The Computer
Dictionary
DSL
Digital Subscriber Line
DSL and its sub-categories- xDSL, refer
collectively to a high-speed transmission method of connecting
a computer or computer network to the Internet. The xDSL's are
simular to ISDN in that both use existing copper telephone
lines, and both can only be utilized if the computer location
is no more than 20,000 feet from the nearest telephone
switching station. XDSL's are, however, faster than ISDN as
well as cable connections. Because of this twerky distance
restriction, xDSL's are only available in some areas. For this
reason, they are sometimes refered to as "last-mile
technology."
There is a long alphabetical list of various forms of DSL.
In The Computer Dictionary, we cover many of them in
four main categories: ADSL, HDSL, SDSL, and G.SHDSL.
