The role and name of each component of the computer

A computer is generally composed of CPU, motherboard, memory, hard disk, graphics card, sound card, network card, power supply, chassis, optical drive, speaker, mouse, keyboard, monitor, etc., so what is their role, now talk to friends:

The role of CPU: CPU is the abbreviation of ** processing unit (CNTRAL Pocessing UIT), which can be abbreviated as microprocessor (MCroprocessor), but it is often directly referred to as processor (processor). Don't ignore the role of these abbreviations, the CPU is the heart of the computer, and its importance is as important as the heart is to people.

In fact, the role of the processor is more similar to that of the brain, because it is responsible for processing and computing all the data inside the computer, while the motherboard chipset is more like the heart, which controls the exchange of data. The type of CPU determines the operating system and the corresponding software you use. The CPU is mainly composed of combinators, controllers, register banks and internal buses, etc., which is the core of the PC, and is equipped with memory, input and output interfaces and system buses to form a complete PC.

The role of the motherboard: you can understand it this way, the motherboard is like a platform, or like a highway, the CPU, graphics card, memory, hard disk, etc. are like a car system, no matter how high-end the car is, there must be a suitable highway, if you buy a Ferrari, but travel on a mountain road, it will not be able to play the performance of the car; Of course, the road is good, the car is not good, and the speed is not fast.

The role of hard disk and memory: Memory is the main component in a computer, and it is relative to external memory. The programs we usually use, such as Windows system, typing software, game software, etc., are generally installed on external memory such as hard disks, but only this cannot use its functions.

They must be put into memory to run. In order to really use its function, we usually enter a piece of text or play a game in memory, usually we store a large amount of data to be permanently stored in external memory, and put some temporary or a small amount of data and programs in memory. Hard disk memory is memory, which is divided into random access memory (RAM), read-only memory (ROM), and cache.

Simply because RAM is the most important memory of them all.

RAM is a bit like a blackboard in a classroom, where the teacher keeps writing on the blackboard during class and erases it all after class. RAM requires constant power supply at all times, otherwise data will be lost.

In fact, don't ** and luxury, you open the back cover of your computer, see, look at the computer hardware on the web page, you will know what is what, in fact, it is quite simple!

Just like you, the CPU is your heart, the graphics card is your eyes, and the hardware is your body.

Monitor: You should know what this does, right? Mouse.

Keyboard. Host. Others such as headsets, cameras, etc.

It doesn't matter if there is one.

Did you know that a computer is made up of several parts?

CPU: There are two brands of CPU: Intel and AMD.

Motherboards: There are many brands of motherboards, but most of them are also divided into Intel and AMD platforms. The CPU interface type of the motherboard determines what CPU the motherboard supports.

Memory: There are three types of memory: DDR1, DDR2, and DDR3, and the three types of memory do not need to be mixed. Now they are all using DDR3 memory.

Hard drives: There are two common brands: Western Digital and WestJet.

Graphics card: The graphics card is divided into two interfaces: AGP and PCIe, and the graphics card with the AGP interface has been eliminated, and now the graphics card with the PCIe graphics card interface is used.

Power supply: Choose a power supply that is suitable for the rated and sufficient interface according to the purpose of the computer.

Chassis Display:

Keyboard and mouse speaker.

Desktop computer: It consists of a host computer and a display screen, where the host is the internal organs of the computer and the display screen is the face!

The internal organs of a computer mainly include:

1: Hard Disk 2: Graphics Card and so on. Wait a minute.

Functionally, it is mainly composed of five parts: input device, memory-component, controller, and output device, and structurally, it is divided into three parts: host, input device, and output device!

The main components of a complete computer are as follows:

1. CPU: The Chinese name is ** processor (central processing unit), which is a super-large-scale integrated circuit, which is the computing core and control core of a computer. And its function is to interpret computer instructions and process data in computer software.

At present, the more well-known CPU brands include Intel and AMD.

2. Motherboard: also known as motherboard (English: motherboard, mainboard), is the center or main circuit board that constitutes a complex electronic system such as an electronic computer.

Motherboards can provide a series of interface points for processors, graphics cards, sound cards, hard drives, storage, external devices, and more. At present, the more famous motherboard brands are ASUS and Gigabyte.

3. Memory: In layman's terms, the role of memory in the computer is equivalent to a bridge, which is responsible for the data exchange and processing between the processor on the hardware such as hard disks, motherboards, graphics cards, etc. That's why memory modules are an essential part of a computer.

The larger the memory, the faster the computer will be, under the same computer configuration. At present, the more well-known memory module brands include Kingston and ADATA.

4. Hard disk: Hard disk is one of the main storage media of the computer, which is composed of one or more aluminum or glass discs. Of course, hard disks include solid-state drives (SSD disks, modern hard disks), mechanical hard disks (HDD traditional hard disks), and hybrid hard disks (HHD, a new hard disk born based on traditional mechanical hard disks).

At present, the more well-known hard disk brands are Seagate and Western Digital.

5. Graphics card: Graphics card, also known as display adapter, graphics card, as an important part of the computer host, is a device for digital and analog signal conversion of the computer, and undertakes the task of outputting display graphics. Simply put, it is to control the output of computer images.

Graphics cards are divided into two categories: independent graphics cards (with the advantages of separate video memory, not occupying system memory, etc.) and integrated graphics cards (with the advantages of low quality, good compatibility and low upgrade costs). At present, the more famous graphics card brands include Rainbow, Sapphire, Yinglax, Asus, etc.

6. Monitor: also known as monitor. A monitor is an input and output device that belongs to a computer. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye.

7. Keyboard: The keyboard is a kind of instruction and data input device used to operate the equipment.

8. Mouse: The English name is "mouse", which is an input device of the computer.

A computer consists of five logical components: combinator, controller, memory, input device, and output device.

1. Combinator: Combinator is a component for arithmetic and logical operations.

2. Controller: The controller is a component that realizes the contact between various parts of the computer and the automatic execution of the program, and its function is to take out the commands from the memory in turn, generate control signals, issue instructions to other components, and command the entire operation process. The controller is the center of unified command and coordination of other components.

3. Memory: Memory is a component that stores information, which is divided into memory and external memory. The memory is under the command of the controller and exchanges information with combinators and input and output devices.

External memory is set up to compensate for the lack of memory, and under the control of the controller, it exchanges data with the memory in batches.

4. Input device: The input device is a component that converts data and programs into electrical signals and sends electrical signals into memory. Such as: keyboard, mouse, scanner, microphone, joystick, etc.

5. Output device: The output device is a component that sends the results of computer processing to the host computer. Such as: monitors, printers, speakers, etc.
