PC Card

An expansion interface developed by the Personal Computer Memory Card International Association (PCMCIA). Introduced in 1990 and also known as "PCMCIA cards," PC Cards were plug-in modules that contained devices such as a modem, network adapter, storage drive and cable TV decoder. Routinely plugged into earlier laptops, which had at least one Type II slot, 16-bit PC Cards were superseded by 32-bit CardBus cards and serial-based ExpressCards.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.
