Data which unambiguously distinguishes an entity in the authentication process. This [Recommendation | Part of this International Standard] requires that such an identifier be unambiguous at least within a security domain [10181-2].

1. In a system or device, any departure of the output signal waveform from that which should result from the input signal waveform's being operated on by the system's specified, i.e., ideal, transfer function.
Note: Distortion may result from many mechanisms. Examples include nonlinearities in the transfer function of an active device, such as a vacuum tube, transistor, or operational… (Read More →)

The condition prevailing when distortion of a received signal, rather than its attenuated amplitude (or power), limits performance under stated operational conditions and limits.
Note: Distortion-limited operation is reached when the system distorts the shape of the waveform beyond specified limits. For linear systems, distortion-limited operation is equivalent to bandwidth-limited operation.

A set of information processing resources distributed over one or more open systems which provides a well defined set of functionality to (human) users, to assist a given (office) task [ECMATR46].

See DCE.

Control of a network from multiple points.
Note: Each point controls a portion of the network, using local information or information transmitted over the network from distant points.

1. A database that is not entirely stored at a single physical location, but rather is dispersed over a network of interconnected computers.
2. A database that is under the control of a central database management system in which storage devices are not all attached to a common processor.

A frame-alignment signal in which the signal elements occupy digit positions that are not consecutive.

A network structure in which the network resources, such as switching equipment and processors, are distributed throughout the geographical area being served.
Note: Network control may be centralized or distributed.

Data processing in which an integrated set of functions is performed within multiple, physically separated devices.
