2 cards from this section. Quick, good the night before a test.
What is the purpose of the Clock Algorithm?
Think about memory management.
What does a reference bit indicate?
Focus on tracking page usage.
What type of algorithm is the Clock Algorithm?
Think about what the algorithm tries to emulate.
True or False: A dirty page does not need to be written to disk before replacement.
Consider what happens when a page is modified.
You have 6 pages in memory with reference bits: A(1), B(1), C(0), D(0), E(1), F(0). If a page fault occurs for G, which page will be replaced? Illustrate the process.
Visualize the process of checking bits in a circle.
Explain how increasing the number of frames in a system could lead to more page faults under certain conditions using FIFO versus Clock Algorithm.
Consider page access patterns and how they affect fault rates.
