Explanation by: Admin
Bluetooth is a wireless technology that allows electronic devices to exchange data over short distances using radio waves.

It typically works within a range of 10 meters (33 feet), but advanced versions can reach up to 100 meters.

Common uses include wireless headphones, file transfers, smartwatches, and IoT devices.

Bluetooth operates on the 2.4 GHz frequency band and uses low power consumption, making it ideal for mobile devices.


Other Options:

USB (A) – A wired technology for data transfer.

Modem (C) – A device that connects computers to the internet.

WiFi (D) – A wireless technology for internet access, but it works over longer distances than Bluetooth.
