    • Ex: walkie-talkies
  3. Full-duplex transmission
    • Allows data to flow in both directions simultaneously
    • EX: telephone
  4. Switching
    Involves moving the signal from one wire or frequency to another
  5. Circuit switching
    • Type of switching used by telephone systems
    • A dedicated and direct physical connection is made between the caller and the recipient
  6. Packet switching
    • Used by data networks

    • Each packet is sent independently
  7. Packet switching advantages
