1. Circuit Board The circuit board is the foundation of the motherboard, consisting of insulating materials and conductive materials. On the circuit board, various components are connected through wiring and welding to form a complete circuit system. 2. Chipset The chipset is the core of the motherboard, composed of multiple chips, including the northbridge chip and southbridge chip. The northbridge chip is mainly responsible for data transmission between high-speed devices such as the CPU, memory, and graphics card, while the southbridge chip is responsible for data transmission and control of low-speed devices such as USB ports, audio interfaces, etc. 3. Memory Slot Memory slots are interfaces for connecting memory sticks. There are usually multiple memory slots on the motherboard, which can be added or reduced according to needs. 4. Expansion Slots Expansion slots are interfaces for connecting various expansion cards, such as graphics cards, sound cards, network cards, etc. These expansion cards can enhance the functionality of the computer, such as improving graphic processing power, enhancing audio effects, etc. 5. Interfaces The motherboard also has various interfaces such as power interfaces, USB ports, SATA interfaces, etc. These interfaces are used to connect various external devices and power supplies to ensure stable computer operation. II. Detailed Structure of the Motherboard Besides the above basic structure, there are many other detailed parts of the motherboard, such as BIOS chips, capacitors, resistors, etc. 1. BIOS Chip The BIOS chip is a chip that stores the basic input/output system program. It is responsible for the computer's boot process and the initialization of hardware devices. The BIOS chip is usually located near the northbridge chip of the motherboard. 2. Capacitors and Resistors Capacitors and resistors are important components on the circuit board. They play a role in filtering, voltage stabilization, current regulation in the circuit to ensure stable computer operation. 3. Summary In summary, the structure of
