ADSL

ADSL is an abbreviation for Asynchronous Digital Subscriber Line. Sometimes seen as Asymmetric Digital Subscriber Line. ADSL connections are high-speed broadband lines that use an ordinairy telephone line. ADSL lines have a slower upload speed than download speed which is fine for most home users, who will be mostly receiving data from the Internet. An alternative would be an DSL line (Digital Subscriber Line) which has no limitations on upload speeds and so works at the same speed in both directions. ADSL lines need to be close to telephone exchanges, current technology extends to approx. 6 kilometres for an ADSL broadband line.
