Question

Quizplus · Accepted Answer

This statement is true. When an operating system is constantly paging, it is a sign that it does not have enough physical memory to meet the demands of the applications that are running. As a result, the operating system spends most of its time swapping pages between physical memory and disk, instead of actually executing application software. This is commonly referred to as thrashing.
