Software Engineering MCQs

1. What is modularity in software design?

a) Writing all code in a single file b) Using only one programming language c) Dividing software into independent, interchangeable components d) Avoiding the use of functions

2. Which of the following is a benefit of modularity?

a) Increased complexity b) Higher coupling c) Easier maintenance and debugging d) Reduced reusability

3. What does high cohesion in a module imply?

a) The module depends on many other modules b) The module focuses on a single, well-defined task c) The module is tightly coupled d) The module performs multiple unrelated tasks

4. Which of the following is an example of low cohesion?

a) A module that handles only user authentication b) A module that is independent of other modules c) A module that performs a single mathematical calculation d) A module that handles user authentication, logging, and file storage

5. What is coupling in software design?

a) The process of dividing software into modules b) The degree of interdependence between modules c) The degree to which a module focuses on a single task d) The process of optimizing code for performance

6. Which type of coupling is considered the best in software design?

a) Content coupling b) Common coupling c) Loose coupling d) Tight coupling

7. What is the main disadvantage of tight coupling?

a) Improved flexibility b) Increased modularity c) Reduced maintainability d) Easier debugging

8. What is layering in software design?

a) Combining all functionalities into a single layer b) Avoiding the use of modules c) Dividing software into horizontal layers with specific responsibilities d) Increasing coupling between modules

9. Which of the following is a common layer in a layered architecture?

a) Randomization Layer b) Dependency Layer c) User Interface Layer d) Overlapping Layer

10. What is the primary advantage of a layered architecture?

a) Increased complexity b) Tight coupling between layers c) Improved separation of concerns d) Reduced modularity

11. Which of the following is a disadvantage of layering?

a) Improved maintainability b) Increased cohesion c) Potential performance overhead d) Reduced complexity

12. What is the relationship between modularity and coupling?

a) High modularity leads to high coupling b) Modularity and coupling are unrelated c) High modularity leads to low coupling d) Low modularity leads to low coupling

13. Which of the following is an example of loose coupling?

a) Modules sharing global variables b) Modules directly accessing each other's internal data c) Modules depending on each other's implementation details d) Modules communicating through well-defined interfaces

14. What is the primary goal of achieving high cohesion and low coupling?

a) To make the system harder to maintain b) To increase dependencies between modules c) To improve readability, maintainability, and scalability d) To reduce the need for testing

15. Which of the following is true about layering and modularity?

a) Layering reduces modularity b) Layering increases coupling c) Layering enhances modularity by separating concerns d) Layering is unrelated to modularity
