Question 1

What is the primary advantage of using hashed page tables?

  • A. Increased page table size
  • B. Efficient memory usage
  • C. Slower access times

💡 Hint: Think about how memory consumption is managed.

Question 2

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

💡 Hint: Recall how we handle collisions.

Challenge Problems

Push your limits with challenges.

Question 1

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.

💡 Hint: Sketch out how you'd organize the pages numerically and visualize hash hits.

Question 2

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?

💡 Hint: Think of operational ease and efficiency as defined in both types.
