ITPEC FE Subject A October 2024 Question 26
ITPEC FE Subject A October 2024 — Question 26 of 60
Tethering — using a phone to share its mobile Internet with other devices via Wi-Fi, Bluetooth, or USB.
Why not others:
- (a) Dedicated mobile hotspots — a separate hardware device (portable router), not a phone feature
- (b) PPPoE — Point-to-Point Protocol over Ethernet, used for DSL connections
- (d) UPnP — Universal Plug and Play, a protocol for automatic device discovery on a network
Key rule: Tethering = phone shares its cellular data connection with nearby devices.
