1. In networking, a software application that allows the user to access a service from a server computer, e.g., a server computer on the Internet or a LAN. 2. A computer, e.g., a desktop computer on a LAN, that is so served.

1. In network topology, a terminal of any branch of a network or an interconnection common to two or more branches of a network. Synonyms junction point, nodal point. 2. In a switched network, one of the switches forming the network backbone. Note: A node may also include patching and control facilities. 3. A technical control facility (TCF. ) 4. A point in a standing or stationary wave at which the amplitude is a minimum. In this sense, synonym null. 5. A data processing facility that provides information processing resources as part of a network. A node may support user application processes, server application processes or a combination of both kinds of processes.

1. In moving picture or television technology, a relatively short, continuous set of frames (often including the associated audio, if any,) stored on a recording medium. Synonyms take, scene. 2. In audio, a short, uninterrupted sound track. Note: Both audio and video clips may be part of a digitized information package, e.g., on a Web page. 3. To limit to a predetermined level (e.g., at the output of an otherwise linear amplifier) the amplitude of an otherwise linear signal. Note: In contrast with an analog compression circuit, which reduces the dynamic range of a signal but retains its basic waveform, a clipping circuit treats (processes, amplifies) a signal in a linear fashion unless the output level reaches a certain threshold, which it may not exceed, and at which it remains unless the input decreases to a level at which the processed output level is lower than the clipping level.

1. In e-mail, a periodic mailing of a collection of messages compiled from a mailing list or interest group. 2. A command issued to a list server or to a list processor requesting that postings be delivered to a subscriber in summary form.

1. In international direct telephone dialing, a code that consists of 1-, 2-, or 3-digit numbers in which the first digit designates the region and succeeding digits, if any, designate the country (click here for a list. ) 2. In international record carrier transmissions, a code consisting of 2- or 3-letter abbreviations of the country names, or 2- or 3-digit numbers that represent the country names, that follow the geographical place names. 3. In a URL or e-mail address, the two-letter abbreviation (subdomain suffix) used in lieu of ". Net," ". Org," or "gov. " to signify the country in which the web site originates. Note: Examples of country codes are ". Gb" for Great Britain, ". Jp" for Japan, and ". Us" for United States.

1. In interfacility cabling, a conduit, which may be direct-earth buried or encased in concrete, used to enclose communications or power cables. Note: For maximum resistance to rodent attack, direct-earth-buried conduit should have an outside diameter equal to or greater than 6 cm (2. 25 in. ) 2. See atmospheric duct.

1. In information assurance, comparing an activity, a process, or a product with the corresponding requirements or specifications. Note: Examples of verification are comparing a specification with a security policy model or comparing object code with source code. 2. The process of comparing two levels of an information system (IS) specification for proper correspondence (e.g., security policy model with top-level specification, top-level specification with source code, or source code with object code. ) 3. The checking of conformance between two representations of a system or part of a system. 4. The process of comparing two levels of system specification for proper correspondence (e.g., security policy model with top-level specification, TLS with source code, or source code with object code. )This process may or may not be automated.

1. In image processing, a sub-region of an image that is perceived as a single entity. Note: An image can contain more than one object. 2. In facsimile systems, the image, the likeness of which is to be transmitted. 3. A Passive entity containing or receiving information. Access to an object implies access to the information it contains. 4. A passive entity within a system that contains or receives information. Examples: records, blocks, pages, segments, files, etc. Note: Access to an object implies potential access to the information it contains. An entity (e.g. A program) may be both a subject and an object. Which it is depends on consideration of the type of access in which it participates. The range of valid objects is restricted by the available types of operations that can be performed, e.g. Read, write, execute, etc. See also: Subject. 5. Abbreviation of security object. 6. A passive entity that contains or receives information. 7. A passive entity that contains or receives information. Access to an object potentially implies access to the information that it contains. Examples of items that may be considered objects are: records, blocks, pages, segments, files, directories, directory trees, and programs, as well as bits, bytes, words, fields, processors, video displays, keyboards, clocks, printers, network nodes, etc. 8.

1. In general, a device that both modulates and demodulates signals. 2. In computer communications, a device used for converting digital signals into, and recovering them from, quasi-analog signals suitable for transmission over analog communications channels. Note: Many additional functions may be added to a modem to provide for customer service and control features. Synonym signal conversion equipment. 3. In FDM carrier systems, a device that converts the voice band to, and recovers it from, the first level of frequency translation.
