ADSL
Asymmetric Digital Subscriber Line (ADSL) is the most popular form
of xDSL technology. The key to ADSL is that the upstream and
downstream bandwidth is asymmetric, or uneven. In practice, the
bandwidth from the provider to the user (downstream) will be the
higher speed path. This is in part due to the limitation of the
telephone cabling system and the desire to accommodate the typical
Internet usage pattern where the majority of data is being sent to
the user (programs, graphics, sounds and video) with minimal upload
capacity required (keystrokes and mouse clicks). Downstream speeds
typically range from 768 Kb/s to 9 Mb/s Upstream speeds typically
range from 64Kb/s to 1.5Mb/s.
