How does online chat work?
The technologies that allows users to converse in real time via typed messages
are the chat servers and the chat clients. These special
servers allow the messages to be quickly received and posted so that the chat clients can receive the messages
and display them in the window on the users' computers.
Fortunately, most chat clients are relatively inexpensive shareware programs,
and there are a number of chat servers that let the user connect to them for free. Online chat could be an alternative
to meeting in a traditional classroom. While all of the participants would still be able to freely converse with
one another, they would carrying on the conversation from the comfort of their own home, thus avoiding the expense
and inconvenience of traveling to another place.
