试题2
In the field of software architecture, modularity is a cornerstone principle that emphasizes the division of a system into （1） components, each with a specific purpose and well-defined interfaces for communication. This approach facilitates the understanding, development, and maintenance of complex software systems. By promoting the reuse of （2） components, modularity also contributes to increased efficiency and reduced costs.
One of the key advantages of modularity is that it enhances （3） by allowing developers to work on individual modules in parallel, without affecting other parts of the system. This parallelism leads to faster development cycles and quicker time-to-market. Additionally, modular systems are easier to test, as each module can be tested independently, reducing the risk of errors propagating across the entire system.
Another crucial aspect of modularity is its ability to support （4） . As requirements change or new features are added, modular systems can be adapted more easily by modifying or replacing individual modules without disrupting the overall system. This flexibility ensures that software systems remain relevant and effective over time.
In practice, achieving modularity requires careful design decisions, including the identification of appropriate module boundaries and the definition of clear interfaces between modules. This involves a trade-off between （5） the system into too many small modules, which can lead to excessive complexity and communication overhead, and having too few large modules, which can hinder reusability and flexibility.
