line
line. The specific hardware path over which data is transmitted or received. A line can also
have a process name associated with it that identifies an input/output process (IOP) or
logical device associated with that specific hardware path.
linear load. Electrical loads for which the impedance is constant regardless of the voltage,
so that if the voltage is sinusoidal, the current drawn is also sinusoidal.
line-handler process. See Expand line-handler process or Expand-over-ServerNet
line-handler process.
line interface unit (LIU). A dual-ported unit consisting of two parts: a communications line
interface processor (CLIP) and a line interface module (LIM). An LIU can communicate
with either the primary or the backup processor, providing fault tolerance. When it is a
component of the communications subsystem, an LIU communicates with either
processor through either of a pair of communications interface units (CIUs).
link. In the Open System Services (OSS) file system, a directory entry for a file.
link count. In the Open System Services (OSS) file system, the number of directory entries
that refer to a particular file.
linker. The process or server that invokes the message system to deliver a message to
some other process or server.
link name. In the Open System Services (OSS) environment, the filename associated with
a specific file within a directory. The length of a filename, and therefore the length of a
link name, depends on the file system.
listener. The process or server that is notified by the message system that a message from
some other process or server is being delivered.
LIU. See line interface unit (LIU).
LMU. See logical memory unit (LMU).
load. (1) To transfer the HP NonStop™ Kernel operating system image or a program from
disk into a computer’s memory so that the operating system or program can run. (2) To
insert a tape into a tape drive, which prepares it for a tape operation (read or write).
local area network (LAN). A network that is located in a small geographical area and
whose communications technology provides a high-bandwidth, low-cost medium to
which low-cost nodes can be connected. One or more LANs can be connected to the
system such that the LAN users can access the system as if their workstations were
connected directly to it. Contrast with wide area network (WAN)
.
locale. In localization, the definition of the subset of a user’s environment that depends on
language and cultural conventions.
