Question 1.
Define the term 'Working Set Window'.
Show hintHide hint
Consider it as a snapshot of recent memory references.
Question 2.
What is 'Thrashing' in memory management?
Show hintHide hint
Think of it as a performance bottleneck due to poor memory allocation.
3Question 3.
What is the working set window?
- The number of total frames in memory
- A defined number of references from the past
- The number of processes running simultaneously
Show hintHide hint
Think about what recent references indicate for memory usage.
4Question 4.
True or False: Thrashing occurs when a process has more pages in memory than needed.
- True
- False
Show hintHide hint
Consider how page allocation relates to thrashing.
Question 5.
Evaluate the impact of increasing the number of processes while keeping the total frame count the same. What happens to system performance?
Show hintHide hint
Consider implications for CPU efficiency.
Question 6.
Design a simulation approach to monitor page-fault frequency and determine appropriate frame allocation for several concurrent processes.
Show hintHide hint
Think about a feedback loop for adjustments.
