local area network (LAN)
local area network (LAN). Any physical network technology that operates at high speed
(usually from tens of megabits per second to several gigabits per second) over short
distances (up to a few thousand meters).
Netscape. See browser.
NonStop Kernel. The HP operating system, which consists of core and system services.
The operating system does not include any application program interfaces (APIs).
NonStop Servlets for JavaServer Pages (NSJSP). NonStop Servlets for JavaServer
Pages (NSJSP) are platform-independent server-side programs that programmatically
extend the functionality of web-based applications by providing dynamic content from a
webserver to a client browser over the HTTP protocol.
nowait mode. In Guardian file-system operations and in some APS operations, the mode in
which the called procedure initiates an input/output (I/O) operation but does not wait for
it to complete before returning control to the caller. In order to make the called
procedure wait for the completion of the operation, the application calls a separate
procedure. Compare wait mode.
Open System Services (OSS). An open system environment available for interactive or
programmatic use with the NonStop Kernel operating system. Processes that run in
the OSS environment use the OSS application program interface (API); interactive
users of the OSS environment use the OSS shell for their command interpreter.
OSS applications. POSIX compliant applications.
OSS. See Open System Services (OSS).
packet. The unit of data sent across a packet-switching network. While some Internet
literature uses it to refer specifically to data sent across a physical network, other
literature views the Internet as a packet-switching network and describes IP datagrams
as packets.
PATHMON. The central controlling process for a NonStop TS/MP application.
Pathway. The former name of NonStop TS/MP, a product providing transaction services for
persistent, scalable, transaction-processing applications.
physical layer. Layer 1 in the OSI Reference Model. This layer establishes the actual
physical connection between the network and the computer equipment. Protocols at
the Physical Layer include rules for the transmission of bits across the physical
medium and rules for connectors and wiring.
process. A running entity that is managed by the operating system, as opposed to a
program, which is a collection of code and data. When a program is taken from a file
on a disk and run in a processor, the running entity is called a process.
