exceptions using try, catch, and finally blocks.
Expand
The HP NonStop operating system network that extends the concept of fault tolerance to
networks of geographically distributed NonStop systems. If the network is properly
designed, communication paths are constantly available even if there is a single line
failure or component failure.
expandability
See scalability.
F
fault tolerance
The ability of a computer system to continue processing during and after a single fault
(the failure of a system component) without the loss of data or function.
G
garbage collection
The process that reclaims dynamically allocated storage during program execution. The
term usually refers to automatic periodic storage reclamation by the garbage collector
(part of the runtime system), as opposed to explicit code to free specific blocks of
memory.
graphical user interface (GUI)
Software that provides user control using a graphic display format. GUI software
provides a bit-mapped, icon-oriented, windowing, graphical environment.
Guardian
An environment available for interactive and programmatic use with the NonStop
operating system. Processes that run in the Guardian environment use the Guardian
system procedure calls as their API. Interactive users of the Guardian environment use
the TACL or another HP product's command interpreter. Compare to OSS.
