Challenge Problems
Push your limits with advanced challenges
A system is currently supporting 5 processes with varying memory demands, each needing 10, 20, fewer than 8, 30, and 12 frames respectively. Based on proportional allocation, how would you divide a total of 80 available frames among these processes?
💡 Hint: Break down each need to determine a fair ratio.
Given a series of page accesses [A, B, C, A, D, B, C, E], demonstrate how both FIFO and LRU algorithms results in different outcomes based on a frame limit of 3.
💡 Hint: Map each function to see which pages are retained under both methods.
