3 cards from this section. Quick, good the night before a test.
What is a page fault?
Think about what happens when memory access fails.
What does the valid bit indicate?
Consider what happens to the page if it's not in memory.
What happens when a page fault occurs?
Remember the main action triggered by the fault.
True or False: If a page fault occurs, the valid bit in the page table entry will be set to 0.
Consider the definition of the valid bit.
How might different page replacement algorithms impact performance during heavy memory loads?
Consider how replacement choices affect access patterns and overall loading efficiency.
The CPU encounters 10 page faults while executing 100 instructions. Determine the effective time taken if each page fault costs 50 ms and each instruction without a fault costs 1 ms.
Calculate the total execution time based on individual instruction and fault times.
