Most ISPs have a network of servers (mail, news, Web, and the like), routers, and modems attached to a permanent, high speed Internet "backbone" connection. Subscribers can then dial into the local network to gain Internet access without having to maintain servers, file for domain names, or learn Unix.

High Speed dialup
is a new generation of dialup access, which utilizes compression and caching technologies to speed up Web surfing and bring back the joy of using the Internet through a dial connection. A high speed dialup

Digital Subscriber Line (DSL) is a new digital technology that brings high bandwidth to homes and small to medium sized businesses over the ordinary copper telephone lines presently installed behind your walls. DSL technology is available in various flavors, collectively referred to as xDSL. It allows voice, video and data to be transmitted at very fast speeds, 20 or more times faster than an ordinary 56K modem and 10 times faster than ISDN.
As the name implies, satellite Internet uses a space satellite to deliver broadband access to homes. Because of this, even homes in areas where DSL or Cable are not available can receive high speed access. Of course that access does come at a price. Satellite Internet
is one of the more costly broadband alternatives.
