Question 1.
What is the main consequence of thrashing?
Show hintHide hint
Think about the time spent servicing page faults.
Question 2.
Define page-fault.
Show hintHide hint
It occurs when the required page is absent.
3Question 3.
What is the main cause of thrashing?
- Insufficient page frames
- Inadequate CPU speed
- Excessive process priority
Show hintHide hint
Consider how page frames interact with process requirements.
4Question 4.
True or False: Proportional allocation distributes frames equally among processes.
- True
- False
Show hintHide hint
Remember the difference in allocation strategies.
Question 5.
A system has 100 pages to allocate among 4 processes. Process A requires 20 pages, Process B requires 30, Process C requires 25, and Process D requires 15. How would proportional allocation be applied?
Show hintHide hint
Use the formula based on proportional allocation.
Question 6.
Describe how to optimize frame allocation for an application that experiences high page-fault rates. What strategies would you implement?
Show hintHide hint
Think about the balance between performance and available resources.
