CNET GLOSSARY: Terms for the techie
A form of synchronous communication that allows users on a network such as AIM or ICQ to initiate chat sessions with others on that network in real time. Currently, several instant-messaging systems are available, but no one is standard; this means that you must be on the same network as the people you wish to communicate with.
