ADSL - Asymmetric Digital Subscriber Line

By , About.com Guide

Definition: ADSL is a type of Digital Subscriber Line (DSL) Internet service commonly used in homes. The 'A' in ADSL refers to its asymmetry: ADSL connections provide comparatively more bandwidth for downloads than for uploads.

ADSL is designed to support the typical home user who frequently downloads large amounts of data from Web sites and P2P networks but upload relatively less often. ADSL works by allocating a majority of the available phone line frequencies for communication of downstream traffic.

In other respects, ADSL possesses all of the characteristics one associates with DSL, including "high-speed" service, an "always on" combination of voice and data support, and availability and performance that is limited by physical distance. ADSL is technically capable of up to 6 Mbps (roughly 6000 Kbps), but ADSL customers in practice obtain 2 Mbps or lower for downloads and up to 512 Kbps for uploads.
