base computing platform
independent. A component failure in one processor has no effect on any other
processor.
base computing platform. The minimum software implementation that is the foundation for
the X/Open common applications environment (CAE).
base enclosure. An enclosure that is placed on the floor and can have other enclosures
stacked on top of it. A base enclosure is installed on a frame base. Contrast with
stackable enclosure.
base profile. In an X/Open compliant system, a minimum set of software components
required to create a common applications environment.
battery load. The electrical current drain imposed on a battery.
BEB. See back-end board (BEB).
BIND. A program invoked during system generation that creates TNS object (file code 100)
system code files and system library files.
Binder. A programming utility that combines one or more compilation units’ TNS object
code files to create an executable TNS object code file for a TNS program or library.
Used only with TNS object files.
Binder region. The region of a TNS object file that contains header tables for use by the
Binder program.
binding. The operation of collecting, connecting, and relocating code and data blocks from
one or more separately compiled TNS object files to produce a target object file.
BIST. Built-in self-test.
bit-synchronous. A type of Open Systems Interconnection (OSI) Layer-2 protocol that uses
synchronous transmission but does not require a character code to define terminal and
line control sequences.
block. A grouping of one or more system enclosures that an HP NonStop™ S-series
system recognizes and supports as one unit. A block can consist of either one
processor enclosure, one I/O enclosure, or one processor enclosure with one or more
I/O enclosures attached.
blocked signal. A programmatic signal that is currently in the pending signal mask of a
process and, when generated, is not delivered to the process because of the signal
mask setting. Some signals cannot be blocked.
block special file. In the Open System Services (OSS) environment, a device that is
treated as a file for which all input or output must occur in blocks of data. Traditionally,
such files are disk or tape devices. Block special files provide access to a device in a
