IRC (Internet Relay Chat)

Internet Relay Chat (IRC) is a protocol that enables real-time text communication across the internet. It allows users to join designated chat channels or rooms to discuss topics collectively, or send private messages to individuals. IRC operates on client-server architecture, where users connect to IRC servers using specialized software called clients. It has been widely used for group discussions, support communities, and collaborative projects since the late 1980s. Its design emphasizes simplicity, immediacy, and openness, making it a foundational tool for online communication and community building.
