ADSL vs. DSL

[jnjcasper]

What is the difference between ADSL and DSL? In the US all I ever heard about was DSL, but here in Tunisia its not available, but ADSL is. Anyone know?

ADSL (Asymmetric Digital Subscriber Line, or DSL for short) is a high-speed Internet access service that utilizes existing copper telephones lines to send and receive data at speeds that far exceed conventional dial-up modems.

its the same thing, just that "DSL" encompasses more types of product.

You can find a decent explanation on our wiki pages; DSL and ADSL.
