What is Processor and Types of Processor

Hello Guys in previous post of Hardware Learning we have talk about the BIOS. In this Post we are going to deal about Processor. Processor is another essential hardware component of MOTHERBOARD for computing the instruction and to process the output.

Processor: A processor is the logic circuitry that responds to and processes the basic instructions that operate a computer. The four core functions of a processor are to fetch, decode, execute and write back. 

Processor Era
In 1990s we used to get Chipset processor that is fixed with MOTHERBOARD and cannot be removable. Those processor are like 8085, 8086, 8088. After these processor we used to get Pin Processor.
There are list of processor:
  • Celelron -----------> Pin processor
  • AMD---------------> Pin Processor
  • AMD Athelon-----> Pin Processor
  • Pentium I-----------> Pin Processor
  • Pentium II----------> Pin Processor




  • Pentium III-------------
  •                                    |-----------> Pin Processor and Slot Processor
  • Pentium IV-------------


Note-> Slot processor looks like a RAM slot card that is very bad model and closed their production in 3 months only. From Celeron on wards processor are coming with Pin design

Core Model
From Core Model, processors are coming with two design 1. Pin Processor and 2. Pinless Processor also known as Dot Processor.

What is Core Processor?
Core is the Heart of the Processor that is located in the middle of the processor. Each core contains four layers and each layer works separately. Processor contains 3 units which are most important part of it. Every unit is separated and has their different task to perform.
These three units are 
  • PU-> Processing Unit
  • CU-> Control Units
  • ALU-> Arithmetic Logical Units


 Let's start from ALU- Any request coming from operating system first goes to RAM and then ALU. It takes specified amount of data and converts it into machine language that is binary format ad perform the required asthmatic and logical operation. This is the specific task of ALU. ALU is again used to Decode the binary data in human readable format when it works revers order.


Now CU act as a controller and it controls data speed or flow. Controller has less work but responsibility is there. If CU gets confused then system will definitely hang. In this case re-start or shut down your computer and start again. CU sends binary data to PU units.

Here PU (Processing unit) will take data from CU (Control unit) and converts in Bit format and specify headers and tailor with data to identify. In additional data those are like file no, serial no. and no. of character. After adding those data, they compress it and forward it to the hard disk to write on disc.
     

  • Core 2 Dual---->Single Core Processor
  • Dual Core   ----> Double Core Processor




In Dual core processor, each core works as a separate processor and that is logical partition. the benefits of dual core is speed the process and save more time. each core equally divide the task and produce result faster.  

Generation Processor
  • i3-------> Dual Core
  • i5-------> 4 to 6 Core
  • i7-------> 6 to 8 Core


Server processors works on Multi Core Processor and each core contains separate ALU, CU and PU.
