Instant messaging, ICQ, and IRC are three commonly used types of internet chatting. Instant messaging allows private or group chats between users, with AOL Instant Messenger being a popular platform. ICQ assigns unique user numbers for identification and communication between two or more users. IRC is designed for group discussion in channels but also allows private chats, running on separate networks like Undernet, EFnet, and DALnet.
