The IRC (Internet Relay Chat) protocol is a simple, text-based conferencing protocol, involving a number of users spread across a number interconnected servers. These users may chat with other individual users, or may chat with group of users on channels, what other chat systems refer to as rooms or chat rooms.
A typical setup in IRC network involves a single process forming a central point for clients, or other servers, to connect to, performing the required message delivery/multiplexing and other functions.
The server forms the backbone of IRC, providing a point to which clients may connect to talk to each other, and a point for other servers to connect to, forming an IRC network.
