Motherboard, also called motherboard, is installed in the main computer chassis, which is one of the most basic and important parts of the computer and plays an important role in the whole computer system. The quality of motherboard manufacturing determines the stability of hardware system. Motherboard is closely related to CPU, and every major upgrade of CPU will inevitably lead to the replacement of motherboard. Motherboard is the core of computer hardware system and the largest printed circuit board in the main chassis. The main function of the motherboard is to transmit various electronic signals, and some chips are also responsible for preliminary processing of some peripheral data. All the components in the computer host are connected through the motherboard, and the control of the system memory, storage devices and other I/O devices during normal operation of the computer must be completed through the motherboard. Whether the computer performance can be brought into full play, whether the hardware functions are sufficient, and how compatible the hardware is, etc., all depend on the design of the motherboard. The quality of the motherboard determines the overall performance, service life and function expansion ability of a computer to some extent.
