PC CardPersonal Computer Memory Card International AssociationPC CardAn earlier expansion interface developed by the Personal Computer Memory Card International Association (PCMCIA). Introduced in 1990 and also known as a "PCMCIA Card," a PC Card was a plug-in module that contained a peripheral component such as a modem, network adapter, storage drive or cable TV decoder. Routinely available on old laptops that had at least one Type II slot, 16-bit PC Cards were superseded by 32-bit CardBus cards and serial-based ExpressCards. See PCMCIA, ExpressCard, CableCARD, CompactFlash and PC Card adapter.
