Dongle

In computer networking, a dongle is a short network cable that joins a PCMCIA adapter to a network cable. A dongle is used as a security key and its purpose is to ensure that only authorized users can use certain software applications or data. Dongles typically attach to either a RJ-45 connector for Ethernet networking or an RJ-11 connector for dial-up networking. The term "dongle" also has become popular in USB networking, referring to the USB cable that extends from a USB peripheral.
