Question
Which of the following can a user utilize to share their mobile phone connection with their laptop?
- A. IR
- B. NFC
- C. Wi-Fi Direct
- D. Tethering Correct
Explanation
Tethering, also called a mobile hotspot, shares the phone's cellular data connection with other devices such as a laptop over Wi-Fi, Bluetooth or USB. NFC and IR are very short-range technologies used for pairing, payments or remote control, not for sharing an internet connection. Wi-Fi Direct connects two devices to each other for data transfer but does not by itself share the phone's internet connection.
