Linux
Linux. Linus Torvald’s version of the UNIX operating system. See also
http://www.linux.org.
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).
loadable library. A loadfile that offers functions and data to other loadfiles. In this manual,
dynamic-link libraries and hybrid shared run-time libraries are libraries. A library cannot
normally be invoked externally; for example, by a RUN command. Instead, it is invoked
by calls or data references from client loadfiles.
loader. A programming utility that transfers a program into memory so it can run. The
mechanism that brings loadfiles into memory for execution, maps them into virtual
address space, and resolves symbol references among them. Synonyms include
run-time loader and run-time linker. The loader for TNS and for TNS/R native programs
and libraries that are not position-independent code (PIC) is part of the operating
system. For PIC loadfiles, a loader called RLD works with the operating system to load
programs and libraries.
loadfile. An executable object code file that is ready for loading into memory and executing
on the computer. Loadfiles are further classified as executable programs (containing a
main routine at which to begin execution of that program) or executable libraries
(supplying routines or variables to multiple programs or separately loaded libraries). A
TNS code file might be both a loadfile and a linkfile. Native code files are never both.
Contrast with linkfile
.
loadList. A list of all the libraries that must be loaded for a given loadfile to execute. A
loadfile’s loadList includes all the libraries in the given loadfile’s libList plus all the
libraries in those loadfiles’ libLists, and so forth. It does not include the implicit libraries.
The loadList order is the sequence in which these loadfiles are to be loaded when they
are not already loaded by a previous operation. The loadList of the program includes
all the loadfiles present in the process, in the order they were loaded.
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.
