GPR
GPR. See general-purpose register (GPR).
graphical user interface (GUI). A user interface that offers point-and-click access to
program functions.
graphics address remapping table (GART). The scatter-gather table used for graphics
address remapping functions.
ground. A conducting connection, whether intentional or accidental, between an electrical
circuit and either the earth or some conducting body that serves in place of the earth,
such as an underground metal water pipe, structural steel, or a ground rod driven into
the earth. See also earth ground.
grounded. Connected to earth or to some conducting body that serves in place of the earth.
grounded conductor. A system or circuit conductor that is intentionally grounded.
ground fault. Any undesired current path from a point of differing potential to ground.
ground fault interrupter. A device that interrupts the electric current to the load when a
fault current to ground exceeds a predetermined value that is less than that required to
operate the overcurrent protection device of the supply circuit.
grounding conductor. A conductor used to connect equipment of the grounded circuit of a
wiring system to one or more earth-grounding electrodes. See also earth-grounding
electrode.
group. (1) Part of the group, module, slot naming convention for uniquely identifying the
logical location of a component within a system. A group is a subset of a system and
contains one or more modules. A group does not necessarily correspond to a single
physical object, such as an enclosure. For example, an HP NonStop™ S-series
processor enclosure typically includes only one group number, but a modular cabinet
can contain several enclosures that each might belong to different groups. See also
module
. (2) In the Open System Services (OSS) environment, a set of user IDs with
the same group ID.
group database. A database on an Expand node that contains the group name, group ID,
and user names for each group using that node.
group ID. The nonnegative integer used to identify a group of users of an Expand node.
Each user of a node is a member of at least one group. When the identity of a group is
associated with an Open System Services (OSS) process, a group ID value is referred
to as one of:
•
Real group ID
•
Effective group ID
•
Supplementary group ID
•
Saved-set group ID
