Xiaobian to share with you what the computer hosts include, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's learn about it!

The host includes: 1, the motherboard, installed in the chassis, is one of the most basic and important components of the microcomputer; 2, central processing unit; 3, memory; 4, hard disk; 5, graphics card.

Hosts include:

First, the motherboard

Computer chassis motherboard, also known as motherboard (mainboard), system board (systemboard) or motherboard (motherboard); it is divided into commercial motherboard and industrial motherboard. It is installed in the chassis and is one of the most basic and important components of the microcomputer. The motherboard is generally a rectangular circuit board, which is equipped with the main circuit system of the computer, such as BIOS chip, Imax O control chip, keyboard and panel control switch interface, indicator connector, expansion slot, motherboard and DC power connector of the card and so on.

II. Central processing unit

Central processing unit (CPU,Central Processing Unit) is a very large-scale integrated circuit, which is the computing core (Core) and control core (Control Unit) of a computer. Its main function is to interpret computer instructions and process data in computer software.

The CPU mainly includes arithmetic unit (arithmetic logic operation unit, ALU,Arithmetic Logic Unit), controller and cache memory (Cache) and the data (Data), control and state bus (Bus) that realize the connection between them. It is called the three core components of electronic computer together with internal memory (Memory) and input / output (I / O) devices.

III. Memory

One of the important parts of the computer, it is the bridge to communicate with CPU. All programs in the computer run in memory, so the performance of memory has a great impact on the computer. Memory (Memory), also known as internal memory and main memory, is used to temporarily store operational data in CPU and data exchanged with external memory such as hard disk.

As long as the computer is running, CPU will transfer the data needed for operation to memory for operation, and when the operation is completed, CPU will transmit the results. The operation of memory also determines the stable operation of the computer. The memory is composed of memory chip, circuit board, gold finger and so on.

Fourth, hard disk

As a storage device, it has been playing an indispensable role since the birth of the computer. To some extent, the performance of the computer only affects the speed of computing data, while the task of storage devices is to ensure the survival of all kinds of operational data.

5. Graphics card

It is one of the most basic components of the personal computer. its purpose is to convert the display information needed by the computer system to drive the display, to provide progressive or interlaced scanning signals to the display, and to control the correct display of the display. it is an important component connecting the display and the personal computer motherboard, and it is one of the important devices of "man-machine dialogue".

The above is all the contents of the article "what are the hosts in the computer?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
