Question 1.
What is a hashed page table?
Show hintHide hint
Think about how standard page tables can be inefficient.
Question 2.
What does a hash function do in the context of hashed page tables?
Show hintHide hint
Consider how hashing works in general.
3Question 3.
What is the primary advantage of using hashed page tables?
- A. Increased page table size
- B. Efficient memory usage
- C. Slower access times
Show hintHide hint
Think about how memory consumption is managed.
4Question 4.
True or False: In a hashed page table, linked lists are used to handle cases where multiple virtual page numbers hash to the same index.
- True
- False
Show hintHide hint
Recall how we handle collisions.
Question 5.
Suppose a hashing algorithm for hashed page tables produces 5 entries for virtual page numbers ranging from 0 to 10. Design a table showing how collisions are handled.
Show hintHide hint
Sketch out how you'd organize the pages numerically and visualize hash hits.
Question 6.
Critically analyze the performance of hashed page tables versus conventional single-level page tables in systems with 64-bit architecture. What metrics would you consider?
Show hintHide hint
Think of operational ease and efficiency as defined in both types.
