Computer chassis motherboard, also known as the motherboard (mainboard), system board (systemboard) or motherboard (motherboard); it is divided into commercial motherboards and industrial motherboards. It is installed in the chassis, is the most basic microcomputer is also one of the most important components. The motherboard is generally a rectangular circuit board, installed on the composition of the computer's main circuit system, generally BIOS chip, I / O control chip, key and panel control switch interface, indicator plugs, expansion slots, motherboards and plug-in cards, DC power supply connectors and other components.
2, memory stick
Memory stick is the CPU can be addressed through the bus, and read and write operations of the computer components. Memory sticks in the history of personal computers used to be an extension of the main memory. With the computer software and hardware technology constantly updated requirements, memory sticks have become read and write memory as a whole. We usually say the size of the computer memory (RAM), that is, the total capacity of the memory stick.
3, CPU
Central Processing Unit (CPU, Central Processing Unit) is an ultra-large-scale integrated circuits, is a computer computing core (Core) and control core (Control Unit). Its function is mainly to interpret computer instructions and process data in computer software.
4, graphics card
Video card (Video card, Graphics card) full name of the display interface card, also known as the display adapter, is the most basic configuration of the computer, one of the most important accessories. As an important part of the computer mainframe, the graphics card is a digital-to-analog signal conversion device for computers, and bears the task of displaying graphics output. Graphics card connected to the computer motherboard, it will be the computer's digital signals into analog signals for the monitor to display, at the same time, the graphics card is still image processing capabilities, can assist the CPU to work to improve the overall operating speed. For people engaged in professional graphic design graphics card is very important. The main suppliers of graphics chips for civilian and military graphics cards are AMD (Super Micro Semiconductor) and Nvidia (Nvidia). The top500 computers, nowadays, all contain graphics card computing cores. In scientific computing, graphics cards are called display acceleration cards.
5, hard disk
Hard disk is one of the main storage media of the computer, consisting of one or more disks made of aluminum or glass. The disks are covered with a ferromagnetic material.
6, optical drive
Optical drive Pinyin Guāngqū; optical drive, computer used to read and write the contents of the CD-ROM machine, but also in the desktop and laptop portable computers is more common in a component. With the increasingly widespread use of multimedia, making the optical drive in the computer has become a standard configuration of many accessories. Optical drives can be categorized as CD-ROM drives, DVD drives (DVD-ROM), Compaq (COMBO), Blu-ray drives (BD-ROM) and burners.
7, fan
Computer fans, also known as cooling fans, provided to the radiator and chassis use. The general size of the cooling fan on the market size from the diameter of 2.5cm to 30cm are available, the thickness of 6mm to 76mm are available, and according to different operational requirements, can be used in rare AC (alternating current, by the household socket to take power) and the common D power (DC, by the computer fire cow or motherboard to take power), most of the use of two-phase motors (two sets of copper coils, **** four units), in the case of the rotational speed not high Favorable to save production costs.
8, chassis
Chassis as part of the computer accessories, it plays a major role in placing and fixing the computer accessories, play a supporting and protective role. In addition, the computer chassis has an important role in shielding electromagnetic radiation.
9, power supply
Computer power supply is a closed independent components installed in the host box, its role is to AC power through a switching power transformer for 5V, -5V, +12V, -12V, +3.3V, such as stable DC power supply to supply the host box system version of the floppy disk, hard disk drive and a variety of adapters to expand the card and other system components used.
10, monitor
Monitor (display) is usually also known as the monitor. The monitor is a computer belonging to the I / O devices, that is, input and output devices. It is a display tool that displays a certain electronic file through a specific transmission device onto a screen and then reflects it back to the human eye.
11, the mouse
mouse: a computer input device, wired and wireless two kinds, but also the computer display system vertical and horizontal coordinates of the positioning of the indicator, because of the shape of the mouse and the name "mouse" (RTHK as a mouse).
12, keyboard
Keyboard is used to operate the operation of equipment, a command and data input devices, but also refers to the operation of a machine or device through the system arrangements for a set of functional keys (such as typewriters, computer keyboards). Keyboard also forms part of a keyboard instrument and can also refer to a musical instrument that uses a keyboard, such as a piano, a digital piano or an electronic organ, etc. A keyboard helps in practicing typing. If there is anything you do not understand can go to the most will shopping forum and everyone to exchange learning to explore, I wish everyone to assemble their own computer.
