IRC clients are software applications that allow users to connect to Internet Relay Chat (IRC) networks. They provide a platform for real-time text communication, enabling users to join channels, send messages, and interact with others. Popular features include private messaging, file sharing, and customizable user interfaces. These clients can be installed on various devices, including computers and smartphones. Some well-known IRC clients include mIRC, HexChat, and Pidgin. Each client may offer unique functionalities, but they all serve the primary purpose of facilitating communication over IRC networks.
