installer
providing the components of the HP NonStop™ Kernel operating system image 
(OSIMAGE), and containing files that are used after the installation process.
installer. The person who installs the system equipment for a new system. This person also 
installs new equipment when additions are made to the system. This person can install 
software and perform system verification procedures as directed by the system 
planner, configuration planner, or support planner.
instruction processing unit (IPU). A processing unit that executes programs by fetching 
instructions from memory and executing them.
insulated ground. A grounding conductor with a dielectric (low-conductance) insulator 
around it to prevent inadvertent contact with metal conduits.
intelligent SCSI processor (ISP). The ServerNet addressable controller (SAC) that 
controls the small computer system interface (SCSI) bus.
interactive mode. A mode of operation that is characterized by having the same input and 
output device (a terminal or a process) for the session. If a terminal is used, a person 
enters a command and presses Return. If a process is used, the system interface waits 
for the process to send a request and treats the process in the same manner as a 
terminal. Contrast with noninteractive mode.
internal routing. The routing of packets within an HP NonStop™ S-series server.  See also 
external routing.
internal ServerNet fabrics. The fabrics that link ServerNet devices within an HP 
NonStop™ S-series server. See also external ServerNet fabrics.
internal ServerNet X or Y fabric. The X or Y fabric that links ServerNet devices within an 
HP NonStop™ S-series server. See also fabric.
internationalization. The process of designing and coding software so that it can be 
adapted to meet the needs of different languages, cultures, and character sets, with 
the ability to handle various linguistic and cultural conventions. Internationalization 
methods enable the processing of character-based data independently of the 
underlying character encoding, allowing choice among character sets. Sometimes 
referred to as “I18N,” derived from the 18 letters between the initial “I” and the final “N” 
of the word “internationalization.” See also character set.
Internet address. The 32-bit address assigned to hosts that want to participate in the 
Internet using Transmission Control Protocol/Internet Protocol (TCP/IP). Internet 
addresses are an abstraction of physical hardware addresses, just as the Internet is an 
abstraction of physical networks. As assigned to the interconnection of a host to a 
physical network, an Internet address consists of a network portion and a host portion. 
See also IP address.
Internet control message protocol (ICMP). A maintenance protocol in the Transmission 
Control Protocol/Internet Protocol (TCP/IP) suite that is required in every TCP/IP
