Challenge Problems
Push your limits with challenges.
Question 1
A system uses the second chance algorithm for page replacement with pages A, B, C, D, and E. If A and C have their reference bits set, which one gets evicted when memory is full?
💡 Hint: Consider which pages have been given chances already.
Question 2
If you have a page access pattern of A, B, C, D, A, B over a series of accesses with a maximum of 3 pages in memory, how many page faults occur with FIFO and sampled LRU?
💡 Hint: Think about the differences in how pages are tracked.
