Adapter适配器 一种实现计算机和外部设备之间交换信息的中间装置。它可以是一块含CPU的印刷电路板,也可以集成在主机板上。若该适配器使计算机具有网络通信功能,则它就是网络接口适配器,也称网卡。 ADSL(Asymmetric Digital Subscriber Line)非对称数字用户线路 是一种调制解调技术,用于在铜制双绞线上同时传输语音和数据,它可提供达9Mb/s的数据下行速率、800Kbps的数据上行速率,以及4KHz
Adapter An intermediate device that enables the exchange of information between a computer and an external device. It can be a CPU-containing printed circuit board, can also be integrated in the motherboard. If the adapter to make the computer network communication capabilities, it is the network interface adapter, also known as network card. Asymmetric Digital Subscriber Line (ADSL) Asymmetric Digital Subscriber Line is a modem technology used to transmit voice and data simultaneously over copper twisted pair. It provides up to 9Mb / s data rate and 800Kbps data Uplink rate, and 4KHz
