通信英文缩写
AACAccess controller,接入控制器ADC移动ADC，是Application data center的缩写，其实是ASP模式与IDC业务的结合的演以及移动进销存等四款行业应用托管解决方案。
ADSL是我们常说的宽带。
AP以太网卡，那么AP就是传统有线网络中的HUB，也是目前组建小型无线局域网时最常用的设备。
AP相当于一个连接有线网和无线网的桥梁，其主要作用是了完善的无线网络管理功能。
AP的室内覆盖范围一般是30m～100m，目前不少厂商的AP产品可以互联，以增加WLAN覆盖面积。
也正因为每个AP的覆盖范围都有一定的限制，正如手机可以在基站之间漫游一样，无线局域网客户端也可以在AP之间漫游。
AP的功能：中继、桥接、“主从模式”。
无线AP与无线路由的区别：无线AP，也就是无线接入点，简单来说就是无线网络中的无线交换机，它是移动终端用户进入有线网络的接入点，覆盖距离为几十米至上百米，目前主要之间可以进行无线链接，从而可以扩大无线网络的覆盖范围。
目前的无线AP可分为两类：单纯型AP和扩展型AP。
单纯型AP由于缺少了路由功能，相当于无线交换机，仅提供一个无线信号发射的功能。
工作原理是将网络信号通过双绞线传送过来，经过无线AP的编译，将电信号转换成为无线电讯号发送出来，形成无线网络的覆盖。
根据不同的功率，网络覆盖程度也是不同的，一般无线AP的最大覆盖距离可达400米。
扩展型AP就是无线路由器了。
无线路由器就是带有无线覆盖功能的路由器，主要应用于用户上网和无线覆盖。
通过路由功能，可以实现家庭无线网络中的Internet连接共享，也能实现ADSL和小区宽带的无线共享接入。
通过无线路由器把无线和有线连接的终端都分配到一个子网，使得子网内的各种设备可以方便的交换数据。
AS（Autonomous System）自治系统自治系统：autonomous system。
在互联网中，一个自治系统(AS)是一个有权自主地决定在本系统中应采用何种路由协议的小型单位。
