Which term refers to a cohesive set of parts designed to achieve a particular result?

• A. System
• B. Item
• C. Module
• D. Unit

Answer: (A)

A system is a cohesive set of parts designed to work together to achieve a particular result. This emphasizes integration and interdependence among components, producing a coordinated function—such as the circulatory system where heart, vessels, and blood collaborate to circulate blood and maintain tissue perfusion. A module is usually a self-contained part of a larger system and can be developed or replaced independently, not the entire cohesive whole. A unit refers to a single element or component rather than the integrated assembly. An item is simply an object or entry, not a structured collection designed for a specific outcome.
