what is cpu and how does it work?

Computer is a machine that is used everywhere, but do you know how the computer whose Demand is so high, how does it all happen that whenever we have any information When filling with the Input Device, we get its Output or whatever work is done by the computer, how are all those who do it.Whenever a user gives Input, it takes only a few seconds to get his answer, but whatever process is done between the Input Device and the Input Device, it is the CPU and it is so fast. If the user does not even get a chance to think between it, then let us know what is the CPU? how does it work-

What is CPU?
The CPU also called the Central Processing Unit / Central Processing Unit is the part of the computer that shows all the information entered by the Input Device to us, and how to do a Calculation to show not just Show. That calculation was done and in the same way many processes are not visible to a human being.

A computer can do many things which may be a person has a lot of difficulty in doing, but it is easy for a computer. Calculation of a computer to be workable or any work is done in the computer's brain and what is called the brain of the computer is the CPU.

Calculation of a computer, or all the computer devices that work together, is also related to the CPU because the CPU keeps all these devices connected. Talking about the main part of the computer, the CPU is the part that is main in the computer. All these actions are just like how a creature controls all its organs through the brain.

How CPU Works?
Any CPU mainly performs 3 processes which is in this way, first of which the CPU checks the information taken by the input device, in the second process, the data is processed with the data inputted by the CPU. What type of Calculation is to be done and the result that occurs after this is shown in the output device. Whatever work a computer does, it definitely has three processes.

CPU history:-
In the beginning, the size of the CPU was very large, which could be even in the size of a room, but with the development of computers, the size of the CPU started decreasing with the generation, and the CPU which we all use today It can be easily moved from one place to another.

Earlier the CPU consisted of a vacuum tube which would heat up very quickly which also used a cooling fan to cool it and due to this the size of a CPU also became very large, after that the CPU started using transistors. And its specialty was that it did not heat up quickly and the CPU size was much lower than before.
Moving ahead of technology, Micro Processor started being used in place of transistors and due to this, the size of the computer was reduced very much. Because the size of the Micro Processor was so small that it could be easily caught in the hand.

CPU Functions:-
Whatever work a computer does, all of them are completed by the CPU. In this, connecting all the devices and which command to use on which command is also the work of the CPU. The CPU first receives any information, after this, it is processed according to the given command and its result is displayed on the output device.

Internal parts of CPU:-
A CPU consists of many parts and a CPU is made up of all of them. If the body is talked about in the CPU then ALU, CU, Memory are kept in the body. Apart from this, there are also some other parts in the CPU.

ALU (Arithmetic logic unit):-
All the calculations or logic functions in a computer are complete in all ALUs. The speed of its work is so quick that we get the answer in no time. Whatever arithmetic calculations are done in a computer such as addition, occurrence, multiplication, division or any argument such as matching or any kind of comparison, all these tasks are done by ALU.

CU (Control Unit):-
Many devices are connected together on the computer, some of which are Input Device and some Output Device. All these devices are controlled by the Control Unit. This means that when there is a process, by which device will this process be completed or done, it is the work of the Control Unit.

The job of SMPS switch mode power supply is to provide current to all the devices in the CPU. Current is required to use a computer, apart from Processor, Cooling Fan, DVD Player in the CPU, there are many components and it can do all the right things only when the appropriate current is given to them to use.If told in easy language, it is the task of SMPS to provide current to any component that uses current, which provides only as much current as needed to any component.

All the components that are installed in the CPU are connected to the Mother Board, the Mother Board is the Circuit Board, which includes many transistors, besides the processor, primary memory, external device slot, hard disk, etc. is. If the CPU is seen, a lot of slots or ports are given in it from different sides, but all these slots are connected on the motherboard itself.

The processor is the main part of any CPU because whatever process is in the computer is not possible without all Processor. The processor is used to do any type of computer work, even if it is a small task. The processor gets hot to perform any operation.
A Cooling Fan is also installed in the computer to keep the processor cool, which throws out the hot air from the Processor heating and tries to keep the Processor cool. In view, the Processor is like a small chip but the work done by it is the highest.

Primary memory:-
Whenever a user enters the data, it stays in the Data Primary Memory and it keeps the Temporary Save in the Data Primary Memory until its Result or Output is shown, and this is why the data of the Input device is shown to us. Primary Memory is of two types RAM and ROM.

Ram (Random Access Memory):-
Random Access Memory is a chip on the computer which is only part of the primary memory of the computer, it has the power to store the data for some time, but the data cannot be saved in it. The size of the Ram is less than the External Storage Device, but the speed of its working is greater.

Whenever the user uses the computer, the user also often processes some anal which uses Ram as if you have thought that whenever a text is copied, it is called Text Store, or very often When we do not save a file and close the software and when we open it again, we get the previous file when it was not saved and the reason is that all this is stored in the Data Ram itself. Because it is a temporary memory Data is saved for some time only.

When any software is opened on the computer, it is able to process itself through Software Ram, and if a lot of software is used in the computer simultaneously, then it also affects Ram, which causes Speed ​​Slow of the computer. There is a problem like being. GB is used for the size of a Ram. Ram is used for 16mb, 32mb, 64mb, 128mb, 512mb, 1Gb 2Gb, 4Gb size.

Rom (Read Only Memory):-
Read-Only Memory means ROM which is used as primary memory, you will know about ROM that we can only read whatever data is in it, we cannot change or delete that data. Even if you close the system, there is no effect on the store data in it, it remains the same when you open the data system.

The programs which are already stored in the computer are stored in all ROMs because these programs are kept away from the user, hence they are kept in ROM. If the user makes some changes in this program too, then there can be a problem like a system breakdown.

Hard disk:-
In the use of a computer, the task of Hard Disk is to store the data and it is also connected to the CPU which keeps the user by saving the data and the user can manipulate this data. Any operating system that is used on the computer is also stored on the Hard Disk.

CPU maker:-
Although there is a lot of CPU making company, but here you are being informed about some company which is known for manufacturing CPU -
• Intel
• Sun microsystem
• NTC Module
Friends, hope that you have got information about how the CPU works, if you want to ask any question related to this article, then you can ask your question in the comment.
