HARDWARE COMPONENTS
Floppy disk drive The floppy disk drive provides an alternative input for loading
operating system software, user files, and fonts to the system
disks. You can also use the floppy disk drive for diagnostics and
to back up resident user files and fonts on 5.25-inch, double-
sided, high-density floppy disks. You cannot use it as an input
source for print jobs.
The floppy disk drive has a total of 1404 available sectors. Sector
configuration is 78 cylinders, 2 tracks per cylinder, 18 sectors per
cylinder, and 512 bytes per sector.
Terminal The terminal consists of two components: the keyboard and the
display as shown in figure 2-3. The keyboard is your means of
communicating with the LPS; the display is the printing system
means of communicating with you. The commands you enter at
the keyboard control functions (such as loading the operating
system, switching between online and offline processing modes,
starting jobs, requesting sample prints, and obtaining accounting
summaries).
