主板，也叫母板，安装在计算机主机箱内，是计算机zui基本也是zui重要的部件之一，在整个计算机系统中扮演着举足轻重的角色。主板制造质量的高低，决定了硬件系统的稳定性。主板与CPU关系密切，每一次CPU的重大升级，必然导致主板的换代。主板是计算机硬件系统的核心，也是主机箱内面积zui大的一块印刷电路板。主板的主要功能是传输各种电子信号，部分芯片也负责初步处理一些外围数据。计算机主机中的各个部件都是通过主板来连接的，计算机在正常运行时对系统内存、存储设备和其他I/O设备的操控都必须通过主板来完成。计算机性能是否能够充分发挥，硬件功能是否足够，以及硬件兼容性如何等，都取决于主板的设计。主板的优劣在某种程度上决定了一台计算机的整体性能、使用年限以及功能扩展能力。

主板采用了开放式结构。主板上大都有6-15个扩展插槽，供PC机外围设备的控制卡（适配器）插接。通过更换这些插卡，可以对微机的相应子系统进行局部升级，使厂家和用户在配置机型方面有更大的灵活性。总之，主板在整个微机系统中扮演着举足轻重的角色。可以说，主板的类型和档次决定着整个微机系统的类型和档次，主板的性能影响着整个微机系统的性能

The motherboard, also known as the motherboard, is installed in the main box of the computer, is one of the most basic and important components of the computer, and plays a pivotal role in the entire computer system. The manufacturing quality of the motherboard determines the stability of the hardware system. The motherboard is closely related to the CPU, and every major upgrade of the CPU will inevitably lead to the replacement of the motherboard. The motherboard is the core of the computer hardware system and 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. The various 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 during the normal operation of the computer. Whether the computer performance can be fully played, whether the hardware function is enough, and how the hardware compatibility depends on the design of the motherboard. To some extent, the advantages and disadvantages of the motherboard determine the overall performance, service life and function expansion ability of a computer.

The main board adopts an open structure. Most of the motherboards have 6-15 expansion slots for the PC peripheral control card (adapter) to plug in. By replacing these cards, the corresponding subsystems of the microcomputer can be locally upgraded, so that manufacturers and users have greater flexibility in the configuration of models. In short, the motherboard plays an important role in the entire microcomputer system. It can be said that the type and grade of the motherboard determine the type and grade of the entire microcomputer system, and the performance of the motherboard affects the performance of the entire microcomputer system
