Show hintHide hint
Think about how a process uses memory.
Question 2.
What is a page fault?
Show hintHide hint
Relate it to the necessity of accessing pages.
3Question 3.
What is thrashing?
- A situation where CPU utilization is high.
- A condition where a process frequently swaps pages.
- A model for allocating frames.
- An event that occurs during I/O operations.
Show hintHide hint
Think of the impact on performance.
4Question 4.
True or False: Thrashing occurs when a system has enough frames for all processes.
- True
- False
Show hintHide hint
Consider memory allocation.
Question 5.
Design a simulation that models how thrashing occurs and its effects on CPU utilization under varying degrees of multiprogramming.
Show hintHide hint
Think about how each process's memory needs change based on the total number of processes.
Question 6.
Propose a strategy to dynamically adjust memory allocation to processes based on real-time page fault statistics.
Show hintHide hint
How would you prioritize which processes need more frames?
