In terms of module architecture, what does "loosely coupled" mean?

• A. Modules are highly interdependent
• B. Modules can operate independently and are easier to modify
• C. Modules require constant communication
• D. Modules are tightly integrated and affect each other's logic

Answer: (B)

Loosely coupled architecture refers to a design principle where individual modules or components are relatively independent from one another. This means that changes made to one module are unlikely to necessitate changes in another, which enhances modularity and flexibility within the system. In a loosely coupled architecture, the interactions between modules are minimized, and each module can function autonomously, allowing for easier modifications and updates without impacting the overall system. This independence also facilitates better maintainability and scalability, as developers can work on different modules concurrently and integrate them seamlessly when needed. In contrast, the other options describe characteristics associated with tightly coupled architectures, where components are heavily interdependent, require constant communication, and often necessitate extensive changes when any part of the system is modified. This can complicate development and maintenance, highlighting the advantages of a loosely coupled approach.
