structured view of the user ID
ISO/IEC IS 9945-1:1990 as unspecified or implementation-defined and, for symbolic
constants, accept any value permitted by ISO/IEC IS 9945-1:1990.
structured view of the user ID. A view of the HP NonStop™ Kernel user ID, normally used
in the Guardian environment, that consists of either the group-number,
user-number pair of values or the group-name.user-name pair of values.
subnet. See subnetwork.
subnetwork. A physical network within an Internet protocol (IP) network. Each IP network
can be divided into a number of subnetworks. Within a given network, each
subnetwork is treated as a separate network. Outside the network, the subnetworks
appear as part of a single network. The terms subnetwork and subnet are used
interchangeably.
subnetwork address. An extension of the Internet protocol (IP) addressing scheme that
allows a site to use a single IP address for multiple physical networks. A subnetwork
address is created by dividing the local part of an IP address into a subnetwork number
(identifying a particular subnetwork) and a host number (uniquely identifying the host
system within the subnetwork). The terms subnetwork address and subnet address are
used interchangeably.
SUB option. In some Subsystem Control Facility (SCF) subsystems, the designation that
the object name given in a command stands not just for itself, but for the names of all
objects at the next-lower level in the hierarchy. The given object name can stand both
for itself and for the subordinate objects, or it can stand only for the subordinate
objects, depending on the value of the SUB option.
subordinate objects. In Subsystem Control Facility (SCF), objects that are logically
subordinate to other objects. Some subsystems are structured hierarchically, with
objects of one type logically subordinate to (that is, controlled by) an object of another
type. For example, a number of subdevices can be configured on a single line. Some
SCF commands include a SUB option that refers to subordinate objects.
Subscriber Channel (SC). A type of head on a fiber-optic cable in which the pins connect
through a push-pull mating interface.
substate. Further information about the state of a device. The state and substate together
provide information about the current condition of a device or path to a device.
SUBSYS object type. The Subsystem Control Facility (SCF) object type for most
subsystems that use SCF as the user interface.
subsystem. (1) A secondary or subordinate system, usually capable of operating
independently of or asynchronously with a controlling system. (2) A program or set of
processes that manages a cohesive set of Subsystem Control Facility (SCF) objects.
Each subsystem has a manager through which applications can request services by
issuing commands defined by that subsystem. See also subsystem manager.
