服务器的英文名称为“ Server”，是指在网络上提供各种服务的高性能计算机。作为网络的节点，存储、处理网络上80％的数据、信息，因此也被称为网络的灵魂。
服务器和普通计算机的功能是类似的。只是相对于普通计算机，服务器在稳定性、安全性、性能等方面都要求更高，因此CPU、芯片组、内存、磁盘系统、网络等硬件和普通计算机有所不同。具体来说，服务器与普通计算机的主要区别包括：
1.通信方式为一对多：PC、平板、手机等固定或移动的网络终端，上网、获取资讯、与外界沟通、娱乐等，必然要经过服务器，服务器通过“一对多”来组织和领导这些设备。
2.资源通过网络共享：服务器通过侦听网络上其它终端（Client）提交的服务请求，在网络操作系统的控制下，将与其相连的硬盘、打印机、Modem及各种专用通讯设备提供给网络上的客户站点共享，也能为网络用户提供集中计算、信息发表及数据管理等服务。
3.硬件性能更加强大：服务器的高性能主要体现在高速度的运算能力、长时间的可靠运行、强大的外部数据吞吐能力等方面。
服务器厂商会根据不同的应用场景，对服务器进行差异化设计，目前主要的应用场景包括文件交互、数据存储和查询、应用程序应答与运行等。
