Multimedia communication
Every communication project - be it a f lyer, website,
educational CD-ROM, video clip or magazine - is the
result of a wonderful f usion of social craftsmanship and
technology.
One cannot imagine c ommunication without multimedia.
Just as much as multimedia always involves
communication.

Computer-Based Audio Conferencing
• In computer-based audio conferencing, computer
conferencing in the conjunction of audio conferencing
occurs.
• Computer conferencing and audio conferencing are
relatively n ew technologies, each being increasingly
adopted
by educational
institutions to
support
administrative tasks, to network teachers, staff, students
and academics, to deliver courses, and t o f acilitate
curricular activities.

Streaming Audio/Video
• It's a method of delivering an audio/ video signal t o your computer over the Internet, and differs f rom the "normal"
method of receiving Internet audio/video in one important
way.


Instead of having to download a ".wav", ". au―, ―.mp4‖ or other type of f ile completely before being able to listen or see it, you c an observe audio/video as it arrives at your
computer, and therefore do n ot have to wait f or a
complete download (which would be difficult with a live
broadcast anyway!).
