PC Card dongle - Computer Definition
A device used to couple a network or telephone cable to a PC Card (PCMCIA). The dongle provides a way of adding RJ-45 and RJ-11 jacks to cards that do not have the jacks built in. Since PC Cards are thin, the cards that contain the jacks either have them protruding beyond the card or use an XJACK connector, a thin jack that slides in and out of the card. See hardware key.
