ADSL

Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL supports data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate). Providers usually market ADSL as a service for consumers to connect to the Internet in a relatively passive mode: able to use the higher speed direction for the download" from the Internet but not needing to run servers that would require high speed in the other direction.

ADSL is growing in popularity as more areas around the world gain access.

ADSL modems are used to connect a single computer or router to a DSL phone line, in order to use an ADSL service.
