What OSI physical layer term describes the physical medium that uses the propagation of light?
- fiber-optic cable
Answers Explanation & Hints:
The OSI physical layer term that describes the physical medium that uses the propagation of light is “fiber-optic cable”. Fiber-optic cables use light signals to transmit data over long distances with high bandwidth and low attenuation. Unlike copper cables that use electrical signals, fiber-optic cables use glass or plastic fibers to transmit light signals. “Goodput” is not a physical layer term, but rather refers to the amount of useful data transmitted over a network after the removal of overhead and error-correction data. “Latency” is the delay between the transmission and receipt of a signal, while “throughput” is the amount of data that can be transmitted over a network in a given amount of time.
