Formatted
Formatted diskettes are "mapped out". When you format a
disk, the disk drive creates divisions ("sectors") on the
diskette, and numbers them. With this, data that is saved
on
a formatted disk can
be
located in,
say,
sector
1,
etc.
Formatting gives your computer the ability to locate data
with precise coordinates
on
each floppy diskette.
Hard
Disk Drive
A hard disk drive (or fixed disk) can store much more
information than a floppy disk drive. A hard drive is made
of many layers of special magnetic media, specifIcally de-
signed to hold high quantities
of
data. As a rough
ex-
ample, installing a
20
MB hard drive in your computer is
like adding
125
floppy disk drives to that same computer.
A hard disk allows you to access information more rapidly,
because you do not have to repeatedly load floppy disk-
ettes.
One note
of
caution - because a hard drive
is
made up
of so many layers
of
specialized magnetic media, it
is
much more delicate. Use care when handling
or
moving a
computer with
an
installed hard drive, and carefully read
all precautions before handling
or
moving any hard disk
drive.
Hardware
Hardware
is
considered to be any part
of
your computer
that you can actually touch (in contrast to software which
is considered to be information stored on magnetic medial
floppy diskettes). Items of hardware include printers, moni-
tors, floppy disk drives, etc.
Hercules/Hercules-Compatible
Hercules
or
Hercules-compatible
is
a monitor display
standard
of
720H x 350V resolution.

refers to the
