Networks Supporting the Way We Live

• The original idea about networks and the Internet
  was about sharing computer resources
  computer-to-computer communications.
• That quickly changed to people-to-people
  communications.
• Early networks were limited to character-based
  information.
• Communications between computers was not common
  nor easy to do.

Converged Networks

• Traditional telephone, radio, television, and

  consolidate these disparate networks onto one
  platform - a platform defined as a converged
  network.
