Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a simulation that models how thrashing occurs and its effects on CPU utilization under varying degrees of multiprogramming.

💡 Hint: Think about how each process's memory needs change based on the total number of processes.

Challenge 2 Hard

Propose a strategy to dynamically adjust memory allocation to processes based on real-time page fault statistics.

💡 Hint: How would you prioritize which processes need more frames?
