Push your limits with advanced challenges
Imagine a scenario where a computer system has limited RAM. Given the access pattern for pages A, B, C, A, B, D, A, C, can you simulate the state of the memory frame using LRU after each page is accessed?
💡 Hint: Track the history of page accesses carefully to see how replacements occur.
Discuss a situation in which implementing a hardware clock for timestamps could lead to inefficiencies in LRU. What would be a potential improvement?
💡 Hint: Think about how too much detail can lead to delays when speed is crucial.
