Structure of Computer Motherboard The computer motherboard is the core part of the computer, connecting almost all electronic components. Its structure usually includes the following parts: 1. Baseboard: The main part of the motherboard is composed of an insulating baseboard, which is printed with wiring diagrams of various circuits and capacitors and other components.

2. Processor socket: Used to install the central processor (CPU), which is designed with specific size and specifications according to certain standards.

3. Memory slot: Used to insert computer memory sticks (RAM) to store data and programs in operation. 4. Chipset: Responsible for processing and controlling the interaction of signals and data between various parts. The chipset is composed of a southbridge chip and a northbridge chip, which coordinate the data transmission of the host together. 5. Expansion slots: Such as PCI, PCI-E, etc., providing interfaces for various expansion cards (such as graphics cards, sound cards, etc.). 6. Power interface: Responsible for providing power to the computer motherboard and other components. 2. Working Principles of Computer Motherboard The main function of the motherboard is to provide a connection bridge between various hardware components, ensuring smooth communication and data transmission between them. The specific working principles are as follows: 1. Initialization: When starting up, the motherboard will perform self-detection and initialization operations to allocate resources for the CPU and other hardware devices. 2. Data transmission: The motherboard is responsible for transmitting the processing results of the CPU and other data to other devices through the chipset and various interfaces, while receiving data from other devices. 3. Control signals: The chipset and circuits on the motherboard are responsible for generating and transmitting control signals to ensure that each hardware component can work in a predetermined order and manner. 4. Power management: The power management unit on the motherboard manages the power supply of the computer to ensure that the power needs of the computer in various working states are met.
