Meaning – The term PC card, refers to a credit-card-sized adapter that adds function to a mobile computing device. PC Cards can also be used with other personal computing devices that support them. This type of card was formerly called a PCMCIA Card.
No longer commonly used for memory expansion, the PC card has become the general standard for attaching laptop/notebook computer peripheral devices such as network cards, modems, hard disks, and memory cards for early digital cameras.
Formerly called PCMCIA cards, the PC card used a 68-pin, dual-row connecting interface and is about the size of a credit card. It varies in thickness from 0.13 to 0.64 inches and was originally built around an enhanced 16-bit Industry Standard Architecture bus platform.
Example of usage – “Today, nearly all the functions the PC card interface was designed for are powered by USB devices. The ExpressCard, which replaced the PC Card, has a USB interface.”
