modulgrenser

Modulgrenser, a Norwegian term literally meaning module boundaries or module limits, is used to describe the boundary that separates or limits a module from others. The usage varies by field, and there is no single canonical definition.

In mathematics, modules are algebraic structures that generalize vector spaces. Modulgrenser is not a standard technical term in Norwegian mathematical literature. If used, it may refer loosely to internal boundaries within a module, such as chains of submodules or quotients that delineate how a module can be decomposed. In this sense, more common terms include submodule, quotient, radical, socle, and filtrations.

In software engineering and systems design, modulgrenser more often denotes the boundary around a software module: its interface, contract, and dependencies, which govern how it interacts with other modules. A well-designed modulgrenser supports explicit interfaces, low coupling, high cohesion, and clear versioning.

In other contexts such as product design, architecture, or education, modulgrenser can describe how a system is partitioned into modules with defined responsibilities and interfaces. The exact interpretation depends on the discipline and the particular framework used.
