The principal use of online chat rooms is to share text or graphic based information with other users in real time. A chat room can either be a dedicated website or part of a website that offers users a platform to freely communicate with other users who share common interests.
Chat rooms typically do not require the installation of any applications. Text is instantly displayed in a conversation log after the user sends it. Chat room users require a unique username and password for successful registration; however, some chat rooms allow users to chat anonymously. Some websites provide a chat support line that allows users to initiate support sessions with representatives in real time.
