I noticed that DSL is used in residents' homes in the US, but ADSL is used in Europe (I've used it in Italy and Kazakhstan) in residents' homes.

What is the difference between ADSL and DSL?
ADSL is a type of DSL where the upstream and downstream speeds differ (hence the "asymmetric" part). There are many variations of DSL technology for different types of application (HDSL, SDSL, etc).

DSL is either symmetric or asymmetric. Asymmetric provides faster downstream speeds suited for internet usage and video on demand. Symmetric provides the same rate speed coming and going.
ADSL standardized by ANSI as T1.413 and uses existing UTP copper wires to communicate digitally at high speed between the telephone company central office (CO) and the subscriber. ADSL sends information asymmetrically, meaning it is faster one way then the other. ADSL is available in a variety of configurations and speeds.

DSL is via coax eg the same cable used for tv aerials
and ADSL is via the telephone line.
