Sequenzielle

Sequenzielle is a German adjective meaning sequential or in sequence. It is used to describe processes, operations, or structures that occur in a fixed order or are performed one after another, as opposed to parallel or simultaneous execution. The term is derived from the noun Sequenz (sequence) and is inflected according to gender, case, and number, for example sequenzielle Verarbeitung (sequential processing) or sequenzielle Abläufe (sequential procedures).

In computing and data processing, sequenzielle Verarbeitung refers to tasks executed in a single thread or in a defined order. It is often contrasted with parallele Verarbeitung (parallel processing). Sequential access to data means reading elements in a fixed order, in contrast to random or direct access. Some file systems and storage devices provide both modes, with sequential access sometimes optimized for streaming large files.

In statistics and experimental design, sequenzielle Methoden or sequentielle Analyse refer to procedures that assess data as it is collected, with the possibility of stopping early. The sequential probability ratio test (SPRT) is a classic example. These methods aim to control error rates while potentially reducing the required sample size.

In other domains, sequenzielle describes ordered sequences of events, steps in a workflow, or linguistic sequencing. The term is widely used across disciplines to emphasize a defined, stepwise order rather than simultaneous or random action. See also terms like sequenzielle Verarbeitung, sequenzielle Zugriff, and sequenzielle Analyse as domain-specific usages.
