A device driver allows the operating sys-
tem or a program to interface correctly
with a peripheral such as a printer or net-
work card. Some device drivers—such as
network drivers—must be loaded from
the config.sys file (with a device= state-
ment) or as memory-resident programs
(usually, from the autoexec.bat file). Oth-
ers—such as video drivers—must load
when you start the program for which
they were designed.

Directories help keep related files orga-
nized in a hierarchical, "inverted tree"
structure. Each disk has a "root" directory;
for example, a C:\> prompt normally indi-
cates that you are at the root directory of
hard-disk drive C. Additional directories
that branch off of the root directory are
called subdirectories. Subdirectories may
contain additional directories branching
off of them.
