IOP
IOP. See input/output process (IOP).
IP. See Internet protocol (IP).
IP address. An address that uniquely identifies a specific host system within a network to
the Internet protocol (IP). An IP address consists of two parts: a network address,
which identifies the network, and a local address, which identifies the host within the
network. IP routes data between source and destination IP addresses.
IPC. See interprocessor communications (IPC).
IPU. See instruction processing unit (IPU).
ISO. International Organization for Standardization. ISO is an international body that drafts,
discusses, proposes, and specifies standards for network protocols. ISO is best known
for its seven-layer reference model that describes the conceptual organization of
protocols.
ISO is sometimes called the International Standards Organization. Although ISO is the
official abbreviation, it does not correspond to the organization’s name in any
language.
ISO 646. An ISO standard for representing characters in languages based on the Roman
alphabet. Like ASCII, ISO 646 uses only 7 bits of each 8-bit byte to represent data.
Contrast with ISO 8859.
ISO 8859. A series of ISO standard 8-bit code sets used to represent languages based on
many alphabets, including Roman, Greek, Cyrillic, Hebrew, Turkish, and Arabic. The
ISO 8859 code sets are used in international applications that must be data
transparent. ASCII is a subset of each of the ISO 8859 code sets.
ISO 10646. A universal coded character set that represents all characters and symbols from
all commonly used scripts and languages.
ISO/IEC-conforming POSIX.1 application. An application that both:
•
Uses only the facilities described in ISO/IEC IS 9945-1:1990 and approved
conforming language bindings for any ISO or IEC standard
•
Is documented as using only those facilities and approved conforming language
bindings
isolated ground. A grounding conductor that directly connects the equipment ground
through an isolated ground-type receptacle with the power system grounding point
without any intermediate grounding points.
isolation transformer. A transformer containing electrostatic shields between the primary
and secondary windings, with no direct electrical path between the primary and
secondary windings.
