Mooduli

Mooduli is a term used in Estonian language to refer to a module or component within a larger system. In technical writing, mooduli denotes a self-contained unit that exposes a defined interface and can be integrated with other units to form a complete solution. The form mooduli is the genitive singular of moodul, the common noun for "module." The concept is central to modular design, where complex systems are decomposed into interoperable modules.

In computing, moodul-based design is used for software architecture, hardware engineering, and educational curricula. Software moodulid (plural) can be developed, tested, and deployed independently, enabling reuse and separation of concerns. In hardware contexts, moodul components may be plugged into a chassis or motherboard. In education, moodul-based curricula organize content into modules that cover a set of learning objectives.

Etymology: moodul is a loanword reflecting the same concept as English "module" and related terms in several European languages; mooduli is the grammatical form used when referencing it in Estonian phrases like mooduli arhitektuur (module architecture) or mooduli sõltuvused (module dependencies).
