Some dongles work as a key that unlocks certain software. Manufacturers provided the dongle to prevent pirating of their product or to ensure the owner only operated it on one computer at a time. However, a more common use is as an adapter temporarily connecting a device to a computer.

A dongle provides wireless or Bluetooth capabilities to devices that do not have built-in adapters.

As with other types of dongles, there are connections and electronic hardware that ensure the controller functions with the computer just as it does with the original console.Learn more about Computers & Hardware
