Network Interfaces & Communication Protocols
A network interface protocol is an agreed upon language that includes words, syntax, encoding, and the link speed at which information is communicated between two or more devices. Devices and computing subsystems are interconnected through interfaces based on specific protocols. An interface refers to the connecting point between two adjacent entities. A protocol defines rules to be complied with for exchanging information on the connecting point.
An interface protocol is a specification that defines how data is delivered and interpreted. An example of this is when two pieces of separately manufactured equipment can effectively communicate with each other without having previously discussed their specific engineering concepts.
Data can successfully be delivered over any of the following interface protocols, however, depending on your system requirements one protocol may be more advantageous based on data throughput, latency, security, redundancy, interoperability, or a combination of parameters.
