Bluetooth is a wireless technology created in 1994 that allows computers, phones and other devices to talk over short distances with a range of roughly 100 meters. Bluetooth uses radio waves, and is designed to connect to each other and be a secure and inexpensive way of connecting and exchanging information between devices without wires. This is useful if you are wanting to send some media or a certain file which isnt that large to another device in close range.
