IBC
IBC. See in-band control (IBC).
ICMP. See Internet control message protocol (ICMP)
identifier. A unique name, for example, TANDEM^FILES^TO^COPY, in the CONFTEXT file
that refers to a text string (one or more file names as given in the CONFAUX file).
When Distributed Systems Management/Software Configuration Manager (DSM/SCM)
encounters an identifier, it substitutes the text string for the identifier.
ideogram. See ideograph.
ideograph. A character or symbol representing a word or idea. Some writing systems, such
as Japanese and Chinese, use thousands of ideographs. An ideograph is sometimes
called an “ideogram.”
IEC. International Electrotechnical Committee. IEC is a professional organization that
creates or adopts standards for computer hardware, environments, and physical
interconnections.
IEEE. Institute of Electrical and Electronics Engineers. IEEE is a professional organization
whose committees develop and propose computer standards that define the physical
and data link protocols of entities such as communication networks.
IEEE 802.3 protocol. Institute of Electrical and Electronics Engineers (IEEE) standard
defining the hardware layer and transport layer of (a variant of) Ethernet. The
maximum segment length is 500 meters and the maximum total length is 2.5
kilometers. The maximum number of hosts is 1024. The maximum packet size is 1518
bytes.
impedance. The total opposition (that is, resistance and reactance) a circuit provides to the
flow of alternating current at a given frequency.
implementation-defined. Not specified by a standard. A correct value or behavior that is
implementation-defined can vary from system to system and therefore might represent
a feature or facility that cannot be ported.
implicit library. A library supplied by HP that is available in the read-only and execute-only
globally mapped address space shared by all processes without being specified to the
linker or loader. See also TNS system library and public library.
implicit library import library (imp-imp). See import library.
implied user library. A method of binding TNS object files that have more than 16 code
segments. Segments 16 through 31 are located in the user code (UC) space but are
executed as if they were segments 0 through 15 of the user library (UL) code space.
This method precludes the use of a user library. Binder now supports 32 segments of
UC space concurrently with 32 segments of UL code space, so the implied user library
method is not needed in new or changed TNS applications.
