Summary
Explore virtual memory management by learning about various page-replacement policies including LRU and scan-resistant algorithms like ARC. Understand how these policies optimize performance and the trade-offs involved, especially in contexts where paging costs are high. This lesson helps you grasp the evolution and practical considerations of memory management in operating systems.

We have seen the introduction of a number of page-replacement (and other) policies, which are part of the VM subsystem of all modern operating systems. Modern systems add some tweaks to straightforward LRU approximations like clock; for example, scan ...
