Which of the following is not correct about the virtual memory segmentation ?

1. AIt is not necessary to load all of the segments of a process.
2. BIt has no internal fragmentation.
3. CIt has large virtual address space.
4. DIt provides lower degree of multiprogramming.

Show answer & explanation

Correct answer: D. It provides lower degree of multiprogramming.

Explanation

With virtual-memory segmentation, not all segments need be loaded, there is no internal fragmentation, and the virtual address space is large. Because processes need less real memory, it allows a higher, not lower, degree of multiprogramming.
