PC Card

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.”
