MOUNT The process of preparing a disk device for use.
NON-SELF-CON-
FIGURING DISK
A disk drive that must have a specific disk driver program made for it so it
can communicate with AMOS.
PHYSICAL
ADDRESS
A Winchester controller board has a certain number of fixed addresses,
or ports, to which Winchester technology disk devices may be physically
attached by cables. When the system boots, AMOS tells the controller
which disk drive is associated with address 0, which is associated with
address 1, and so on. Then the devices are given names, and similar
devices are given numbers.
PHYSICAL
UNIT/DEVICE
A physical disk device includes one or more magnetically sensitive disks,
and read/write heads to record and read back data recorded in tracks on
the disk(s).
QUEUE A "waiting list". For example, when printing files, a queue is used so the
files sent to the printer do not print all at the same time, but rather in an
orderly way—first come, first served.
RE-ENTRANT A program is
re-entrant when it can be used by more than one user at a
time, and is therefore able to be loaded into System Memory, where it
can be shared by all users.
RE-USABLE A program is
re-usable when it can be interrupted during its operation,
and then resumed again, or when it can be run again after it has run.
Since AMOS is a multi-user system, most of its programs are
re-usable .
Re-usable programs cannot be loaded into System Memory (unless, of
course, they are also Re-entrant).
SAVE The process of transferring a file from user memory (which is temporary)
to a disk (which is permanent).
SELF-CONFIGUR-
ING DISK
A disk drive that uses a "generic" disk driver program rather than a
specific disk driver. For example, a 400 Mb disk and a 80 Mb disk could
use the same generic driver program if they are both self-configuring
disks.
