Why PCMCIA Type I, II, III cards are required?
Notebook has two PC Card slots (also known as PCMCIA card slots). These slots accept Type I, II, and III cards.
PC Cards are now used in many diverse applications including several types of RAM memory, pre-programmed ROM cards, modems, sound cards, floppy disk controllers, hard drives, CD ROM and SCSI controllers, LAN cards, to name a few.
The PC Card standard has a 68-pin interface between the peripheral card and the socket into which it is inserted. It defines three standard PC Card form factors, called Type I, Type II and Type III. All PC Cards are of the same length and width. However, they differ only in thickness.
For changing most cards the laptops need not be restarted as they support hot-swapping.
