主板是计算机硬件的核心部件，也被称为主板、母板或系统板。它是一块电子线路板，连接了计算机的各个组件，如中央处理器（CPU）、内存、扩展卡、硬盘驱动器、光驱、显示器等。 主板承担着控制和协调计算机内部各个组件的功能。它提供了各种接口和插槽，使得不同的硬件可以相互连接和通信。主板上的芯片组则负责控制数据传输和处理器的运作，同时也提供了电源管理和BIOS（基本输入输出系统）等功能。 主板的选择对电脑的性能和扩展能力有很大影响。不同的主板具有不同的芯片组、插槽类型和接口数量，因此需要根据自己的需求选择适合的主板。一些主板还提供了额外的功能，如内置音频、网络和USB接口等。 总而言之，主板是计算机的核心部件，负责连接和协调计算机的各个硬件组件，是计算机系统正常运行的关键。
