Video conferencing works much like audio conferencing.
The differences are that the users are able to see each other -- and for this a webcam is needed by all parties -- and that depending upon the service used, multiple people can see and be seen at the same time.

Audio conferencing is a connection between two computers that requires participants to have a microphone and speakers.
Using an instant messaging program, such as America Online Messenger (AOL), or an audio conferencing software, such as Skype, users speak into the microphone and the dialogue is heard through the speakers of the other users.
