Type
Refers to the physical size of the PC card. There are three types of
cards that have the same length and width, 54 x 85.6 mm (2.13 x
3.37 in.). The cards differ in thickness in the center, but have
identical thickness at the connector end and along the rails. This lets
you use all three types in the same PCMCIA slot, if the slot is thick
enough in the center.
