What does CPU stand for and What are the 3 different types of CPU?

Do you know What does CPU stand for and what are the different types of CPU? Why is it called the brain of the computer? If you are looking for answers to all these questions then there is no need to worry. In this article, we are going to answer these questions and provide complete information about CPU. So read the entire article

Just like there are many organs in our body and these are controlled through the brain, similarly, all the devices engaged in the computer are controlled by the CPU.

As technology advances, better technology is being used to make better CPUs. So that it can do even the most difficult tasks easily. The way to identify a CPU is by how much work it completes in a given amount of time. The CPU that processes and executes a task as quickly as possible is called an efficient CPU.

CPU is the most important thing in a computer because without a CPU the computer is nothing. Usually, it is called a processor or microprocessor. If you want to process your computer faster, then you have to install a fast-working processor on your computer.

There are different types of processors available in the market today. The more technology the CPU has, the higher its cost. However, some people are not aware of this, due to which they are not able to buy the specifications of the computer they want to use. That’s why it is important to have knowledge about the CPU.

If you do editing, graphics design, or any multimedia type of work, then you should take a computer with high specifications. So today in this article we will tell you all What does CPU stand for, function of CPU, the types of CPU and the 3 components of CPU in a computer. So let’s start without delay.

What does CPU stand for?

CPU stand for Central Processing Unit. It controls all the internal and external devices and parts installed in the computer. In general, a computer takes instruction input from the user and processes it by the CPU. After that produces the result on the output device.

CPU is also called processor or microprocessor. It is made up of many transistors and ICs. Therefore, it can easily do any complex task. Today’s CPUs have the ability to process multiple instructions at a time. It is also called multitasking.

Central Processing Unit

It is not wrong to call the CPU the brain of the computer because it solves the logical, arithmetic operation given to the user.

For example, you give instructions through the keyboard or mouse on the computer. The CPU converts that instruction into its own language i.e. binary language. It then processes the instruction and shows the results to the user.

Types of CPU

Usually, CPUs come with 3 types of sockets. Some have pins, some pads, and some balls.

  • Land Grid Array (LGA)
  • Pin Grid Array (PGA)
  • Ball Grid Array (BGA)

Land Grid Array (LGA)

Land grid array CPUs do not have pins. Chips are used in its lower layer which is like a square. It is used in that type of motherboard which has pins and it starts working once it is connected to that pin correctly. Such processors are used in the new generation of Intel processors.

types of CPU

Land Grid Array CPUs are currently built for desktops. It has a lot of pads. For example, 7th-generation CPUs have 1151 pads. In the 10th and 11th generations, processors have 1200 pads. In the 12th generation processor, there are 1700 pads.

Pin grid processor

Full form of PGA id Pin Grid Array CPU. For this types of CPU, there is a socket motherboard with separate holes. The Pin Grid Array technology is mostly AMD processors. It mostly has a 1331-pin processor.

Ball Grid Array (BGA)

Ball grid Array

Processors with a ball grid array have multiple balls. These ball grid array processors come with a motherboard from the company. That’s why it is called an onboard processor. This processor can simply be replaced or removed. The process to repair this processor technique is called reballing.

Functions of CPU

The most important thing in a computer is the CPU, it gives instructions to all the parts of the computer and uses it properly. So know what is the main function of CPU in the computer.

There are many parts to a computer. Some of them are input and some are output devices. So at all times a user interacts with the input device and provides instructions to the computer.

The computer stores that instruction in a storage unit. After that CPU accesses that instruction with the help of RAM and processes it. When the CPU executes after processing that data, it displays the result through the output device.

What are the components of CPU?

CPU controls all the processes happening in the computer. In this, the CPU is helped by some of its main parts. Now this question must have come to your mind What are the components of CPU?

There are 3 components of CPU. All of them had different jobs. So let’s know about these parts

  • ALU (Arithmetic Logic Unit)
  • Control Unit
  • Storage Unit

ALU (Arithmetic Logic Unit)

ALU is also called core. Therefore, the word core is used in the name of any processor. The higher the core performance of the processor, the higher its processing capacity of it.

The Arithmetic Logic Unit is made up of two sections. One is the Arithmetic section and the other is the Logic section.

Arithmetic unit

All types of arithmetic operations are done in this arithmetic unit. Just as the functions of addition, subtraction, multiplication, division, etc. are processed a bit. With this, the complex operation also becomes easily solved.

Logic unit

In this, logic operations such as selection, matching, compressing, or merging data are done.

Control Unit

This control unit controls all the functions of the computer. Its main function is that it decodes the input instructions and sends them to the ALU unit. It controls all the devices installed in the computer and coordinates between them.

It receives data from the storage unit and allows it to be processed. When the data is processed, then it stores it in the right place. This unit does not process the data nor does the work of processing the data.

Storage unit

The storage unit stores the information of all the operations taking place on the computer. This unit provides data or information to all other units. There are two types of storage units in this, primary storage and secondary storage.

The primary storage is required while the CPU is processing any data. The primary storage stores the data while the data is being processed. It stores the data inside itself for some time only.

Secondary storage keeps any data stored permanently. It keeps that data in a sequential manner which can be easily searched whenever it is needed.

How does a CPU work?

You must have come to know by now what the CPU does. In today’s date, many processors have been introduced. You must be feeling that all the different processors do different things. but it doesn’t happen.

The more expensive or the more technology or the less technology the CPU does the same thing. The working capacity of these can be more or less. All CPUs work in only 3 ways. It involves the process of fetching, decoding, and executing.

Fetch

In computer language, fetch means to extract the correct instruction from among many instructions. When the user gives instructions to the computer, then all those instructions are saved in the memory. After that, the fetch operation is started.

The instructions that the user gives to the computer are divided into small parts in the computer. After that which instruction will be processed through the first fetch operation is selected. That instruction is passed through the RAM to the CPU and processed.

Decode

When the instruction is received by the CPU, it starts decoding it. The CPU converts all these decoded instructions into signals and sends them to other parts.

Execute

The CPU executes all that instruction after decoding it. After that, the result of that executed instruction is visible through the output device. Also saves the result of the executed instruction to the secondary storage unit.

What is CPU Core?

The meaning of the core in the CPU is considered to be the capacity to do its work. In the earlier CPUs, there was only one core in a processor. Because of this, the CPU was able to do only one task at a time.

Today multi-core processors have started coming. That is, many tasks can be completed simultaneously. The more cores there are, the more efficient the CPU will be. Generally, a laptop or desktop has a CPU with 2 cores. But today’s laptops have a new generation CPU, which has 4 cores.

CPU Core

Some Examples of multi-core Processors:

Dual-core, Core 2 duo, Octa-core, etc.

What is Threading?

Just as the CPU is divided into cores in a computer, the core is also divided into subparts. This is called a thread. The number of threads in any computer is more than twice the number of cores.

For example, if there is a dual-core CPU, then it has 2 cores. There are 4 threads in 2 cores. A quad-core CPU has 4 cores and 8 threads.

A thread starts when we start processing a task. Like when starting an application, the thread starts its own instructions and handles that application. If more applications are started simultaneously, then the thread is also created and handled accordingly.

Thread is an important component of a computer. For this, we are able to do multiple tasks on the computer and quickly. Because of this, today’s computers are called multitasking machines.

Models of CPU

There are many models of CPUs nowadays. Most of the CPUs are being made exclusively by Intel and AMD company. In today’s time, many models of Intel processors and many generations have been made in it.

Intel CPU

Intel company has many CPUs. Like Pentium, Celeron, Dual-core, Core 2 Duo, Core i3, i5, i7, etc. As new CPUs are being made with new technology, the preference for the old model is becoming less and less.

The Celeron processor has more performance than the Pentium processor. Core i3 has more performance than dual-core. i5 is more than i3 and i7 have more performance than i5.

Some of the dual-core technology has been put in the i3 processor, so both these processors work almost identically. However, due to the Turbo Boost Technology 2.0 feature in i5 and i7 CPUs, it works better than others.

Due to this feature, the clock speed of the processor helps to work faster than the normal speed. For example, if an i7 CPU processes at 3 GHz, then it works by increasing it to 3.5 GHz. This technology helps to take the CPU to the maximum speed.

AMD CPU

Why switch to an AMD processor if you’re getting a new computer or upgrading your system? Because in today’s AMD processor market in a very good price and good performance is available.

AMD CPUs are available at a much cheaper cost than Intel’s CPUs. The AMD CPU is best suited for the measurement use of the hardcore gamer, graphic designer, and computer user.

AMD Ryzen 9 5900X is a very good CPU. It has 12 cores and doubles which means 24 threads. In which it is very fast to run any application in it. Its minimum clock speed is 3 GHz and its maximum clock speed is 4.7 GHz.

If someone wants a budget computer in the work price, then he can go towards AMD CPU.

Conclusion

In conclusion, the CPU is like the brain of a computer. It does many important things to make the computer work properly.

First, it fetches instructions from memory. These instructions tell the CPU what to do. Then, it decodes the instructions and performs the tasks they tell it to do. This includes things like calculations and making decisions.

The CPU also controls how data moves between different parts of the computer. It manages the memory, where information is stored, and it handles input and output devices like keyboards and screens.

Overall, the processor is really important because it does all the important work that makes your computer run. It is like the brain that controls everything and makes sure that everything in the computer runs smoothly. Without a Processor, your computer would not be able to start.
