Telnet is a way of accessing computers that you would normally dial up with your modem, such as BBS's. When your browser encounters an address starting with telnet:, it will call up the Telnet program and tell it the location of the Telnet computer. You can then access the computer you Telnet-ed, just as you would if you had dialed into it with a modem. Today, Telnet is not very common, since the Internet has replaced the need for Telnet. The only reason it still exists today is to allow people to access BBS's that are still in operation. To find Telnet sites, your best bet is probably with a search engine. Try AltaVista or Yahoo!
