I-way: A synonym for information superhighway, it usually refers to the Internet as the only example of the highway that is working today.

Icon: A graphical representation of various elements in Windows, such as disk drives, applications and documents. ˜

IEEE: Institute of Electrical and Electronic Engineers. An international professional society that issues its own standards and is a member of ANSI and ISO.

Illustrator: A computer illustration program developed by Adobe Systems, Inc.

Image: The computerized representation of a picture or graphic.

Image Enhancements: Electronic functions, such as shading, highlighting and zooming, that accent an image or portion of an image.

Image Processing: Think of "data processing": it refers to the manipulation of raw data to solve some problem or enlighten the user in some way not possible without the manipulation. So it is with image processing. Digitized images which have been "acquired" (scanned, captured by digital cameras) can be manipulated. The purpose may be simply to improve the image - change its size, its color, or simply to touch-up parts of it. But a more important application of image processing is to compare and analyze images for characteristics that a human eye alone couldn't perceive. This ability to perceive minute variations in color, shape and relationship has opened up applications for image processing in high-speed manufacturing quality control, criminal forensics, medicine, defense, entertainment and the graphic arts.

Image Processor: Device that takes input data and changes it into the proper format for an imaging device _ printer, display, microform, or computer.

Image Resolution: The fineness or coarseness of an image as it was digitized, measured as dots-per-inch (DPI).

Imagesetter: An imaging device specially applied to create type and graphics. Uses either raster or vector techniques to expose photographic paper or film. Contrasted with a character setter, which creates only alphanumeric characters by exposing paper or film through a mask with the shapes of the letters engraved in it.

Import: To merge text and graphics into a document that you are currently creating or editing with the aid of a computer program.

Imposition: Laying out pages in a press form so that they will be in the correct order after the printed sheet is folded. In color reproduction, laying out originals in position in order that all components of a page can be gang scanned in position in one scan (See gang separation).

Indents: The positions where lines of text begin and end within the specified margins.

Independent Graphic: A graphic placed in a publication that is not tied to the text surrounding it.

Industry Standard Architecture (ISA): A computer system that is is built on the Industry Standard Architecture is one that adheres to the same design rules and constraints that the IBM PC/AT adhered to.

Inline Graphic: A graphic that is embedded in a text block or line of text.

Input Resolution: The number of samples taken at the scanner per unit of length when digitizing an image. Input resolution is often set the same as the system resolution. If the image is destined to be resized, however, the scanner resolution is set to accomidate interactive enlargement or reduction of the image at the workstation.

Insert: A printed piece prepared for insertion into a publication or other printed piece. In color separations, the placement of one piece of color into another.

Insertion Point: The place where text will be inserted when you type. The insertion point usually appears as a flashing vertical bar in the application's window or in a dialog box. The text you type will appear to the left of the insertion point, which is pushed to the right as you type.

Instance: A particular occurance of an object, such as a window, module, named pipe, or DDE session. Each instance has a unique handle that distinguishes it from other instances of the same type.

Interface: The hardware and software that enables electronic devices to share information.

Integrated Services Digital Network (ISDN): A high-bandwidth communications service, ISDN combines voice and digital services over a single medium, enabling telephone lines to handle both on a single wire. ISDN permits connections upto 128Kbps. ISDN requires a special adapter for your computer. An ISDN connection is available in most areas of the United States for a reasonable cost, unless you live in New Mexico.

International Standards Organization. (ISO): The organization that produces many of the world's standards. Open System Interconnect(OSI) is only one of the many areas standardized by the ISO.

Internet: The name for a world-wide, TCP/IP-based networked computing community with millions of users worldwide that links government, business, research, industry, and education together.

Internet Protocol (IP): The primary network layer protocol of the TCP/IP protocol suite, IP is probably the most widely used network protocol in the world. IP is responsible for addressing and sending TCP packets over the network.

Internetworking Packet Exchange/Sequenced Packet Exchange (IPX/SPX): Transport protocols used in Novell NetWare networks.

IP Address: Used to identify a node on a network and to specify routing information on an internetwork. Each node of the inernetwork must be assigned an unique IP address, which is made up of the network ID, plus a unique host ID assigned by the network administrator. The subnet mask is used to seperate an IP address into the host ID and network ID.

ISDN: See Integrated Services Digital Network.

ISP: Internet Service Provider. Any organization that will provide Internet access to a consumer, usually for a fee.
