work is devided in three layers. 

- ALU

- MU

- CU

1. ALU :-

ALU fullform is Arithmetic Logic Unit. 

This is first step of the processor. where arithmetic and logical operations are done. The ALU operates the data available on the main memory and send them back to main memory after processing. ALU performs on the operations on the data provided by Input Devices. (Check Here What is Input-Output Devices- What Is Input-Output Devices)

2. MU :-

MU Means Memory Unit. 

Memory Unit's main function is to store the instruction while processor is busy in his process. Once the CPU has carried out an instruction, its important to store the result.

the storage capacity is generally measured in megabytes.

Some Storage Measurements :-

8 bit = 1 byte
1024 bytes = 1 kilobyte (KB)
1024 kilobytes = 1 megabyte (MB)
1024 megabyte = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB)
1024 terabytes = 1 petabyte (PB)
1024 petabytes = 1 exabyte (EB)
1024 exabytes = 1 zettabyte (ZB)
1024 zettabytes = 1 yottabyte (YB)
1024 yottabytes = 1 brontobyte (BB)

3. CU :-

CU Is Control Unit. It is used to control the instruction. the control unit coordinates the activities of all other units in your computer system. control unit's main function is to control the transfer of data and info. between different units.
