Bluetooth

Bluetooth is a type of wireless technology that allows electronic devices, like smartphones and computers, to connect to each other without any cables. Picture it like a tiny invisible string connecting your devices together, like a marionette puppet show. You can use Bluetooth to transfer files and audio, like music, from one device to another. Plus, it’s a power saver too; it only uses a tiny fraction of the energy that your device does, so you don’t have to worry about it draining your battery. Fun Fact: Bluetooth was named after a 10th-century Scandinavian king, Harald Bluetooth, who united Denmark and Norway.
