A good computer, the quality of computer hardware is very important, and for those who want to assemble a computer, they must know the type of hardware, then what does computer hardware mean? What are the computer hardware? The following decoration home decoration network Xiaobian will give you detailed answers, I hope to help everyone.
What does computer hardware mean?
Computer hardware, including all physical parts of a computer, to distinguish between the data it contains or executes and the software that provides instructions to the hardware to complete the task; mainly includes the 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.
What are the computer hardware?
1. Motherboard: The motherboard carries the CPU, memory and slots provided for the expansion card (but the CPU and memory are not integrated on the motherboard, not the accessories of the motherboard, and also belong to the computer hardware). The motherboard is also called the motherboard and system. Board or motherboard; it is mounted inside the chassis and is one of the most basic and important components of a microcomputer.
2, power: editing power is the source of power for the computer, it has motherboard interface 20 + 4pin, CPU interface (4 + 4pin) 1, graphics card interface (6 + 2Pin) 2, hard disk interface (SATA) 4 Three power supply interfaces (large 4pin) are used to supply power to the corresponding hardware in the computer.
3, memory: Memory is one of the important components of the computer, it is a bridge to communicate with the CPU. All programs in the computer run in memory, so the performance of the memory has a huge impact on the computer. The memory is also referred to as an internal memory, and is used to temporarily store arithmetic data in the CPU and data exchanged with an external memory such as a hard disk. As long as the computer is running, the CPU will transfer the data that needs to be calculated to the memory for calculation. When the operation is completed, the CPU will transmit the result. The operation of the memory also determines the stable operation of the computer. The memory is composed of a memory chip, a circuit board, a gold finger, and the like.
4, hard disk: Hard disk is one of the main storage media of the computer, consisting of one or more discs made of aluminum or glass. These discs are covered with a ferromagnetic material. Most hard drives are fixed hard drives that are permanently sealed to the hard drive. Hard disks are classified into solid state drives (SSDs) and mechanical hard disks (HDDs); SSDs use flash granules for storage, and HDDs use magnetic disks for storage.
5, graphics card: graphics card full name display interface card, also known as display adapter, display configuration card referred to as graphics card, is one of the most basic components of personal computers. The purpose of the graphics card is to convert and display the display information required by the computer system, and provide a line scan signal to the display to control the correct display of the display. It is an important component for connecting the display and the motherboard of the personal computer, and is an important device for "human-machine dialogue". one.
6. Bus: The bus is a high-speed functional component that constitutes a computer system, such as a bus connected to a memory or a channel.
The bus in a single processor system is roughly divided into three categories: (1) internal bus, the CPU internally connects the registers and the bus between the computing components; (2) the system bus, the CPU with the calculation; the I/O bus, The interconnection mechanism of the low-speed I/O computer system is a common path for data transmission between multiple system functional components.
7, input devices: keyboard, mouse, trackpad, trackball, digital input board and input pen / pointer, touch screen, game controller, game joystick, microphone, scanner, barcode reader, network Cameras, digital cameras, mobile phones, and a large number of USB external products.
8, output devices: printers, dot matrix printers, inkjet printers, laser printers, speakers, displays.
9, computer monitors: including CRT, LCD, LED, PDP.
10, built-in memory: hard disk, disk array controller.
11, portable storage devices: 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 drive, flash memory, thumb drive, memory card, SD, CF, MMC SM, SSD (mobile hard drive).
