- 1Data TransmissionsAgreed Factors
1. The direction of the Data Transmission
(In one direction only or both directions)
2. The method of Transmission (How many bit are sent at the same time)
3. The method of synchronization between the two devices
-Asynchronous (grouped together)
-Synchronous (Continuous stream) - 2Duplexes-Simplex data transmission is one direction only.
-Half duplex is both directions but not at the same time.
-Full Duplex is both directions simultaneously. - 3SimplexPrinter
- 4Half DuplexPhone
Walkies - 5Full DuplexConversation between people
- 6Serial TransmissionSerial Transmission is one BIT at a time, devices that use this are mice, keyboards and modems.
- 7Parallel TransmissionsParallel Transmissions sends 8 bits at a time. Examples that use a parralell Transmissions are things that can be plugged into a computer.
- 8Features of serial Data TransmissionData is transferred
one bit at a time over a single cable.
Cable is cheaper as a result.
Can be used over a large distance. - 9Features of parallel data transmission- Speed- Bits are sent in parallel so more bits are sent at one time.
-Cable length - cross talk (interface) can corrupt
