What word best describes a coordinated set of components designed to achieve a goal?

• A. Module
• B. Network
• C. System
• D. Subassembly

Answer: (C)

A system is a coordinated set of components designed to achieve a goal. The idea is that the parts interact and align toward a shared objective, so the whole functions as more than the sum of its parts. In biology and engineering, systems have defined boundaries, inputs, processes, and outputs, and their arrangement enables the intended behavior. For example, the circulatory system moves blood to distribute oxygen and nutrients, while a computer system processes data from input to output through interconnected hardware and software.

A module is a self-contained unit that can be part of a larger system, performing a specific function but not by itself describing the complete coordinated ensemble. A network emphasizes connections and communication among elements rather than a single goal-oriented whole. A subassembly is a subset of parts assembled into a piece of a larger product, not the full set designed to achieve a particular outcome.

So the best word is system.
