- the access to, or connection with, a chat room.

Chat Room
an area on the Internet or other computer network where users can communicate, typically limiting communication to a particular topic.

The primary use of a chat room is to share information via text with a group of other users. New technology has enabled the use of file sharing and webcams to be included in some programs and almost all Internet chat or messaging services allow users to display or send to each other photos of themselves.

Some people who visit chat rooms use them as a place to experience online sex, also known as cybersex or computer love. While not physically able to see their partner, cyber-ers apparently get stimulation by reading x-rated quotes. While many in the media focus on this aspect of chat rooms as it certainly boosts their ratings, it is by no means the only thing chat rooms are used for. It is important that the partakers in such activities do not reveal personal information such as addresses as sexual predators may use cybersex as a tool to stalk chatroom users.

Some visual chat rooms also incorporate audio and video communications, so that users may actually see and hear each other. However, some find these types of environments cumbersome to use and actually an impediment to chatting.
