What is cpu? How cpu works, cpu full form, cpu full form


Today in this post we Central Processing Unit (CPU) Details related to What is cpu, types of cpu, components of cpu, full form of cpu, tasks of cpu, how important cpu is, etc. We are going to tell you the details of all the information from the CPU in this post. These days computer The use of is increasing. In earlier times computers were not used that much. But in today’s time, computer has become an important part in people’s routine.

Computers consist of many different parts. A major part of the computer CPU is. Whom computer Brain it is said. This part of the computer processes all the processes of the computer. CPUs play an important role in computers. About CPU modern technology has made people’s lives easier and more comfortable. Clocks have been logged to perform our first work, now we can use technology to do our work in lunar moments.

When computers were invented, there was almost a revolution in the computer world. Many people also use personal computers. We sit in several rooms with computers. Computers have become an important part of Roger’s life. It is impossible to run a computer without a CPU. CPU plays an important role in all types of activities on a computer.

Today in this article What is cpu and how cpu worksyou CPU It is very important to have complete information that you are going to get in this article. After reading that, you can choose a good CPU for yourself. The complete information of the CPU is stated in Hindi. So, definitely read the post.

What is CPU (Central Processing Unit)? What is CPU in Hindi

Central Processing Unit (CPU) Is a component of a computer system that is usually “Brain” is referred to as. Processor or Microprocessor is also known as CPU. A sequence of stored instructions known as a program is executed by the CPU.

The CPU is an important part that manages all instructions and calculations that are sent to it from other computer components and peripherals. Even the speed with which a software program runs depends a lot on how powerful the CPU is.

Definition of CPU: Central processing unit (CPU) is the central component of a computer system. Sometimes it is called a microprocessor or processor. It is the brain that runs the show inside the computer. All tasks and processes performed on the computer are performed directly or indirectly by the processor. Obviously, a computer processor is one of the most important element of a computer system.

CPUs consist of transistors, which receive input and produce output. Transistors perform logical operations called processing. It is, scientifically, not only one of the most amazing parts of PC, but also one of the most amazing devices in the world of technology.

What is the full name of CPU (CPU Full Form in Hindi)

The full name of the CPU is ‘Central Processing Unit’. The CPU is called “Central Processing Unit” in Hindi.

CPU: Central Processing Unit

The full form of CPU is Central Processing Unit. Also known as Processor and Microprocessor. It is also known as the brain of a computer because CPU is the hardware of the computer and Software Handles all instructions received from. It receives data and instructions from input devices, processes it, and returns results. The computer provides the processed information back to the users using a special output device.

CPU components – Component Of CPU

The Central Processing Unit has the following features –

  1. The CPU performs all types of data processing tasks.
  2. It saves information, intermediate results and instructions.
  3. The CPU monitors the performance of all computer components.

The CPU consists of the following 3 components –

  1. Memory or storage unit
  2. Control unit
  3. Arithmetic Logic Unit

Types of Central Processing Unit (CPU) – Types of CPU

The two competing manufacturers of CPUs are Intel and AMD, and each has its own variant of CPU.

Single Core CPU

The oldest type of CPU is the Single Core CPU, and it was initially the only CPU type that could be used on a computer. Single Core CPUs can only start one task at a time, so multitasking was not very successful.

This means that output degradation was noticeable every time more than one application was running. Since only one operation could be started at a time, the second could be started before the first one was done but the machine would run slowly with each new operation.

Dual Core CPU

Dual Core CPU processors have two main CPUs and hence function like Dual Core CPUs. In comparison, if more than one operation is performed, the Dual Core CPU can perform many tasks more effectively, whereas in a single core CPU the processor has to move between different data-stream sets.

To optimize the use of Dual Core CPUs, a special code, called SMT (simultaneous multi-threading technology), needs to be applied to the operating system and the programs that work on it. Dual Core CPUs are much faster than processors, but not as fast as quad-core CPUs.

Quad core cpu

Quad Core CPUs are multi-core CPUs with four cores on one core. Like a two core CPU, quad cores will break the workload between the fourcores, so a lot of work is done with the quad.

Each core is connected to other circuits inside the chip, such as cache, memory and I / O port management. Such CPUs are beneficial for those who need to run multiple programs simultaneously for gamers.

What happens inside the CPU?

CPU Hardware There is an integrated circuit at the level, also known as a chip. The integrated circuit “integrates” billions of small electrical parts, placing them in the circuit and all in a compact box. The CPU is normally a ceramic 2 inch square and is placed in the CPU socket with a silicon chip.

The central circuit board is the motherboard. It is a thin board that carries CPU, memory, hard disk connecting and optical drives, video and audio expansion cards simultaneously.

How does the Central Processing Unit work?

The CPU input uses the output device to process the instructions received from the device and provide the required output.

The main functions of CPU are-


First, the CPU receives instructions from program memory. Program memory is the location of the instruction. This location also stores a number that is the address of the next instruction that needs to be fetched.

After the instruction is received, the duration of the program increases to the duration of the instruction, so that it includes the address of the next instruction in the sequence.


The execution phase is followed by the steps of fetch and decod. This step can be single or composed of a series of actions, depending on the CPU electrically.

During each action, different parts of the CPU are electrically connected, so that they can perform the desired activity. The execution results are then updated in the internal CPU register.

How important is CPU?

The CPU is not as important to the overall performance of the system as it once was, yet it plays a major role in running the computer. Since it is fully responsible for executing commands within the program, the faster the CPU runs, the faster other applications run.

A Fast Processor does not have everything. A Processor cannot easily create the latest 3D game, no matter how powerful it is, nor can it store data. This is where other components come into existence, such as graphics cards and memory.

Simply put, CPU is not everything, but it is extremely important. Usually, speeding up the CPU will mean faster running of your machine or computer. Multiple threads and cores will help you create more stuff together.


In earlier computers, CPUs were made up of vacuum tubes and electric relays instead of microscopic transistors on computer chips. These early computers were much larger than today’s Microprocessor-driven computers and required much more power.

The first general purpose Electronic Computer, ENIAC, was introduced in 1946 and a large room was filled. About 18,000 Vacuum tubes were used to manufacture ENIAC’s CPU and input / output circuits.

Between 1946 and 1956 all computers had huge amounts of CPU consuming large amounts of energy consumption and constant maintenance, as vacuum tubes often burned out and had to be replaced.
