Glossary

conventional memory
The first 640 KB of RAM. Conventional memory is found in all systems. Unless
they are specially designed, programs run from the Windows Command Prompt
are limited to running in conventional memory.
CPU
Abbreviation for central processing unit. See also microprocessor.
device driver
A program that allows the operating system or some other program to interface
correctly with a peripheral device, such as a printer. Some device drivers—such
as network drivers—must be loaded from the config.sys file (with a device=
statement) or as memory-resident programs (usually, from the autoexec.bat file).
Others—such as video drivers—must load when you start the program for which
they were designed.
DHCP
Abbreviation for Dynamic Host Configuration Protocol, a protocol that provides
a means to dynamically allocate IP addresses to computers on a LAN.
DIMM
Acronym for dual in-line memory module. A small circuit board containing
DRAM chips that connects to the system board.
directory
Directories help keep related files organized on a disk in a hierarchical, "inverted
tree" structure. Each disk has a "root" directory; for example, a
C:\> prompt
normally indicates that you are at the root directory of hard drive C. Additional
directories that branch off of the root directory are called subdirectories.
Subdirectories may contain additional directories branching off of them.
DKS
Abbreviation for dynamic kernel support.
DTK
Abbreviation for Deployment ToolKit.
DMA
Abbreviation for direct memory access. A DMA channel allows certain types of
data transfer between RAM and a device to bypass the microprocessor.
