specifications. The PC Card that has roughly the size of a credit card can be
plugged into a PCMCIA slot. Version 1 specifies cards of Type I with a thickness of
3.3 millimeters, which is conceived mainly for use as external memory. Version 2 of
the PCMCIA specification also defines a card Type II with thickness of 5 mm and a
card of the Type III with a thickness of 10.5 mm. Type II cards can realize devices
such as modems, fax and network interface cards. Type III cards are equipped
with devices that require more space, for example wireless communication
modules or rotary storage media (hard disk drives, for example).

manually configuring the system. The Plug and Play PC requires both a BIOS that
supports Plug and Play and a corresponding expansion card.
