Glossary

adapter

The hardware that connects the computer bus to the 68-pin PC card sockets in the
PCMCIA slot. See also socket.

application programming interface (API)

The set of services that an operating system makes available to programs that run
under it.

binary file

A file consisting of a sequence of 8-bit data or executable code, as distinguished
from files consisting of human-readable ASCII text.

Card Identification Structure

A PC card that complies with the PCMCIA standard. Card Information Structure
(CIS) contains configuration information about the PC card and communicates it to
the computer.

Card Services

The software interface that coordinates traffic among the computer and the PC
cards, sockets, and system resources. See also Socket Services.

dual-port memory

Memory that can be viewed from two different hosts. This memory allows the PCD
card and a host computer to communicate. The memory range marked as dual-port
memory is a common, shared memory area.

enabler

Software used to control PC cards. There are three types of enablers: generic
(which can control many different types of cards), specific (which is designed for a
specific manufacturer’s PC card), and point enabler (which is designed for a
specific manufacturer’s PC card but does not require Card and Socket Services).

MS-DOS mode

Used in reference to a Windows machine when Windows is shut down to access
MS-DOS only. This removes the plug-and-play sytem from a notebook’s memory
and eliminates any conflict between virtual file managers, virtual display drivers,
and other virtual hardware drivers with any other DOS-only software packages.

PC card

Credit-card size, 68-pin add-in cards that were designed to meet PCMCIA standards.
