2 cards from this section. Quick, good the night before a test.
What is fixed allocation?
Think about equal distribution.
Define page fault.
Consider what happens when memory runs out.
What is the main disadvantage of fixed allocation?
Think about the needs of processes.
True or False: Proportional allocation assigns the same number of frames to all processes.
Consider how allocation could work based on needs.
Explain how you would apply proportional allocation to a dynamically changing set of processes, incorporating priorities. What steps would you take to assess memory needs?
Consider using a formula to assess and adjust allocations.
A system has 200 frames. Process A needs 70 frames, Process B needs 50 frames, and Process C needs 80 frames. Describe how you would handle allocation if a new high-priority Process D requiring 60 frames starts.
Think about how to balance needs without compromising performance drastically.
