Introduction

Internet Relay Chat (IRC) is an application layer protocol that facilitates communication in the form of text. The chat process works on a client/server networking model. IRC clients are computer programs that users can install on their system or web based applications running either locally in the browser or on 3rd party server. These clients communicate with chat servers to transfer messages to other clients. IRC is mainly designed for group communication in discussion forums, called channels, but also allows one-on-one communication via private messages as well as chat and data transfer, including file sharing.

Client software is available for every major operating system that supports Internet access. As of April 2011, the top 100 IRC networks served more than half a million users at a time, with hundreds of thousands of channels operating on a total of roughly 1,500 servers out of roughly 3,200 servers worldwide. IRC usage has been declining steadily since 2003, losing 60% of its users (from 1 million to about 400,000 in 2012) and half of its channels (from half a million in 2003).

An IRCd, short for Internet Relay Chat daemon, is server software that implements the IRC protocol, enabling people to talk to each other via the Internet (exchanging textual messages in real time). It is distinct from an IRC bot that connects outbound to an IRC channel.

The server listens to connections from IRC clients on a set of TCP ports. When the server is part of an IRC network, it also keeps one or more established connections to other servers/daemons.

The term ircd originally referred to only one single piece of software, but it eventually became a generic reference to any implementation of an IRC daemon. However, the original version is still distributed under the same name.

Selected biography

Jarkko Oikarinen (born 16 August 1967, in Kuusamo) is the developer of the first Internet chat network, called Internet Relay Chat (IRC), where he is known as WiZ. While working at Finland's University of Oulu in August 1988, he wrote the first IRC server and client programs, which he produced to replace the MUT (MultiUser Talk) program on the Finnish BBS OuluBox. Using the Bitnet Relay chat system as inspiration, Oikarinen continued to develop IRC over the next four years, receiving assistance from Darren Reed in co-authoring the IRC Protocol. In 1997, his development of IRC earned Oikarinen a Dvorak Award for Personal Achievement—Outstanding Global Interactive Personal Communications System; in 2005, the Millennium Technology Prize Foundation, a Finnish public-private partnership, honored him with one of three Special Recognition Awards.
