Can anyone explain video conferencing to me?

Videoconferencing in its most basic form is the transmission of synchronized image (video) and speech (audio) back and forth between two or more physically separate locations, simulating an exchange as if the participants were in the same physical conversation. This is accomplished through the use of cameras (to capture and send video from your local endpoint), video displays (to display video received from remote endpoints), microphones (to capture and send audio from your local endpoint), and speakers (to play audio received from remote endpoints) PC requirements are OS:Windows 95, 98, ME/2000, Windows NT 4.0 Workstation or Windows XP. 500 MHz or faster processor High-speed Internet or network connection. Cablemodem, DSL Internet connection 64 MB RAM, 128 MB or more recommended. 50 MB free hard disk space Record/ Play Sound (i.e. a sound card) This is the pc requirement if you have good internet connection, happy mylotting
