Digital Subscriber Line or Loop
A family of technologies that provide digital data transmission over the wires of a local telephone network.
DSL originally stood for digital subscriber loop, although in recent years, many have adopted digital subscriber line as a more marketing-friendly term for the most popular version of DSL, ADSL.
Typically, the download speed of consumer DSL services ranges from 256 kilobits per second (kbit/s) to 24,000kbit/s, depending on DSL technology, line conditions and service level implemented.
Typically, upload speed is lower than download speed for Asymmetric Digital Subscriber
