PC Card

An 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 Routinely available on old laptops that had at least one Type II slot, 16-bit PC Cards were superseded by 32-bit CardBus cards and serial-based ExpressCards.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.

Adding Functionality
PC Cards added functionality in laptops just like plug-in boards expanded desktop computers. Because a "PC Card" could refer to both the PCMCIA PC Card or any card inside a PC, people would often say "P-C-M-C-I-A Card."
