supplementary group ID
supplementary group ID. An Open System Services (OSS) process attribute that is used
to determine the file access permissions for the process.
support planner. The person who creates the operational environment for the system and
is responsible for the support of the system. This person creates the startup and
shutdown files, performs replacement operations, and prepares the system for
upgrades and additions.
surge. An increase in the amplitude of source voltage of short duration.
SUT. See site update tape (SUT).
SVID. The System V Interface Definition for UNIX, published by AT&T.
SVR4. System V Release 4, a specific implementation of UNIX. See also System V.
SWAN concentrator. See ServerNet wide area network (SWAN) concentrator.
SWAN 2 concentrator. See ServerNet wide area network (SWAN) 2 concentrator.
SWAN manager task (SMT). A manager task that is provided as part of the wide area
network (WAN) subsystem. The SMT runs in each communications line interface
processor (CLIP) and provides a variety of management functions such as
coordinating data link control (DLC) and diagnostic task downloads.
SWID. The software identification tool invoked by the SYSGENR program that audits file
identification information about your software.
switch mode power supply. A computer power supply that uses a pulse-width modulation
switching inverter and nonlinear current draw characteristics. Switch-mode power
supplies are widely used because of their small size and efficiency.
symbol. (1) The symbolic name of a value, typically a function entry point or a data location.
In the context of loadable libraries, symbols are defined in loadfiles and referenced in
the same or other loadfiles. (2) Within the ServerNet architecture, the nine or more bits
that encode 8-bit data and protocol commands.
symbolic link. In the Open System Services (OSS) file system and Network File System
(NFS), a type of special file that acts as a name pointer to another file. A symbolic link
contains a pathname and can be used to point to a file in another fileset. Symbolic
links are not included in ISO/IEC IS 9945-1:1990. Contrast with hard link.
symbolic reference. An occurrence in code or data of the value of a symbol. The symbolic
reference is bound (resolved and made usable) by assigning to it the value of a
definition of that symbol. The symbol value is normally the address of a function or
variable named by the symbol. In position-independent code (PIC) loadfiles, symbolic
references occur only in data.
symbols region. See Inspect region.
