Question
Which of the following best represents the purpose of NFC?
- A. Wired connections between several devices
- B. Short-distance wireless connections between two devices Correct
- C. Wireless connections between multiple devices at once
- D. Direct connection of two computers for file sharing
Explanation
NFC (near-field communication) is a short-range wireless technology that works when two devices are brought within a few centimetres of each other, for example to tap-to-pay or pair devices. It is not wired, and its tiny range makes it unsuitable for connecting many devices at once; that is the role of technologies such as Wi-Fi. Direct computer-to-computer file sharing over a cable or network is not what NFC is designed for.
