What is Processor and how does it work

At this present time, everyone is working on the computer but there are many people among them who do not know about What is Processor. If you also do not know about the processor, then by reading this article today, what is your processor? What is processor will be known.

How does the processor work in the computer? If we say in short words, Processor is a small chip living inside the computer or mobile that helps in controlling the computer, laptop, or any mobile device.

What is Processor?

A processor is a chip that is attached to the motherboard and processes the input and output operations inside the computer. It takes input from you, processes it, and then works to deliver the correct output to you.

From the time the computer is ON, the processor controls all the work being done on the computer. Usually, the processor is also called the CPU (Central Processing Unit) which is also called the brain of the computer. The speed of completing any work depends on the processor itself.

Purpose of the processor in the computer:

The purpose of a processor in a computer is to properly operate things inside the computer, such as maintaining memory storage, receiving input from the user and processing it, providing output to the user after processing, etc.

Nowadays people do more than one task in their computer at the same time to save their time, so due to this the work of Computer Processor becomes very complicated. The quality of a good processor is that it is able to easily manage more than one task simultaneously.

Processor History:

The Intel company was the first to invent the processor. The first single-chip microprocessor to come from Intel was the "Intel 4004 microprocessor" which was made by Intel's 3 engineers in the year 1971, if we talk about those Intel engineers, then that is Federico.

Faggin, Ted Hoff and Stan Mazo. Intel's first processor was very big in size compared to the processors of the present time, but as time progressed, we also got to see better and smaller processors, the processors we get to see today are similar to the earlier processors. Much faster than that.

How To Works Processor?

The processor is connected to the RAM of our computer and RAM is connected to the hard disk of our computer, whenever we want to process something, the data of that file is transferred from the harddisk to the RAM (RAM is a memory that holds the data of the computer).

Stores it only for some time and RAM is also called volatile memory) and then the processor decodes all the instructions of that data (any data can have many instructions) one by one.

The computer can understand only binary language, so the processor first changes the instruction from our language to binary language, which it can easily understand, this is called decoding.

After that, the processor works as per the instruction. There are many divisions inside the processor which are capable of doing different tasks. For example, there is an Arithmetic logic unit (ALU) that is capable of doing addition, multiplication, division, etc., and many more.

Finally, after the processor completes all its work, if something has to be stored, it sends it back to the memory or if something has to be displayed for the user, it displays it on the screen. The processor takes only a few seconds to complete these tasks. Generally, all processors work in almost the same way.

Types of Processor:

Processors are produced by many companies but most of them manufacture mobile processors. At present, two types of computer processors are more popular in the market:-
  1. Intel
  2. AMD
When Intel introduced its single-core processor (Intel 4004) in 1971, only one task could be controlled at the same time on the computer. But in 1993, when Intel introduced the Intel Pentium processor, both programs could be easily controlled at the same time in the computer program and after that gradually.

Intel brought more powerful processors into the market such as Intel Pentium, Intel Pentium 3, Intel Pentium 4, Intel Celeron Processor, Intel Core 2 Duo, Intel Core 2 Quad, Intel Xeon processor, and intel i3, intel i5, intel i7, etc.

As technology progressed, Intel and AMD also introduced new processors into the market. So far, many variants of these two have come on the market. The latest is Intel's Intel Core i9 processors and AMD's AMD Ryzen 9 3900X.

As the technology is progressing, the speed of the processor is also increasing. Therefore, we should buy the same computer or laptop in which the processor of the latest version is available.

What is the Core in Processor?

As you know that the speed of the computer depends on the processor itself. But let us tell you that the speed of the processor is also dependent on the core. The performance of the processor is usually estimated from the core itself. The more cores in a processor, the higher will be its speed. Core only shows the capacity of the computer.

If the CPU of any computer has only one core, then it means that the computer is capable of doing only one task at a time easily. If your computer's CPU has more than one core, it means you can easily do more than one task at a time. Today's CPU has multiple cores so that the computer can do more than one task easily and at a faster speed.

What is Clock Speed and Gigahertz?

The number of cycles your CPU completes in a second is called clock speed and is measured in gigahertz. The higher the clock speed of a computer's CPU, the faster that computer will work.

Therefore, while buying a computer or laptop, we should always keep in mind that how much Gigahertz is the clock speed of its processor and should always buy a computer with more GHz so that our computer works faster.

 Processor Generation in Computer?

Intel company every year launches a new powerful upgrade variant of the old processor, the same is called the generation of the computer processor. Earlier Intel did not launch Generation Wise by upgrading processors as much, but since 2010, Intel company is continuously upgrading its processors and bringing new generations such as –

Intel i3 1st generation
Intel i3 2nd generation
Intel i3 3rd generation
Intel i3 4th generation
Intel i3 5th generation
Intel i3 6th generation
Intel i3 7th generation

Note – The higher the generation of computer processor, the better the computer performance will be, that is why at the time of buying a computer or laptop, all of you will check whether the generation of a computer processor is the latest or not.
