What does modular design in software development entail?

• A. Combining all system components into one large module
• B. Breaking a system into smaller, manageable units
• C. Using a single programming language for development
• D. Maximizing system complexity for advanced users

Answer: (B)

Modular design in software development involves breaking a system into smaller, manageable units or modules. This approach allows developers to create distinct components that encapsulate specific functionalities. Each module can be developed, tested, and maintained independently, which enhances the overall efficiency of the development process. By organizing code into modules, teams can collaborate more effectively, as different developers can work on different modules simultaneously without causing conflicts. Additionally, modular design promotes reusability, as modules can be used across different projects without the need for complete rewrites. It also simplifies debugging and maintenance, as isolating issues becomes easier when the code is well-structured into discrete components. This strategy contrasts with combining all system components into one large module, which would lead to a monolithic structure, making the codebase harder to maintain and understand. Using a single programming language does not inherently define modularity, nor does maximizing complexity enhance usability. The key benefit of modular design is its ability to create a more organized and manageable code structure.
