Internet Relay Chat (IRC) is
|“||a system which enables computer users connected to the Internet to participate in live typed discussions much like instant messaging or chat lines.||”|
|“||[a] system for chatting that involves special client and server software and informal conventions for participation. . . . IRC requires one site to act as the repository (or "chat site") for the messages.||”|
"IRC is analogous to a telephone party line, using a computer and keyboard rather than a telephone. With IRC, however, at any one time there are thousands of different party lines available, in which collectively tens of thousands of users are engaging in conversations on a huge range of subjects. Moreover, one can create a new party line to discuss a different topic at any time. Some IRC conversations are 'moderated' or include 'channel operators.'“
IRC is based on a client-server model. IRC is made up of networked servers, where thousands of individuals use a “client” (software program) that connects them to an IRC server through an ISP. Several servers linked together make up a network. Once users connect to an IRC server, they can exchange text-based messages and files in real time with others who also are connected to the same network. All IRC users connected to the same channel receive the same message.
