In this issue, the editor will bring you about the computer hardware. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Computer hardware includes: chassis, motherboard, cup, memory, bus, power supply, hard disk, storage controller, interface card (sound card, graphics card, modem interface card, network interface card, TV card, video capture card, etc.), input device (keyboard, mouse, etc.), output device (speaker, monitor, etc.), CPU fan, buzzer and so on.

Computer hardware, including all physical parts of the computer, in order to distinguish the data it includes or executes and the software that provides instructions for the hardware to complete the task; mainly includes: chassis, motherboard, bus, power supply, hard disk, storage controller, interface card, portable storage device, built-in memory, input device, output device, CPU fan, buzzer, etc.

1. Motherboard

The motherboard carries CPU (central processing unit), memory (random access memory) and slots for expansion cards (but CPU and memory are not integrated on the motherboard, are not accessories to the motherboard, and also belong to computer hardware)

The motherboard, also known as the motherboard (mainboard), system board (systemboard) or motherboard (motherboard), is installed in the chassis and is one of the most basic and important components of the microcomputer.

The motherboard is generally a 4-6-layer rectangular circuit board, which is equipped with the main circuit system of the computer, such as BIOS chip, I / O control chip, keyboard and panel control switch interface, indicator connector, expansion slot, motherboard and DC power supply connector of the card.

2. Power supply

The power supply is the source of power for the computer. It has: motherboard interface: 20+4pin, CPU interface (4+4pin): 1, video card interface (6+2Pin): 2, hard disk interface (SATA): 4, power supply interface (big 4pin): 3, respectively, supplying power to the corresponding hardware in the computer

3. Memory

Memory is one of the most important components in the computer, and 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, 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.

4. Hard disk

Hard Disk Drive (English name: HDD full name Winchester hard disk) is one of the main storage media of a computer, which consists of one or more aluminum or glass discs. These discs are covered with ferromagnetic material. The vast majority of hard drives are fixed and permanently sealed in the hard drive.

5. Video card

Display card full name display interface card (Video card,Graphics card), also known as display adapter (Video adapter), display configuration card referred to as graphics card, is one of the most basic components of personal computer.

The purpose of the graphics card is to convert and drive the display information needed by the computer system, provide the line scan signal to the display, and control the correct display of the display. it is an important component connecting the display and the personal computer motherboard. it is one of the important devices of "man-machine dialogue".

Graphics card, as an important part of the host computer, undertakes the task of outputting display graphics, which is very important for people engaged in professional graphic design.

6. Bus

Bus is other high-speed functional components of computer system, such as memory, channel and so on.

Buses in a single-processor system are roughly divided into three categories:

(1) Internal bus: CPU connects the bus between registers and computing units internally.

(2) system bus: CPU same calculation

(3) Ihammer O bus: the interconnection mechanism of medium and low speed Ihammer O computer systems, which is a common path for data transmission between multiple system functional components.

A bus that connects devices to each other.

7. Interface card

Sound card, video card, modem interface card, network interface card, TV card, video capture card, etc.

8. Input device

Keyboard, mouse, touchpad, trackball, digital tablet and pen / pointer, touch screen, game controller, game joystick, microphone, scanner, bar code reader, webcam, digital camera, mobile phone, and a large number of USB external products.

9. Output equipment

Printers, dot matrix printers, inkjet printers, laser printers, speakers, monitors

10. Computer monitor

Including CRT, LCD, LED, PDP

Built-in memory

Hard disk, disk array controller

12. Portable storage device

CD, CD-ROM, CD-RW, CD-R, DVD, DVD/CD-RW, Combo, DVD-ROM, DVD-RW, DVD-R, DVD-RAMDVD+RW, DVD+R, floppy disk, tape drive, external hard disk, flash memory, thumb disk, memory card, SD, CF, MMC SM, SSD (removable hard disk)
