Question 1

What is the primary goal of proportional allocation?

  • To prioritize all processes equally
  • To allocate more frames to larger processes
  • To prevent thrashing

💡 Hint: Consider how memory should match process demands.

Question 2

True or False: Local allocation allows a process to replace frames from any other process allocated memory.

  • True
  • False

💡 Hint: Think about frame access restrictions.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
