DSL (Digital Subscriber Line)

DSL is an acronym that stands for Digital Subscriber Line. It refers to a transmission standard under which data can be transmitted and received at high transmission rates via a bifilar copper line of the telephone network. Because DSL data is transmitted in a different frequency range than telephone data (voice or fax), users can speak on the telephone and surf the Internet at the same time. A DSL connection offers much faster Internet speeds than earlier modem and ISDN connections.
