Bluetooth
What is "Bluetooth"?
Bluetooth is the transmission of data via radio waves.
Bluetooth was named after the medieval king of Denmark and Norway Harald Bluetooth.
How does it work? Let's say you have a Smartphone and you talk to your friend about the last holiday you had together and show them some photos of it. They say they would like one of the group pictures. So you activate the Bluetooth on your Smartphone and your friend activates the Bluetooth on their smartphone and you then send the photo via Bluetooth aka these radio waves to them.
