How does work Processor ?
Yes, it is definitely true that if the efficiency of any processor is less, then some have more. But it is mandatory for all computers to have a processor. This processor has many names such as CPU, central processor and microprocessor CPU i.e. its full form is Central Processing Unit .
In other words, it is the brain of a computer which is keeping an eye on all the activities. It handles all these instructions which it gets from Hardware and Software. If seen, basically this is such a hardware that does all the calculations very quickly, when it gets some input, then processes it and after doing some calculations the result comes out.
But do you know how this small thing can process so much information alone. So today we want to give some information to you people in this article, what is Processor and how it works. Then what's the delay, let's start.
What is Processor ?
Processor is a very important part of computer. It is also called the brain of the computer. This is because it has the news of all the activities happening inside the computer, that is to say, it controls all these things. It can process trillions of calculations at a time.It understands the interpretation happening between software and hardware and gives us output by processing it. This happens inside all the devices like Mobiles, Tablets, Personal Computers, Laptops. It is also known as CPU .
It looks like a square shaped device, which has many metallic, short and rounded connectors protruding from the bottom. It is attached to the socket of the CPU itself.
After running for a long time, it gets a little hot, that's why a heat sink and fan is placed on it to drain the heat. This is a very delicate thing, due to which it is fitted with great care in the motherboard. These come in many types such as Intel processors are i3 , i5 and i7 .
History of Processor ?
Intel designed the first single-chip microprocessor in the world in 1971 . It was invented by three Intel engineers Federico Faggin, Ted Hoff and Stan Mazo.This chip, which was named Intel 4004 Microprocessor , was designed in such a way that all the processing functions such as CPU, Memory and Input and Output Control were kept in a single chip.
Gradually, with the passage of time, new inventions took place, due to which there was a lot of change in the design of the computer. Their working capacity increased and their size decreased. In today's world, Intel is the king of the processor world. They make processors of every variety according to the needs of the people.
what does cpu do
CPU basically does three basic things, first it takes this information, second it does some operation on it and third gives result after calculation. But to do all these three processes, it has to use some key components.ALU (Arithmetic and Logic Unit) performs subtraction and addition in binary. Along with this, they also do some logical operations like AND, NOT and OR to help the CPU.
Control Circuits direct data traffic from the CPU to slower Input/Output devices, so that traffic can be exchanged and distributed. The Memory Management Unit monitors the flow of data to and from memory.
Type of cpu
Several types of CPUs have been invented over the years. As time passed, new CPUs kept coming according to the requirement. Earlier the number was used to identify the processor.
For example, Intel 80486 (486) processor is much faster than 80386 processor. Ever since Intel released the Pentium Processor (technically these are the 80586) processors, the names of the processors are as follows: Athlon, Duron, Pentium and Celeron.
Nowadays, along with the name, their architecture has also changed, generally, processors with only two types of architecture are used a lot like 32 Bit and 64 Bit . Due to these architectures, now the speed and capabilities of the processor have also increased a lot.
Like AMD Opteron series and Intel Itanium, Xeon series processors 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 generally smaller in size, require less power and generate very little heat.
Since the CPU needs a fixed number of clock ticks or cycles to execute each instruction. Therefore, the faster your clocks rate, the faster your CPU will be, or the faster your processor can execute instructions.
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, the higher the 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).
This CPU speed shows how many calculations it can do in 1 second. The higher the speed, the more calculations he can perform, so that your computer will run faster.
There are different brands of computer processors 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 processor runs at what speed.
At present, there are many different core processors available in the market such as :-
Dual Core in 2 Core
Quad Core in4 Core
Hexo Core in 6 Core
Octa Core in 8 Core
Deca Core in 10 Core
The more cores the processor has, the more successfully it can complete multitasking .
These two companies are always trying to improve the performance of the processor, that too by using less space and energy. But despite having all these architectural differences, the processor mainly has to go through four processes, and only then can they process the instructions. These four processes are fetch, decode, execute and write-back . Now I will tell you people about all these processes. ,
But this is usually done only in the register of the processor because it is needed very much, so it is kept here for quick access.
This whole process is called the Instruction Cycle. As we are progressing, we are getting even 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 be processed as quickly as possible. And with new inventions it seems quite possible too.
I have full hope that I have given you complete information about what is Processor and how it works and I hope you people have understood about this computer term. I request all of you readers that you also share this information in your neighborhood, relatives, your friends, so that there will be awareness among us and everyone will benefit a lot from it. I need your cooperation so that I can pass more new information to you guys.

What is the clock speed of the processor?
This clock speed is also called clock rate and processor speed. Clock speed is called the speed with 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. Therefore, the faster your clocks rate, the faster your CPU will be, or the faster your processor can execute instructions.
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.

What is Core in Processor?
Processors have different cores according to their capacity. A normal processor has a single core, that is, it is a single CPU. Whereas Dual Core Processor consists of two processor circuits with two identical frequencies. It can work at double speed as compared to Single Core Processor, that too very easily.At present, there are many different core processors available in the market such as :-
Dual Core in 2 Core
Quad Core in4 Core
Hexo Core in 6 Core
Octa Core in 8 Core
Deca Core in 10 Core
The more cores the processor has, the more successfully it can complete multitasking .
| DESKTOP | Core i3 | Core i5 | Core i7 |
| No. of cores | 2 | 4 | 4 |
| Frequency range | 3.4-4.2GHz | 2.4-3.8GHz | 2.9-4.2GHz |
| Turbo Boost | No | Yes | Yes |
| Hyper-Threading | Yes | No | Yes |
| Cache | 3-4MB | 6MB | 8MB |
How Processor Works
Processor designs are generally quite complex, and they vary greatly from company to company, even one model differs greatly from the other. Right now the processors of two companies like Intel and AMD are in great demand in the market.These two companies are always trying to improve the performance of the processor, that too by using less space and energy. But despite having all these architectural differences, the processor mainly has to go through four processes, and only then can they process the instructions. These four processes are fetch, decode, execute and write-back . Now I will tell you people about all these processes. ,
1. Fetch
Fetch as in it means to fetch something. Here the processor retrieves the core instructions which are waiting in some memory. But in today's modern processors, usually those instructions are already waiting in the processor cache. There is an area in the processor called Program Counter which works like a bookmark, which informs the processor where the last instruction ended and where the next one started. ,2. Decode
Once the instruction is fetched then the next process is to decode it. There are many areas of the processor core in an instruction such as arithmetic and which have to be recognized by the processor core. There is also something in all the parts which is called Opcode which tells the processor what to do by using that instruction. Once the processor recognizes what it has to do, then it automatically does all the things.3. Execute
In this step the processor knows what to do, and he actually executes it. What actually happens here depends on what area of Processor Core is in use and what information is put in it. For example, the processor uses ALU to perform any arithmetic operation. Assume that this operation takes place within the ALU itself. This unit is connected to other inputs and outputs so that it can make its work easier and finally can give us our result in the right time.4. Writeback
This can also be called Aakir Step as it is named, its work is also similar, which places the result of all the three tasks done earlier in Aakir in memory. Finding out where the output went in Aakir depends on which application is running at that time.But this is usually done only in the register of the processor because it is needed very much, so it is kept here for quick access.
This whole process is called the Instruction Cycle. As we are progressing, we are getting even 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 be processed as quickly as possible. And with new inventions it seems quite possible too.
Processor Information
In the near future, we will get to see even better processors. Because nowadays all processor companies are paying more attention to how they can design such processors in less time, which can be operated in less space and less power. And it should be more and more efficient. If we compare the earlier processor with today's design, then we have been successful in this mission to a great extent and hope that in future we will be able to make processors with even more efficiency.I have full hope that I have given you complete information about what is Processor and how it works and I hope you people have understood about this computer term. I request all of you readers that you also share this information in your neighborhood, relatives, your friends, so that there will be awareness among us and everyone will benefit a lot from it.
