Question

Quizplus · Accepted Answer

When there is excessive page swapping between main memory and secondary storage, the system can become so busy swapping pages that it doesn't have much time to do useful work. This phenomenon is called thrashing. Excessive demand paging (A) can lead to thrashing, but by itself is not necessarily inefficient. Hot swapping (B) refers to the insertion or removal of a device while the system is running, and is not directly related to page swapping. Overswapping (D) is not a commonly used term in computer science, and is not directly related to the phenomenon described in the question.
