IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

Multimedia applications are those programs that integrate more than one media at a time; browsers are the most obvious. However, the term has come to include the use of programs that enable the use of any component that isn’t simple text and static graphics, such as audio, video, animation, virtual reality, conferencing and monitoring.
