Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a system with 128 total frames and three processes needing 15, 25, and 50 frames, respectively. Calculate the number of frames allocated to each process based on proportional allocation principles.

💡 Hint: Be careful with rounding off to the nearest integer.

Challenge 2 Hard

In a scenario where high-priority processes frequently swap with low-priority processes, analyze how this impacts the performance of critical applications in the system.

💡 Hint: Consider both immediate and long-term impacts on system performance.
