Interactive command
Interactive command. In DSM, a command entered by a human operator rather than by a
program.
International Organization for Standardization. See ISO.
Institute of Electrical and Electronics Engineers. See IEEE.
Internet. Physically, a collection of packet-switching networks interconnected by gateways
along with protocols that allow them to function logically as a single, large, virtual
network. When written with a capital I, Internet refers specifically to the DARPA Internet
and the TCP/IP protocols it uses.
Internet address. The 32-bit address assigned to hosts that want to participate in the
Internet using TCP/IP. Internet addresses are the abstraction of physical hardware
addresses, just as the Internet is an abstraction of physical networks. Actually
assigned to the interconnection of a host to a physical network, an Internet address
consists of a network portion and a host portion. The partition makes routing efficient.
Internet Protocol. See IP (Internet Protocol).
Internetwork Packet Exchange (IPX). Novell’s protocol for connectionless, internetwork-
wide, packet delivery.
interoperability. The ability of software and hardware on multiple machines from multiple
vendors to communicate meaningfully.
IP address. See Internet address.
IP datagram. The basic unit of information passed across the Internet. An IP datagram is to
the Internet as a hardware packet is to a physical network. It contains source and
destination addresses, along with data.
IP (Internet Protocol). The Internet standard protocol that defines the Internet datagram as
the unit of information passed across the Internet and that provides the basis for the
Internet connectionless, best-effort packet delivery service.
IPX. See Internetwork Packet Exchange (IPX).
IPXMGR process. A HP process that provides the NonStop IPX/SPX subsystem with an
SPI interface to SCF and supports DSM management functions.
IPXPROTO process. A HP process that supports the following protocols on the NonStop
IPX/SPX subsystem: IPX, RIP, SAP, SPX, SPXII, and NCP.
ISO. (International Organization for Standardization) A United Nations organization
established to promote the development of standards to facilitate the international
exchange of goods and services and to develop mutual cooperation in areas of
intellectual, scientific, technological, and economic activity.
