What is CPU?
The full form of CPU is Central Processing Unit. It is a small but important part of the computer. Which is similar to a chip. It processes all the instructions of the computer and gets the result according to the program. After this the computer gives an output. That is, before getting the output in the computer, the work of the CPU is done. It controls and processes instructions. Only then is there a result.
CPU is a type of electronic device. But just as the mind of a man is necessary for a man. In the same way, the CPU of the computer is necessary for the computer. Because CPU is considered as the brain of the computer. Just as man can’t do anything without his mind. In the same way computers also can’t do anything without the CPU. Whatever you can do with a computer. CPU has an important hand in that. That’s why it is called the most important device of the computer.
To get the output of each input in the computer, it has to pass through the CPU. Let us take an example to understand it in simple language. As; You use Calculator Software to add two numbers to the computer. Then first of all with the help of a keyboard the computer will have to input two numbers. Now the keyboard Controller will convert those two numbers into Binary Language. This is because Computer works on Binary Language. When these two numbers reach the computer CPU. Then the main part of the CPU Arithmetical Logical Unit shows these two numbers on the computer display by adding them.
Similarly, the CPU is responsible for executing any type of work on the computer. Because by this all the work is executed. Because of which the CPU often gets hot. A fan is placed near the CPU to prevent the CPU from heating up. Which is called CPU Fan or Cooling Fan. CPU is also called Processor, Microprocessor and in short just CPU. Therefore, Processor Specifications of Computer System or Smartphone. It is made in such a way that thousands and millions of small transistors are installed in it.
Note:- CPU can access RAM and get data from it to process.

Functions of CPU
As we have already mentioned that CPU is the most important device of the computer system. Because its work is most prominent in the computer. Here we will known in detail what are the functions of Computer CPU and what CPU does in the computer.
· · CPU reads data by accessing memory to get input.
· · The CPU executes the instructions received from the computer keyboard.
· · The CPU controls and processes all the functions of the computer.
· · The CPU works on the basis of programs and instructions received from the computer.
· · The CPU received data from the input device and displays the result.
· · The CPU processes all the functions of the computer.
· · CPU performs arithmetic calculations and logical calculations.
· · The CPU converts Input into Output.
· · CPU connects Input Device and Output Device.
· · Simply put, all the work of the computer passes through the CPU. It acts as the brain for the computer.
Parts of CPU
As we said, CPU is the brain of the computer. It processes all the functions of the computer. Only after this the computer is able to show any result. Some of the major device of CPU help in performing these tasks of CPU. which are part of CPU. Each part of the CPU has its own separate function. Now you must be wondering how many parts are there in the CPU. CPU is mainly made up of three parts. Whose name is as follows.
1. · Arithmetical Logical Unit (ALU)
Arithmetical Logical Unit is abbreviated as ALU. It is the main part of CPU. It is responsible for performing arithmetic and logical operations. As; The processing of tasks like addition, subtraction, multiplication, division, comparison and yes or no is done by the Arithmetical Logical Unit, part of the CPU. Apart from this, selecting, matching etc. under logical work is also the work of this part of CPU. In general language, the work of ALU is to do Arithmetical Operations and Logical Operations.
2. · Control Unit (CU)
Control Unit is abbreviated as CU. It controls all the functions and events of the computer. Controls all the processes taking place in the computer. It receives instructions from computer memory. Apart from this, it creates coordination between all the Input Devices, Output Devices and Processors of the computer. Due to which the result of the instructions given by the Input Device is received on the Output Device. Since it manages all the operations of the computer. That’s why it is called the manager of computer.
3. · Memory Unit
Memory unknit is a storage device. Whose work is to collect the necessary instructions, programs, commands and result in the computer. It also an important part of CPU. To perform any task in the computer, the received instructions are first kept in the memory. After which instructions are received from the memory and processed. After processing the result is then kept in the memory. So that is then kept in the memory. So that user can use it anytime. Computer uses different memory to perform these tasks. Uses RAM to hold unprocessed instructions. Which is a temporary memory. Whereas processed instructions i.e. keeps the result in ROM. Which is a permanent memory. The data kept in this memory can last forever. Which can be used anytime.
How does CPU work?
CPU is the major part of computer system. This is that device. Which gives the result of the instructions given us. In such a situation, we must know how the CPU works. Since the work of the CPU is done by the peripherals of the CPU. We have explained above the function of CPU and its accessories. In which the work of ALU, the work of memory Unit and what is the work of Control Unit inside the CPU. If we talk about the way CPU works, then CPU works in three stages from taking instructions to giving results. The three phases of CPU work are Fetch, Decode and Execute respectively. Let us know these steps in detail.
1. Fetch
The first stage is Fetch. As its name suggests, instructions are fetched in this phase. Means it is received. These instructions are received from RAM to the CPU in the series of Binary Number. But the CPU does not receive any instructions directly from the RAM. Rather a large operation is divided into several smaller building blocks or sets. After which CPU receives each piece of instructions one by one. It has a Program Counter (PC) to find out the next set of instructions from these sets. Which tells the CPU which set of number to process next. Instructions after the first step are stored in a register called the Instructions Register (IR).
2. Decode
This is second step. In this, store instructions in IR are passed to the instructions decoder circuit. In which the Decode phase begins. Where the instructions are Decoded into Signal and interpreted. After the instruction is decoded into a signal, it is sent to another part of the CPU for further processing.
3. Execute
This is the last step. In this step the decoded instructions are executed. After which stores the result Obtained in the form of output in the CPU Register. So that other Decode instructions can give reference to them. After this, as per the requirement, the result is given to the Output Device or the internal memory is kept safe.
Types of CPU
When we talk about the type of Computer CPU. Then it refers to the capacity and speed of the computer CPU. The higher the speed of the CPU. He can do any work quickly. CPU speed is measured in Gigahertz. As; if the speed of a CPU is 3.0 GHz. Then it can process up to three billion instructions in a second. How fast will the computer system and software work? This part of the computer also depends on the CPU only.
Therefore it becomes necessary to choose the right CPU for your system. Which can handle the whole system properly. When we talk about the performance of CPU. Then it becomes very important to know what is Core in CPU. Means what is Core? Do you know what is Core? Today’s CPUs are divided into several sets. Each part of which is called a CPU Core. It tells the capability of the CPU Core. That is, if a CPU has a Core. Then that CPU will be able to do one task at a time.
Similarly, the CPU which will have multiple cores. He will be able to do multiple tasks at a time . the parts of Core are called Threads. How many tasks will the CPU do at a time? It depends in the cores and threads of the CPU. The earlier CPUs used to be single core only. But with time it developed and today CPUs with multiple cores come. Due to which multiple tasks can be done at a time. Here we have told about some types of CPU. So that it will be easy for you to know which CPU is best for your system. So let’s know how many types of CPU are there.
1. Single Core CPU
The CPU in which there are single cores. They are called Single Core CPU. That is, this CPU has the capacity of a processor. These are the oldest CPU types. Earlier this CPU had to be used. This type of CPU had ability to execute only one process at a time. That is, multitasking was not possible through this.
2. Dual Core CPU
Dual Core CPU has two cores. That is, the capacity of the processor is two in it. You must have seen Dual Core written in the specifications of Mobile or Computer. Which means from this CPU. It can do more tasks at a time than single core CPU. Its processing speed is also higher than Single Core CPU. But less than Quad Core CPU>
3. Quad Core CPU
A CPU with four cores is called a Quad Core CPU. It has the capacity of a four core processor. Due to which its processing speed is better than Single Core CPU and Dual Core CPU. Multitasking is possible with its help. Big tasks can be done easily with this type of CPU. As; Videos Editing, Designing, Games etc.
Hope you have understood the type of CPU. Earlier there used to be a single core CPU. But over time it evolved and today a CPU chip has Multiple cores. Which made multitasking possible. Above we have told up to four core CPU. But nowadays six core CPU called Hexa Core CPU and eight core CPU called Octa Core CPU. This too has started coming. That is, today more than one core has starts coming in a single CPU chip. But each CPU chip is made up of at least one core.

How made CPU
CPU is a type of Micro Chip. Which is made from Silicone Chip. Whose main material is silicone. Since silicone is available in large quantities in sand. That’s why sand is used to make semiconductor from sand, one has to go through two companies or two factories. In the first factory, Silicone is extracted from the sand. For this send is subjected to high heat (about 1000°c) and special type of chemical is used. After this process, silicone is obtained in the form of small crystals.
By heating these crystals, a special type of chemical is used to make a cylinder of silicone. This cylinder is called an ingot. Now this Silicone cylinder is tested whether it is Pure Silicone or not. When the cylinder of silicone is passed in the test. It is then divided into thin portions. Which is called Wafers. These Wafers are made smooth by cutting and polishing. Now these wafers are delivered to the chip making company or factory. Where many transistors (Millions of Transistor) are made on top of these wafers. Ultraviolet laser is used in this. When transistor is printed on these wafers.
Several chips are obtained from each Wafers. Finally these chips are tested. When everything is correct, it is packed inside a cover. All this process is not that easy. This can be gauged from the fact that all these processes are done at the microscopic level. That means we can’t even see with naked eyes. There are many other processes involved in this. But hare we have explained it in simple language and in brief. So that you can easily understand how CPU is made from sand.
