Quizplus · Accepted Answer

Asymmetric DSL (ADSL) has a lower transmission rate upstream than downstream, which means that the speed of data transfer is faster when receiving data than when sending data. This is because ADSL was designed to cater to the needs of home users who tend to download more data than they upload. In contrast, Symmetric DSL (SDSL), Very High-Speed DSL (VDSL), and Integrated Services Digital Network DSL (ISDN DSL) have equal transmission rates upstream and downstream.
