On the Internet, chatting is talking to other people who are using the Internet at the same time you are. Usually, this “talking” is the exchange of typed-in messages and a group of users who take part from anywhere on the Internet. Chats can be ongoing or scheduled for a particular time and duration.
Most chats are focused on a particular topic of interest and some involve guest experts or famous people who “talk” to anyone joining the chat. Transcripts of a chat can be archived for later reference.
