I

icon --
1. A graphical representation of a file, directory, program, or window. 2. (programming) In FMLI, it is a symbol used to indicate an available function. For example, the caret (^) is an icon displayed in a frame's border to indicate the contents can be scrolled upwards.

icon box --
Window used for arranging the icons corresponding to the applications you have running.

icon font --
The font used in icon labels.

icon label --
The name displayed with the icon.

icon picture --
The graphical image part of an icon.

iconify --
To store a window as a window icon (also called ``minimize''). When you iconify a window, the only indication that it is open is its icon.

ideogram --
(programming) An ideogram is a language symbol usually based on a pictorial representation of an object or concept. An ideogram might or might not have a phonetic value.

implicit focus --
The behavior of the window manager when you can make a window active by moving the pointer onto it. see also explicit focus.

inactive window --
A window that does not currently accept mouse or keyboard input. See also active window.

include file --
(programming) See header file.

indirect blocks --
Data blocks that are not directly referenced by a inode. The inode has three addresses that indirectly reference data blocks.

init --
A general process spawner which is invoked as the last step in the boot procedure. It regularly checks a table that defines which processes should run at what run level.

initial frame --
(programming) The frame, or frames, named as arguments when the fmli(1) command is invoked. Initial frames are displayed automatically when an FMLI application is started, and remain on display in the work area until the FMLI session is terminated.

initialization file --
(programming) A script in which an FMLI developer can define global attributes of an application using the Form and Menu Language. Such things as a transient introductory frame, a customized banner line, colors for various display elements, and restrictions on user access to the system can be defined. An initialization file is optional, but if one is written, it must be named as an argument when fmli(1) is invoked.

inode --
The internal representation of a file, showing disk layout, owner, type (see file), permissions, access and modification times, size and the number of links. Each inode has a unique decimal identifier.

input focus --
(programming) To have the cursor on a particular field, designating that field as ``next.''

instance --
1. (programming) A specific realization of a widget; one particular widget as opposed to a class of widgets. 2. An actual occurrence of an object which is manipulated by a management protocol such as SNMP and SMUX.

instance name --
(programming) The title of a window. This might have been changed to be different from the generic class name that windows of its type usually have.

intent logging --
A circular logging scheme that records pending changes to the VXFS filesystem structure. These changes are recorded in an intent log.

Internet --
The collection of interconnected networks that grew out of ARPANET, the Defense Advanced Research Projects Agency network, and that use TCP/IP to communicate to function as a single cooperative network.

Internet Protocol (IP) address --
An IP address is a unique number that identifies each host in a network. Every IP address is a 32-bit number that is usually broken down into four pieces called octets, with 8 bits per octet.

internetwork --
Two or more networks connected by an internal or external router.

interpreter --
A program that accepts commands and executes them sequentially. The shells and awk are interpreters. See also compiler.

interrupt --
1. A hardware signal generated by a peripheral device, or a software signal generated because of a software error, which interrupts the normal processing of a program and forces the computer to attend to some service. From the keyboard, interrupts are usually initiated by pressing the <Del> or <Break> key. See also signal. (Note that the term ``signal'' has multiple, overlapping meanings.) 2. (programming) In FMLI, the ability of users to interrupt a process defined in an action or done descriptor can be enabled or disabled through the use of the interrupt descriptor.

Interrupt Request Vector (IRQ) --
A value representing the offset into a list that allows the operating system to find the correct driver to handle requests from a hardware component. With some exceptions, each hardware component must have a unique IRQ. See also interrupt.

I/O --
I/O stands for input/output, the process by which information enters (input) and leaves (output) a computer system.

I/O address range --
A portion of shared memory reserved for communication between the computer operating system and a hardware peripheral.

I/O redirection --
The act of substituting different files for the input and output file descriptors of a process.

IP address --
See Internet Protocol (IP) address.

interprocess communicationIPC --
A set of software-supported facilities that enable independent processes, running at the same time, to share information through messages, a semaphore, or shared memory.

interrupt priority level (IPL) --
The interrupt priority level at which the device requests that the CPU call an interrupt process. This priority can be overridden in the driver's interrupt routine for critical sections of code with the spl(D3) function.

IPX (Internetwork Packet eXchange protocol) --
A Novell® implementation of the XEROX® Networking System (XNS) communications protocol that transports data, or packets, between network devices (such as workstations, servers, and routers).

IPX/SPX (Internetwork Packet eXchange/Sequenced Packet eXchange) --
A set of protocols used to communicate across NetWare® networks. See also IPX (Internetwork Packet eXchange protocol) and SPX.

IRQ --
See Interrupt Request Vector (IRQ).

ISL --
Initial System Load. The first installation of the system.

ISO --
ISO is an acronym for the International Standards Organization. ISO establishes standards in the computing industry for international markets.
