DSL or xDSL, is a family of technologies that provide digital data transmission over the wires of a local telephone network. DSL originally stood for digital subscriber loop, although in recent years, the term digital subscriber line has been widely adopted as a more marketing-friendly term for ADSL, which is the most popular version of consumer-ready DSL. DSL uses high frequency, while regular telephone uses low frequency on the same telephone line.

Typically, the download speed of consumer DSL services ranges from 256 kilobits per second (kbit/s) to 24,000 kbit/s, depending on DSL technology, line conditions and service level implemented. Typically, upload speed is lower than download speed for Asymmetric Digital Subscriber Line (ADSL) and equal to download speed for the rarer Symmetric Digital Subscriber Line (SDSL).

      Asymmetric Digital Subscriber Line (ADSL)

      Asymmetric digital subscriber line (ADSL) is a new modem technology that converts existing twisted-pair telephone lines into access paths for high-speed communications of various sorts. Overview ADSL can transmit more than 6 Mbps to a subscriber - enough to provide Internet access, video-on-demand, and LAN access.

      Digital Subscriber Line (DSL) and the Evolution of Asynchronous Transfer Mode (ATM)

      Overview Deregulation, together with increasing consumer and business demand for high bandwidth services, has led to increased competition among service providers. This increase in competition has, in turn, presented providers with an important set of business challenges. With increased competition, it becomes critical for providers to market and press for innovative services. Providers must move up the value chain in service delivery,...

Mark Twain quote for the day:

We have to be despised by somebody whom we regard as above us or we are not happy; we have to have somebody to worship and envy or we cannot be content. In America we manifest this in all the ancient and customary ways. In public we scoff at titles and hereditary privilege but privately we hanker after them, and when we get a chance we buy them for cash and a daughter.
- Mark Twain in Eruption
