  • Note The Java Server does not receive or dispense a large amount of data. For basic curricula it just transmits a URL string (a few bytes) while for audio-video conferencing data, the server establishes the session but the multimedia data is transmitted on separate channels.
  • The server is very robust and can handle many users
The next page shows the
  • Tango daemon downloaded in the plug-in
  • The Control Applet downloaded from a Web Server
