Cross References
IBM OS/2 Presentation Manager n. The front-end data manager and user interface for the IBM OS/2 operating system; an example of a graphical user interface.
icon 1. n. A graphic symbol, displayed on a screen, that a user can point to with a device such as a mouse in order to select a particular function or software application. 2. n. A graphical representation of an object (for example, a file or program) that consists of an image, an image background, and a label.
immediate access storage n. A storage device whose access time is negligible in comparison with other operating times.
informatiion appliance n. A computing device that is used to access, manipulate, or transmitinformation but is not traditionally thought of as a computer. Cellular phones and personal digital assistants (PDAs) are examples of information appliances.
input field 1. n. In computer graphics, an unprotected field on a display surface in which data can be entered, modified, or erased. 2. n. A field in a display file into which a user can key in data. An input field is passed from the device to the program when the program reads the record containing that field.
input focus n. The position, indicated on the screen, where a user's interaction with the keyboard will appear.
input/output channel 1. n. In a data processing system, a functional unit that handles transfer of data between internal and peripheral equipment. 2. n. In a computing system, a functional unit, controlled by a processor, that handles transfer of data between processor storage and local peripheral devices.
input/output (I/O) adj. Pertaining to (a) input, output, or both or (b) a device, process, or channel involved in data input, data output, or both.
installation 1. n. In system development, preparing and placing a functional unit in position for use. 2. n. A particular computing system, including the work it does and the people who manage it, operate it, apply it to problems, service it, and use the results it produces.
integrated services digital network (ISDN) n. A digital end-to-end telecommunication network that supports multiple services including, but not limited to, voice and data. ISDNs are used in public and private network architectures.
intelligent agent n. Software that monitors conditions or actions on a network node and contains logic enabling it to respond to these conditions or actions.
interactive 1. adj. Pertaining to a program or system that alternately accepts input and then responds. An interactive system is conversational, that is, a continuous dialog exists between user and system. 2. adj. Pertaining to the exchange of information between a user and a computer.
interface 1. n. A shared boundary between two functional units, defined by functional characteristics, signal characteristics, or other characteristics, as appropriate. The concept includes the specification of the connection of two devices having different functions. 2. n. Hardware, software, or both, that links systems, programs, or devices. 3. v. (Of humans) To talk (as in: "I'm going to interface with the new manager.") 4. v. (Of machines) To connect.
interleaving 1. v. The simultaneous accessing of two or more bytes or streams of data from distinct storage units. 2. v. The alternating of two or more operations or functions through the overlapped use of a computer facility.
internet n. A collection of interconnected networks that use the Internet suite of protocols. The internet that allows universal access is referred to as the Internet (with a capital "I"). An internet that provides restricted access (for example, to a particular enterprise or organization) is frequently called an intranet, whether or not it also connects to the public Internet.
Internet n. The worldwide collection of interconnected networks that use the Internet suite of protocols and permit public access.
Internet address See IP address.
Internet Protocol (IP) n. In the Internet suite of protocols, a connectionless protocol that routes data through a network or interconnected networks and acts as an intermediary between the higher protocol layers and the physical network.
Internet service provider (ISP) n. An organization that provides access to the Internet.
Internet suite of protocols n. A set of protocols developed for use on the Internet and published as Requests for Comments (RFCs) through the Internet Engineering Task Force (IETF).
interoperability adj. The capability to communicate, execute programs, or transfer data among various functional units in a way that requires the user to have little or no knowledge of the unique characteristics of those units.
interrupt 1. n. A suspension of a process, such as execution of a computer program caused by an external event, and performed in such a way that the process can be resumed. 2. v. To stop a process in such a way that it can be resumed.
intranet n. A private network that integrates Internet standards and applications (such as Web browsers) with an organization's existing computer networking infrastructure.
invoke v. To start a command, program, or procedure.
I/O See input/output.
IP See Internet Protocol.
IP address n. The unique 32-bit address that specifies the location of each device or workstation on the Internet. For example, is an IP address.
Iron Mountain n. Permanent "vital records" document storage.
IS (eye-es) (eye-es) n. Information Systems. The department or function that manages the computer installations at IBM sites.
issue n. A formal notification from one group to another that the first is dissatisfied with some action by the other and is prepared to take the matter to the next level of management to resolve the problem. Over time, the term has been extended to cover even minor differences of opinion (as in: "I have an issue with that color."). Similar to concern, exposure, non-concur.
issuer n. In e-commerce, a financial institution that issues payment cards to individuals. An issuer can act as its own certificate authority (CA) or can contract with a third party for the service.
