Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a memory allocation scheme for a hypothetical system with three processes of sizes 10, 50, and 100 frames, respectively. How would you allocate the frames among these processes using both proportional and fixed allocation methods?

💡 Hint: Consider the total size and how to distribute accordingly.

Challenge 2 Hard

A system is experiencing thrashing. Identify steps that can be taken to alleviate the issue based on memory management principles discussed.

💡 Hint: Focus on how to balance load across processes to reduce page-faults.
