What Is Processor and How It Works?
Do you know what is this Computer Processor? Whenever we talk about a computer, the matter of Processor definitely comes in our mind. A computer is not possible without a processor. Yes, it is definitely right that if the efficiency of a processor is low, some of it is more. But having a processor is mandatory for all computers. It is also known as CPU, central processor and microprocessor CPU i.e. its full form is Central Processing Unit. Like this, it is the brain of a computer that keeps an eye on all the activities. He handles all these instructions that he gets from hardware and software. If seen, it is basically a hardware that does all the calculations very quickly, when it gets some input, then processes it and after doing some calculation, the result comes out.
But do you know how this small thing alone processes so much information? So today we want to give some information to you people in this article What is Processor and how it works. Then what is the delay? Let’s start.

What is the Processor?

processor is an essential part of the computer. You can also say that a processor is like the brain of the computer. This is because the news of all the activities happening inside the computer is near it, so it says that it controls all these things. Trillions of processing can be done at one time. By understanding the interpretation between software and hardware, it processes and gives us the output. It is inside all the devices like Mobile, Tablets, Personal Computers, Laptops. It is also known as CPU.
It is a square-shaped device in appearance, from which many metallic, short and rounded connectors are lowered out. It is attached to the CPU’s Socket itself. After running for a long time, it becomes slightly hot, that is why a heat sink and fan is put on it to release the heat. It is a very delicate thing, due to which it is carefully placed in the motherboard. They come in many types such as Intel’s Processor i3, i5, and i7.

History of Processor

Intel first designed the first single-Chip Microprocessor in the world in 1971. Processors were invented by three Engineers of Intel, whose name was Federico Faggin, Ted Hoff and Stan Mazo. This chip, named Intel 4004 Microprocessor was designed in such a way that all the processing functions like CPU, Memory and Input and Output Control were placed in a single chip. Gradually, new innovations took place over time, which led to a lot of change in the design of the computer. Their capacity to work increased and their size decreased. Now, Intel is the leader of the world of Processor. They make Processor of every variety according to the needs of the people.

What does CPU do?

The CPU basically has three basic functions, first it takes information, second, it performs some operations on it and third it gives results after calculation. But to do these three processes it has to use some key components. ALU (Arithmetic and Logic Unit) subtraction and addition in binary. Along with this, they also do some logical operations like AND, NOT and OR, to help the CPU. Control Circuit directs data traffic from CPU to slower Input / Output devices, so that traffic can be exchanged. The Memory Management Unit monitors the flow of data to and from Memory.

Types of CPUs

What is Processor in Hindi There have been many types of CPU inventions in the last few years. As time went by, so did new CPUs as per the requirement. Earlier the number was used to identify the processor. Ever since Intel has released the Pentium Processor (technically these are 80586), the processors have been named like Athlon, Duron, Pentium, and Celeron.
Nowadays, their architecture has changed along with the name, from now on, Processor with only two types of Architecture is used a lot like 32 Bit and 64 Bit. Due to this architecture, now the speed and capacities of the processor have also increased significantly. Processors such as AMD Opteron series and Intel Itanium, Xeon Series, are used in servers and high-end stations. And if we talk about small devices like Smart Phones and Tablets then they use ARM Processor. These processors are smaller in size than normal, they require less power and they produce very less heat.

What is the clock speed of the processor?

It is also known as clock rate and processor speed. Clock speed is called the speed at which the microprocessor executes each instruction or each vibration of the clock. Since the CPU needs a fixed number of clock ticks or cycles to execute each instruction. So the faster your clocks rate, the faster your CPU will be, or the faster your processor can execute instructions.
What Is Processor and How It Works?
Clock speeds are measured in MHz, 1 MHz means 1 million cycles per second or GHz, 1 GHz means 1 thousand million cycles per second. In a general sense, then the higher CPU speed, the better your computer will perform. Computer speed also depends on other components such as RAM, hard drive, motherboard, and number of processor cores (such as dual-core or quad-core).
Speed of CPU indicates that how much calculation can be done by it in one second. The higher the speed, the more calculations it can perform, which will make your computer run even faster. Different brands of computer processors are available in the market, such as Intel and AMD, but they all follow the same CPU speed standard, so that it can be known which speed the processor runs.

What is Core in Processor?

Processors have different cores according to their capacity. A common processor has a single-core, ie it is a single CPU. The Dual Core The processor consists of two processor circuits with two identical frequency. It can work at double speed as compared to Single Core Processor that too easily.
Currently, there are many different Core Processors available in the market such as: –
2 Core in Dual Core
4 Core in Quad Core
6 Core in Hexo Core
8 Core in Octa-Core
10 Core in Deca Core
The more Core the processor, the more successfully it can complete multitasking.

How Processor Works

The design of the processor is much more complex than the common design, and they vary greatly from company to company, even one model is quite different from the other. Right now the processor of two companies like Intel and AMD are in great demand in the market. These two companies are always engaged in trying to make how to improve the performance of the processor by using less space and energy. But despite having so many architectural differences, the Processor mainly has to go through four processes, and only then can they process the instructions. These four processes are known as fetch, decode, execute and write-back. Now I will tell you about all these processes.
1. Fetch
Fetch as if it means bringing something. Here the Processor retrieves the core instructions that remain in waiting in a memory. But in today’s Modern Processor, usually, those instructions are already waiting in the Processor Cache. The Processor has an area called Program Counter which acts like a bookmark, informing the processor about where the last instruction ended and where the next one started.
2. Decode
Once the instruction Fetch is done then the next process is to decode it. There are many areas of processor core in an instruction such as arithmetic and which the processor core has to recognize. There is also something in each part called Opcode which tells the processor what to do by using that instruction. Once the Processor recognizes what he has to do, then he does all the things on his own.
3. Execute
In this step, the Processor knows what he has to do, and he actually makes him executive. What actually happens here depends on what area of ​​Processor Core comes in use and what information is put into it. It is believed that this operation takes place within ALU. This unit is connected to other inputs and outputs so that it can simplify its work and finally give us our results at the right time.
4. Writeback
This step can also be called, as its name is, its work is also the same, which places the result of all the three previously done tasks in the memory in memory. To find out where the output has gone in Aakir, it depends on which application is running at that time. But it is usually in the register of the processor itself because it is very much needed, then it is kept here for quick access.
This entire process is called Instruction Cycle. As we are progressing, we are also having better processors which are very fast and powerful. Our CPU is designed in such a way that it divides many tasks so that it can process as quickly as possible. And with new inventions, it seems absolutely possible.

Conclusion

In the near future, we will get to see even better Processor. Because nowadays companies of all processors are paying more attention to how to design such processors in a short time that can be operated in less space and less power. And it should be more efficient. If we compare the processors of earlier times with today’s design, then we have become successful in this mission to a great extent and hope that in the future we will be able to create even more efficiency processors.
