- 1Data transmissionsAgreed factors
1. The direction of the data transmission (i.e. in one direction only or both directions)
2. The method of transmission (how many bits are sent at the same time)
3. The method of synchronisation between the two devices - 2DirectionsSimplex data transmission is in one direction only
Half-duplex transmission is in both directions but not at the same time
Full duplex data transmission is in both directions simultaneously - 3Serial transmissionSerial transmission is one BIT at a time
Devices that use serial data transmission are mice, Keyboards and modems - 4features of serial data transmissionsData is transmitted one bit at a time over a single cable.
Cable is cheaper as a result
Can be used over large distance - 5Parallel transmissionsParallel transmissions sends 8 bits at a time. Examples that use parallel transmissions are things that can be plugged into a computer.
- 6Features of parallel data transmission- Speed - bits are sent in parallel so more bits are sent at one time.
- Cable length - cross talk (interference) can corrupt the data.
- Less complex and easier to add to this technology,
