Question 1.
What is virtual memory?
Show hintHide hint
Think about how your computer uses hard drive space when memory is full.
Question 2.
Define a page fault.
Show hintHide hint
Consider what happens when a program tries to access something that's not in the hard drive.
3Question 3.
What is the primary function of virtual memory?
- A. To increase the speed of the CPU
- B. To manage and extend memory beyond physical limits
- C. To provide secure data access
- D. To improve power efficiency
Show hintHide hint
Remember its role in managing memory.
4Question 4.
True or False: Page faults increase the performance of a system.
- True
- False
Show hintHide hint
Think about what happens during a page fault.
Question 5.
Suppose you have a system with limited physical memory, and a process has a working set that requires more memory than what’s available. Design a strategy outlining the steps to alleviate the thrashing phenomenon.
Show hintHide hint
Think practically about managing both memory allocations and the priorities of processes.
Question 6.
A computer program utilizes a page replacement algorithm that often leads to high page fault rates. Analyze why this may happen and propose alternative algorithms that could improve overall efficiency.
Show hintHide hint
Consider how frequently accessed pages correlate with efficiency.
