Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does Belady’s anomaly demonstrate?
- A situation where increasing frames always reduces faults
- A situation where increasing frames can sometimes increase faults
- A situation unrelated to memory management
💡 Hint: Recall how page relationships affect fault occurrences.
Question 2
Is the Optimal Algorithm effective in preventing Belady's anomaly?
- True
- False
💡 Hint: Focus on the definition of the Optimal Algorithm.

Challenge Problems
Push your limits with challenges.
Question 1
Given a sequence of page references (7, 0, 1, 2, 0, 3, 0, 4) and three memory frames, how many page faults occur under the Optimal Algorithm?
💡 Hint: Consider how you choose which pages to evict.
Question 2
If a system uses LRU with the following reference string and memory frames (1, 2, 3, 1, 4, 1, 2, 5), calculate the number of page faults.
💡 Hint: Track the pages that remain in memory based on their usage.
