Communication methods for digital systems
Communication methods
- wires and signalling conventions used to transmit data between digital devices – we'll only deal with digital communication – other methods include radio frequency (RF), infra-red (IR), freq. modulation (FSK), optical, etc.
Orthogonal elements of communication methods
- bandwidth – number of wires
- speed – bits/bytes/words per second
- timing methodology – synchronous or asynchronous
- number of destinations/sources
- arbitration scheme – daisy-chain, centralized, distributed
- protocols – provide some guarantees as to correct communication
