Introduction
DOS stands for Disk Operating System. People are
about
evenly divided between saying d - 0 - s
or
as one word,
doss
(to
rhyme with hoss).
DOS
is
a collection
of
programs for
your
IBM
Personal
Computer
that
is supplied
to
you
on
the
DOS
Diskette.
These programs process commands
to
let
you
manage
information. They also help
you
manage
the
hardware
resources (for example, the diskette drives and screen)
of
your
computing system. DOS also does some
stuff
inside the machine,
but
since it does it for you, we
won't
describe it in this chapter.
This chapter tells
you
about
starting DOS,
about
the
diskettes and making a copy
of
the DOS Diskette.
Then we will step
you
through examples
of
the DOS
commands
you
will use most often. After you've
learned how
to
use these commands,
you
will probably
want to refer
to
the IBM Personal Computer Disk
Operating
System
book
for more information
on
these
and
other
commands, and on
other
DOS programs.
It
is
important
that
you
copy
your
DOS Diskette.
In
fact, we suggest
you
do
it several times. See
"An
Important
Exercise" for instructions.
