A digital subscriber line, or DSL, is a communications technology that allows data to travel at very high speeds over standard telephone wire without interrupting normal telephone service.
The primary market for DSL is the home office since the technology makes it easy for residential homes to receive high-speed internet access at a reasonable price. DSL speeds, on the average, run at about 600kbps for downstream and 128kbps for upstream.
The conversation between browsers and servers takes place according to the hypertext transfer protocol, or HTTP.
Written by Tim Berners-Lee, it was first implemented on the web in 1991 as HTTP 0.9. Currently, web browsers and servers support version 1.1 of HTTP. It supports persistent connections, meaning that once a browser connects to a web server, it can receive multiple files through the same connection.
Microsoft’s internet information server, or IIS, is one of the most widely used commercial web server applications on the market. It runs on the Windows operating system and it incorporates all of the tools required by high-traffic commercial websites, such as security, extensions, logging, database interfaces and all of the necessary protocols.
Short for internet service provider, an ISP owns and operates all of the equipment (telephony, digital cable, servers, etc.) that allow you to connect to the internet from your home or office.
Most ISPs sell access to their services for a small monthly fee, which you can access by connecting to your ISP’s computer network through a phone or cable line.
Mbone is short for multicast backbone on the internet, and is an extension to the internet designed to support IP multicasting, or the transmission of data packets to multiple addresses. Most of this traffic is streaming audio and video which, like radio and TV broadcasts, is sent to many people at once. The Mbone was established in 1994 by the Internet Engineering Task Force.
Mbone is likely to go obsolete with the adoption of IPv6 which supports multicasting by default.
