Cards in this deck (7)
- 1Serial data transmissionBits are sent of one after another one along the same data line
- 2Parallel data transmissionSeveral bits are sent through simultaneously by along separated lines or channels
- 3Who is faster ? Serial or Parallel and why?With the same signal frequency, parallel can be transmitted faster. But in reality, universal serial bus can be sent at higher frequency than parallel transmission line due to the level of technology. Therefore, Serial data transmission is faster.
- 4Problem of parallel data transmissionThe problem of skew. As the transmit distance increase, The data sent simultaneously will be sightly out of synchronised. Therefore, the maximum length of parallel data transmission is 2m.
- 5Problem of serial data transmissionThe problem of crosstalk
E.M. interference of two adjacent channel or parallel wire - 6Synchronised TransmissionAll data transfer are timed to coincide with internal clock pulse
- 7Asynchronised TransmissionData transfer
