DSL is a type of broadband technology that allows for digital data to be sent at high speeds along already-existing copper telephone lines, while allowing for the transmission of analog (voice) data at the same time. Some of the most common variations on DSL include ADSL, HDSL, SDSL, and VDSL, all of which are considerably faster than an ordinary dialup internet connection.
