2. What is Video Conferencing? Just like the telephone, except you can see who you are talking to. There is no privacy issue, since you can leave it turned off, just like the telephone. You can talk to one or many other people at the same time, just as with the telephone. It is NOT video broadcasting.

7. Video Conferencing Systems 1. Software-based Generally slow and non-standard; not very satisfactory. Examples: Microsoft NetMeeting, White Pine CUSeeMe. 2. Hardware-based, plug into PC USB Port. Newest approach; will become ubiquitous Examples: Polycom ViaVideo, VCON ViGo. 3. Hardware-based, PCI-bus cards install inside PC. Added features and controls, beyond USB systems. Examples: Zydacron Z340, VCON Escort 25. 4. Hardware-based, standalone, no PC involved. Easiest to use, best quality. Examples: Polycom Viewstation 128, VCON Falcon
