2. Power Supply: The power circuit on the motherboard provides a stable power supply for various components to ensure the normal operation of the computer. 3. Control: The BIOS (Basic Input/Output System) on the motherboard is responsible for controlling the computer's boot process, detecting hardware devices, and loading the operating system. In addition, the chipset on the motherboard is responsible for managing memory, interrupts, DMA (Direct Memory Access), and other operations. 4. Expansion: By installing expansion cards, the motherboard can provide additional functions, such as sound cards, network cards, video cards, etc. III. Importance of the Computer Motherboard 1. Stability and Performance: The quality of the motherboard directly affects the stability and performance of the computer. A good motherboard can provide stable power supply, excellent cooling performance, and excellent connectivity to ensure stable operation and high-performance output of the computer. 2. Hardware Compatibility: The types of interfaces and slots on the motherboard determine the types and number of hardware devices that can be installed. A motherboard with good compatibility can support a variety of hardware devices, making it convenient for users to upgrade and expand. 3. Overall Cost Impact: Although the price of the motherboard accounts for a relatively small proportion in computer hardware, its quality and performance have an important impact on the overall cost and performance of the computer. A high-quality motherboard may have a higher price but can ensure the stability and performance of the computer and reduce maintenance and replacement costs. IV. Conclusion: The computer motherboard, as a core component of computer hardware, has functions such as connection, power supply, control, and expansion. Its quality and performance directly affect the stability and performance of the computer, determine hardware compatibility, and affect overall costs. Therefore, selecting an appropriate motherboard is crucial for building a stable and versatile computer.
