Final answer:
The distance to the nearest power point is not a criteria for selecting a wired communication protocol. Criteria like speed, wiring, simultaneous transmission, device count, and maximum distance are relevant for protocol selection.
Correct option is E. Distance to the nearest power point
Step-by-step explanation:
The question asks which criterion is not relevant when selecting a wired communication protocol. Among the options provided, the distance to the nearest power point is not a criterion for selecting a wired communication protocol. Rather, relevant criteria include attributes such as communication speed, the number of wires per connection, the ability to transmit and receive information simultaneously, the number of devices that need to be connected, and the maximum distance permissible between master and slave devices in a network.
Since communication protocols are more concerned with data transfer and network efficiency, the proximity to a power source is typically a logistical consideration, not directly related to protocol selection.
