Question 1

Which memory management technique automatically reclaims memory that is no longer referenced by any active part of a program?

Accepted Answer

Garbage collection

Answer

Garbage collection automatically identifies and frees memory occupied by objects that are no longer reachable, preventing memory leaks.

Question 2

In software requirement engineering, a use case diagram primarily illustrates:

Accepted Answer

Interactions between actors and the system's functional requirements

Answer

Use case diagrams show the functional requirements of a system by depicting which actors interact with which use cases, giving a high-level behavioral view.

Question 3

Which sorting algorithm has the best worst-case time complexity of O(n log n)?

Accepted Answer

Merge Sort

Answer

Merge Sort guarantees O(n log n) performance in all cases—best, average, and worst—by dividing the array in half recursively and merging sorted halves.

Question 4

Which cloud computing service model provides virtualized computing infrastructure (servers, storage, networking) over the internet?

Accepted Answer

Infrastructure as a Service (IaaS)

Answer

IaaS delivers raw virtualized hardware resources—compute, storage, and networking—that users manage and configure themselves.

Question 5

In software project management, the critical path of a project network is defined as:

Accepted Answer

The longest path from start to finish that determines the minimum project duration

Answer

The critical path is the longest sequence of dependent tasks, and any delay on this path directly delays the entire project completion.
