Question 1

What does the Clock Algorithm primarily utilize for managing page replacement?

  • Reference Bits
  • Physical Memory Size
  • CPU Speed

💡 Hint: Consider what the algorithm tracks to make decisions.

Question 2

True or False: In the Clock Algorithm, a page with a reference bit of 1 will be immediately replaced.

  • True
  • False

💡 Hint: Think about the concept of 'second chances' in the algorithm.

Challenge Problems

Push your limits with challenges.

Question 1

Given a sequence of page requests and ten frames managed by the Clock Algorithm, calculate the number of page faults that occur. Assume frames are initially empty and list each step.

💡 Hint: Track how each request interacts with reference bits.

Question 2

How would the modified clock algorithm behave significantly differently from the Clock Algorithm in a scenario involving a high number of dirty pages?

💡 Hint: Consider which pages are favored for replacement when faced with mixed types.
