What is ADSL?
Asymmetric Digital Subscriber Line (ADSL) is currently the most popular flavor of DSL. It is widely deployed and used by many home consumers and SMBs. ADSL is called "asymmetric" because most of its two-way bandwidth is devoted to the downstream direction that sends data to the user. Only a small portion of bandwidth is available for upstreaming. Most Internet users, and especially those who use graphics- or multi-media intensive Web data, need lots of downstream bandwidth. For these applications, user requests and responses are small and require little upstream bandwidth. Using ADSL, up to 8 Mbps of data can be sent downstream and up to 640 Kbps are available for upstreaming. The high downstream bandwidth means that your telephone line will be able to bring large data files, video, audio, and 3-D images to your computer or hooked-in TV set. And, since it supports Plain Old Telephone Service (POTS), a small portion of the downstream bandwidth can be devoted to voice, rather than data, so you can make phone calls without having to use another separate line.
