One of the most important innovations of demand paging is that it makes ____ feasible.
A) parallel memory
B) automatic allocation
C) spontaneous allocation
D) virtual memory

Question

Quizplus · Accepted Answer

Demand paging is a memory management technique that allows a process to be executed even when it is not completely in main memory. It is an extension of virtual memory that uses paging hardware to fetch only the pages of code and data that are needed at any given time. This makes virtual memory feasible, allowing more programs to be run simultaneously than would be possible with physical memory alone. Therefore, D (virtual memory) is the best choice for this question.
