Bluetooth Dongle

A dongle is a small hardware device that connects to a computer to authenticate an item of software.
Dongle may also refer to something that plugs into a computer and converts a small (often proprietary) port or plug into a larger standard plug. Dongles tend to consist of two connectors that are attached to one another by a length of cable that that hangs (dangle) from a laptop computer. For example:
* A jack wired to a small edge connector on a Type I or II PCMCIA card, typically an 8P8C modular connector for an Ethernet cable or RJ11 jack for a telephone cable. This type of dongle has no copy prevention purpose. PCMCIA card dongles are notoriously fragile and unreliable. They are falling out of favour as more laptops include built-in Ethernet and modem sockets.
* USB adapters, such as for memory cards.
* Other USB devices, primarily flash memory drives, used only for data storage (as opposed to USB Hardware Token Devices).
* The word has also been applied to Bluetooth, Wi-Fi antennas and Infrared transceivers.
* It is also been used to refer to ATI CrossFire Interconnects
