What implies that modules are tightly coupled?

• A. Modules operate independently of each other
• B. Modules are designed for ease of modifications
• C. One module relies on the internal logic of another
• D. Modules can be changed without impacting others

Answer: (C)

Tightly coupled modules imply a strong interdependence between them, where one module's functionality is closely linked to the internal workings or logic of another. When one module relies on the internal logic of another, changes in the implementing module can cascade, requiring modifications in all dependent modules. This scenario often leads to challenges in maintenance, as a single change would necessitate a thorough understanding of how the modules interact, making the overall system more complex and less adaptable. Understanding that tight coupling often limits the modularity of a system helps in grasping design principles. In contrast, loosely coupled modules are designed to operate independently, allowing for flexibility and easier maintenance. This highlights the importance of aiming for modular designs that promote separation of concerns, enhancing both the robustness and longevity of software systems.
