Question 7
Explain the concept of "Cohesion" in software design.
It refers to the level of coupling between software modules.
It measures the degree to which the elements within a module belong together.
It describes the interaction between different software components.
It assesses the software's ability to adapt to changing requirements.
Question 8
What is the difference between functional and non-functional requirements in software engineering?
Functional requirements define system behavior, while non-functional requirements specify system qualities.
Functional requirements specify system qualities, while non-functional requirements define system behavior.
Both refer to the same aspect of system requirements.
Non-functional requirements are only applicable in hardware design.
