Executive Summary

The Internet is a worldwide network of computer networks. Computers can send messages to each other via the Internet (email is the most familiar example). However, audio can also be digitized and passed between computers just like any other data type. In fact, many Web sites are now sound-enabled. IP telephony uses the Internet to send audio between two or more computer users in real time, so the users can converse.
