Final answer:
The two criteria used to select a network medium for a network are the distance the medium can carry a signal and the environment where the medium is to be installed.
Step-by-step explanation:
The two criteria used to help select a network medium for a network are:
- The distance the selected medium can successfully carry a signal
- The environment where the selected medium is to be installed
For example, if a network needs to cover a large physical area, a medium like fiber optic cable may be chosen for its ability to transmit data over long distances without signal degradation. Additionally, if the network will be installed in a harsh environment with extreme temperatures or high humidity, a medium like coaxial cable may be selected for its durability.
