Data Transmission
Cards in this deck (7)
- 1Transmitting Data-The direction of the data transmission (i.e. in one direction only or in both directions)
-The method of transmission (how many bits are sent at the same time)
-The method of synchronisation between two devices - 2Simplex, Half-Duplex & Full Duplex-Simplex data transmission is in one direction only
-Half-Duplex transmission is in both direction but not at the same time
-Full Duplex data transmission is in both directions simultaneously - 3Serial Transmission-Serial Transmission is one bit at a time
-Devices that use Serial Data Transmission are modems, mice and keyboards - 4Features Of Serial Data Transmission-Data is transmitted one bit at a time over a single cable
-Cable is therefor cheaper
-Serial Transmission can be used over large distances - 5Parallel Transmission-Sends 8 bits at a a time
-Devices that use Parallel Transmission are printers that plug straight into the back of 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 (interface) can corrupt the data
-Less Complexity - It is easier to add this technology - 7—
