Effective Modular Design In Software Engineering

In the world of software engineering, modular design plays a crucial role in creating robust and maintainable systems. It involves breaking down a complex software system into smaller, self-contained modules that can be developed, tested, and maintained independently. Effective modular design brings numerous benefits, including improved code readability, reusability, testability, and ease of maintenance.
