2.23 One-to-one Communication
The IRC (Internet Relay Chat) is a virtual meeting point. There are several "rooms" where people with various interests can chat in a so-called point-to-multipoint- or one-to-many-communication. You can also "rent" an own room and invite others to join you or leave a room at any time. Furthermore, you can talk to people you meet privately at any time and exchange documents or chat in a "secure" one-to-one communication.
Animation 2.23-1 shows an example for a one-to-one communication.
