Data Transmission

Data transmission is the movement of data (bits) between at least two digital devices.  Data transmission can be over a short distance (e.g. from your computer to a plugged in device) or over longer distances (e.g. networks).

When data needs to be sent from one device to another, it is important to consider how that transmission is going to occur.

Factors to be considered and agreed between sender and receiver:

  • Method of transmission (how many bits are sent at the same time) – Serial or Parallel
  • Direction of transmission (i.e. one direction or both) – Simplex, Half Duplex or Full Duplex
  • Synchronisation method between the two devices – Asynchronous and Synchronous
