IRC

IRC, or Internet Relay Chat, is an early online communication system that allows multiple users to join shared chat rooms or channels to send real-time text messages. Think of it as a digital group conversation platform where people can discuss topics openly or privately. It operates over the internet using a client-server model, enabling users to connect via specialized software called IRC clients. Despite being one of the first online chat systems, IRC remains popular for community building, collaborative projects, and information exchange due to its simplicity and real-time interaction.
