Telnet ------ A program on the Internet that allows logins to another computer to run software there. Telnet allows a user at one site to interact with a remote system at another site as if the user's terminal was connected directly to the remote computer.

With telnet, you can browse menus, read text files, use gopher services, and search online databases. Sometimes, you can join live, interactive games and chat with other callers. Usually, you cannot download files or list file directories.

Telnet is not available to users who have email only access to the Internet.

To telnet a remote computer, you must know its name. This can either be in words, like "vm1.nodak.edu", or a numeric address, like "134.129.111.1". Some services require that you connect to a specific "port" on the remote system. Enter the port number, if there is one, after the Internet address.

WAIS (Wide Area Information Servers) ------------------------------------ A kind of indexed online search tool to locate items based on what they contain - usually keyword text searches. It is a powerful tool for concurrent searches of large databases and/or newsgroups on the Internet.

To access the WHOIS, telnet to rs.internic.net. When greeted by the host, type "WHOIS" and press RETURN. It also has a gopher service (type "gopher" go access, instead of "wais").

WWW (World Wide Web) -------------------- is much like Gopher in that it provides top level access down to other services on the Internet. WWW uses a hypertext interface with cross links between things. You can use highlighted words to jump off onto another track.

WYSIWYG ------- What You See is What You Get.

X.25 ---- A CCITT standard communications protocol used internationally in packet data networks. It provides error-checked communication between packet data networks and their users or other networks.

Rather than sending a stream of bits like a modem, an X.25 router sends packets of data. There are different packet sizes and types. Each packet contains data to be transmitted, information about the packet's origin, destination, size, and its place in the order of the packets sent. There are clear packets that perform the equivalent of hanging-up the phone. There are reset, restart, and diagnostic packets. On the receiving end, the packet assembler/ disassembler (PAD) in the router translates the packets back into a readable format.
