Briefly describe the main components on the motherboard.

1. Baseband part Baseband chip and power management chip: responsible for coding. Radio frequency part RF processor and RF amplifier: realize the function of sending and receiving signals Other parts CPU, memory, various controllers (including touch screen, Bluetooth, WIFI, sensor, etc.).

2. Chipset. The two largest chips on the motherboard are the chipsets of the motherboard.It is divided into the north bridge (MCH: memory controller) and the south bridge (ICH: I/O control center). The key to the scientific and technological accountant and technical performance of a motherboard lies in the adoption of the Hechuo chipset, which can be said to be the soul of the motherboard. CPU slot/socket.

3. Generally, there are BIOS chip, I/O control chip, keyboard and panel control switch interface, indicator light plug-in, expansion slot, motherboard and plug-in DC power supply plug-in and other components. The most important component on the motherboard is the chipset.

求 the structure diagram of the computer motherboard, which should be detailed and clear

Among them, the AT board type is the most basic board type, which is characterized by simple structure and low price. Its standard size is 32cmX30.48cm. The AT motherboard needs to be used with the AT chassis power supply, etc., and has now been eliminated.

2. In addition, if the circuit board is to be used as a motherboard on the computer, you need to make a different board type. Among them, the AT plate type is the most basic plate type, which is characterized by simple structure and low price. Its standard size is 32cmX30.48cm, the AT motherboard needs to be used with the AT chassis power supply, etc., and has now been eliminated.

3. The internal structure diagram and name of the desktop computer host are as follows: host box: the desktop computer host usually adopts ATX structure chassis. Motherboard: The motherboard is one of the most important components in the computer host. It is covered with various electronic components, such as CPU, memory, hard disk controller, power controller, serial port, parallel port, etc.
