4 cards from this section. Quick, good the night before a test.
What is a page-fault?
Think about what happens when a program requests data that isn't immediately accessible.
Define thrashing.
Consider the consequences of insufficient memory allocation.
What is thrashing?
Think about what happens when memory is insufficient.
True or False: Fixed allocation guarantees optimal performance for all processes.
Consider if all processes truly have the same needs.
Consider a system with 100 frames and 4 processes: Process A requires 40 frames, Process B requires 30 frames, Process C requires 20 frames, and Process D requires 10 frames. What could be an effective allocation strategy?
Think about how you would divide the 100 frames assigned based on the needs of each process.
If increasing the number of processes in the system led to thrashing, what systematic changes could be made to improve performance?
Consider if there are overload conditions that cause frame distribution issues and how you can solve them.
