A guide's phone and wireless headset talk only to each other, within a few feet, and to nothing else. Which network type is that link?
Select an answer to reveal the explanation.
Short Explanation
The headset is a conversation across an arm's length, not across a city or a continent. You call that small bubble a personal area network. A carrier network, a disk network, and a city network are all far bigger than a phone talking to the headset on the same person.
Full Explanation
A personal area network is the short-range network around one person. A phone and a headset that talk only to each other within a few feet match that type. A wide area network crosses long distances, typically through a carrier, and connects sites. A headset link does not. A storage area network carries storage traffic between servers and disk systems. Audio to a headset is not storage traffic. A metropolitan area network connects locations across a city. Being physically in a city does not make a six-foot headset link a metropolitan network. Exam caveat: if the phone then bridges that audio out to a cellular call, the cellular hop is a different network type than the headset link. The question is about the phone-to-headset path. Operational check: confirm the headset is paired to the phone and that the audio still works with the phone's wide-area radio off. Turn the phone's cellular radio off and confirm the headset audio still works. Pair the headset again if a second phone nearby stole the connection.
