QMS Memory

written and read more quickly than on a hard disk, but a RAM disk
loses any information stored on it when the printer's power is turned
off. The frame buffer and spooling buffer are RAM disk clients.
Hard Disk—The QMS 4525 Print System comes standard with a 200
MB internal hard disk. The hard disk serves as secondary storage
places for such items as downloaded fonts and emulations. Hard
disks are also used to increase the amount of collation that can be
accepted and provide a secondary storage area for spooled data.
SCSI-2 (Small Computer System Interface)—The printer's SCSI-2
port allows you to connect up to 6 external SCSI hard disks, providing
storage for fonts, emulations, and other files.

Non-volatile Memory—The options you select in your printer's Con-
figuration menu such as emulations, memory settings, and input bins
are saved to non-volatile memory. This means that when you turn off
your printer, you do not lose this information.
Volatile Memory—This type of memory is lost when the printer loses
power. For example, most RAM is volatile.
Physical Memory—The physical memory on your printer is equal to
the amount of RAM installed.
Virtual Memory—Virtual memory extends the effective size of the
printer's memory by using a disk file or swap file to simulate additional
memory space. It enables the hard disk to accept data swapped from
RAM to free temporarily the RAM for other tasks.
Spool (Simultaneous Print Operations On Line)—Spooling is tem-
porary storage to hold print jobs until the printer is available to pro-
cess them.
