Terms You Should Know
When you are
introduced
to
a
new
or
different idea, you
must
often learn a
new
set
of
words
to
understand
the
idea.
The
MS·
DOS
operating system is
no
exception.
The
following pages explain
some
terms
you
will
need
to
know
so
that
you
can
read and use
this manual.
Program
Programs, often called application programs, applications,
or
software, are series
of
instructions
written
in
computer
languages.
These instructions are stored in files and tell
your
computer
to
perform a task. For example, a program might tell
your
computer
to
alphabetically
sort
a list
of
names.
File
A file is a collection
of
related information, like
the
contents
of
a
file folder in a desk drawer. File folders, for instance, might con-
tain business letters, office memos,
or
monthly sales data. Files
on
your
disks
could
also contain letters, memos,
or
data.
