A memory client is a user of a block of memory dedicated to a specific function. Each
memory client controls certain features. When insufficient memory is allocated to a
specific client, the features it controls may not be accessible.

Some printers designate one or two memory clients to receive all the excess, or
unassigned memory. On your QMS 3260/4032 Print System excess memory is
distributed among all the memory clients.

Storage is a device in (or on) which information can be kept. On QMS printers, there
are three main types of storage—ROM, RAM, and hard disks. ROM stores read-only
data, RAM represents temporary storage, and hard disks hold information on a more
permanent basis (see the following definitions).

This type of memory contains data and/or machine-executable instructions that can
be read but not modified. This information is not lost when the printer’s power is
turned off.

RAM is the memory your printer uses to perform each task. It can be written to and
read from. Once a task is complete, the memory is free again to be used for another
file. This memory is volatile, so if your printer loses power while a file is being sent,
you must resend the file. The number and type of features you can run on your printer
simultaneously depend on the amount of RAM you have and how that RAM is distrib-
uted. Your QMS 3260/4032 comes with either 16 or 32 MB of RAM, and it is upgrad-
able to 384 MB by adding Single In-line Memory Modules (SIMMs).

Hard disks are memory devices that are termed secondary storage (with respect to
RAM which is termed primary storage). Hard disks are used as holding areas for data
to be loaded into RAM and are also used as overflow areas for data too large to fit into
available RAM. Any data undergoing a process by a microprocessor must reside in
RAM. Any data waiting to be processed can reside on a hard disk, but must be trans-
ferred to RAM when required.
