A: A dongle is a security hardware key that protects copyright and prevents software piracy and is used with the Speed Step software package. It is attached to your computer or server via the USB or parallel port. Dongles which affix to the parallel port are either black (network), white (standalone) or yellow (standalone). Dongles which affix to the USB port are distinguishable by number. Network dongles begin with GB1SW, standalone begin with GB2SW. The use of the dongle confirms that you are the authorised user of the software. Dongles are common with commercial CAD software. They do not interfere with security arrangements of networks.
