Packet switching
Cards in this deck (8)
- 1Description of packet switchingTransmission modes are the ways devices on a network communicate & transmit data
- 2Advantages of packet switching- Serial -
Good over large distances
- Parallel -
Faster because more bits transferred per second - 3Disadvantages of packet switching- Serial -
Complex because data has to be broken into individual bits
- Parallel -
Only for shorter distamces eg 5 metres - 4Simplex with exampleData that can only be sent one way
Remote to a TV - 5Half duplex with exampleData that can be sent both ways but only one at a time
Walkie Talkies - 6Full duplex with exampleData that can continuously be sent in both directions
Mobile phone - 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 - 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
