The motherboard, also known as the mainboard, systemboard, or motherboard, is one of the most basic and important components of a computer. The main board is a rectangular circuit board, which is installed with the main circuit system of the computer. It has the BIOS chip, I/O control chip, keyboard and panel control switch interface, indicator jack, expansion slot, DC power supply connector of the main board and the card
The motherboard, also known as the mother board, is installed in the main box of the computer. It is one of the most basic and important components of the computer and plays a decisive role in the whole computer system. The quality of the motherboard manufacturing determines the stability of the hardware system. The motherboard is closely related to the CPU. Every major upgrade of the CPU inevitably leads to the replacement of the motherboard. The motherboard is the core of the computer hardware system, and it is also the largest printed circuit board in the main box.
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 must be completed through the motherboard when the computer is running normally. Whether the computer performance can give full play to, whether the hardware function is enough, and how hardware compatibility, etc., all depend on the design of the motherboard. The advantages and disadvantages of the motherboard to some extent determines the overall performance of a computer, service life and function expansion ability.
The main board has an open structure. Most motherboards have 6-15 expansion slots for PC peripheral control cards (adapters) to plug in. By replacing these cards, the corresponding subsystem of the microcomputer can be upgraded locally, so that manufacturers and users have more flexibility in the configuration of models. In short, the main board plays a decisive role in the whole microcomputer system. It can be said that the type and grade of the motherboard determines the type and grade of the whole microcomputer system, and the performance of the motherboard affects the performance of the whole microcomputer system
