Bluetooth is a wireless technology standard which allows two way data transfer over short distances (up to around 200m depending on the spec. of the Bluetooth) between electronic devices and computers. Some of the key features include security and the ability to connect devices quickly. Devices such as mobile phones, mice, keyboards, tablet PC's, laptops, desktops, speakers and headsets can all be connected to one another if they feature Bluetooth connectivity. A computer can be Bluetooth enabled by simply connecting a USB Bluetooth dongle adaptor. Updated
