Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
