Video Description

WAN, Circuit vs Packet Switching and Transmission Media This lesson covers different Wide Area Network (WAN) technologies, properties and applications. WANS allow us to connect multiple local area networks (LANs) over a larger geographical region. WANs use the following technologies:

  • Circuit: connect as needed (such as ISDN or phone lines); no buffering needed
  • Packet: this is shared and always on, the bandwidth is shared.

WANS also use the following transmission media: - Cables

  • Phone lines
  • Cable lines
  • Fiber optics
  • Wireless

    • Radio waves/ infrared
    • Satellite
    • Cellular
