Questions and Answers

What is the benefit of an individual software engineer specializing in a component?

  • It makes the component harder to understand.
  • The individual can work faster on multiple components.
  • The component becomes less reusable.
  • The component becomes easier to understand. (correct)

    • What does high cohesion in a module indicate?

  • The module contains elements that are functionally unrelated.
  • The module contains elements that are not related to each other.
  • The module has a low degree of functionality.
  • The module keeps together elements that are related to each other. (correct)

    • What does reducing coupling between modules help in achieving?

  • It makes changes in one module require changes in other modules frequently.
  • It helps in minimizing interdependencies between modules. (correct)
  • It makes the system harder to understand.
