one-to-one (communication)

One-to-one in communication is the act of an individual communicating with another. In Internet terms, this can be done by e-mail but the most typical one-to-one application in the Internet is instant messaging as it does not consider many-to-many communication such as a chat room as an essential part of its scope. This is however not logical, as it also considers presence information an essential part of its scope, and announcing presence is a many-to-many operation.
