Say what Bluetooth is doing
Tell Bluetooth from Wi-Fi, and know which one your headphones use.
Bluetooth joins two devices straight to each other across a few feet. Headphones, a keyboard, the car.
It carries no internet. Wi-Fi reaches the world; Bluetooth reaches the room.
Key points
- Bluetooth joins two devices directly, across a few feet
- It carries no internet, so it keeps working when the internet does not
What to remember
- Pairing is an introduction. They remember each other afterward.
- Bluetooth reaches the room. Wi-Fi reaches the world.
Try this
Open Bluetooth on your own phone and read the list. Every name is something you once introduced it to.
