PC Card - PCMCIA
PCMCIA stands for Personal Computer Memory Card International Association, the group of companies that defined and developed the standard. While this acronym did clearly describe the original intentions of the organization's standard, it was difficult to say and remember, and was sometimes jokingly referred to as "People Can't Memorize Computer Industry Acronyms". Later PCMCIA was rebranded to simply PC-Card. PC-Cards were superseded by ExpressCards in 2003, laptops manufactured after this time are more likely to have ExpressCards.
