Question 1

What is the primary purpose of the FIFO page replacement strategy?

  • To evict the most recently used page
  • To evict the oldest page
  • To randomize page replacement

💡 Hint: Think about which page would leave the queue first.

Question 2

True or False: The clock algorithm allows access to a page that is currently being modified.

  • True
  • False

💡 Hint: Consider what happens to modified data.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a system using FIFO replacement with a memory size capable of holding four pages. Given an access sequence of 1, 2, 3, 4, 2, 1, 5, 1, and 2, how many page faults will occur?

💡 Hint: Track the pages in memory and how they change with each access.

Question 2

In a sampled LRU scenario, if the reference byte for a particular page reflects [0, 0, 1, 1, 0, 1] over 6 intervals, determine the numerical value of the reference byte and its implication for page replacement.

💡 Hint: Convert the binary to decimal to assess recent usage.
