  1. 1Description of packet switchingTransmission modes are the ways devices on a network communicate & transmit data
  2. 2Advantages of packet switching- Serial -
    Good over large distances
    - Parallel -
    Faster because more bits transferred per second
  3. 3Disadvantages of packet switching- Serial -
    Complex because data has to be broken into individual bits
    - Parallel -
    Only for shorter distamces eg 5 metres
  4. 4Simplex with exampleData that can only be sent one way
    Remote to a TV
  5. 5Half duplex with exampleData that can be sent both ways but only one at a time
    Walkie Talkies
  6. 6Full duplex with exampleData that can continuously be sent in both directions
    Mobile phone
  7. 7Serial and parallel description- Serial -
    Bits of data are transferred one at a time over a wire
    - Parallel -
    Bits of data are transferred simultaneously - a whole byte can be transferred at the same time
  8. 8Benefit and limitations of above- Serial benefit -
    Good over large distances
    - Serial limitation -
    Complex as data has to be broken into individual bits
    - Parallel benefit -
    Faster because more bits can be transferred per second
    - Parallel limitation -
    Only for shorter distances eg 5 meters
