What are cache replacement policies?

Cache replacement policies are algorithms that determine which items to remove from a cache when it becomes full.

Can you explain some common cache replacement policies?

Sure! Common policies include LRU (Least Recently Used), FIFO (First In, First Out), and LFU (Least Frequently Used).

How does LRU work in practice?

LRU keeps track of the order in which items are accessed and removes the least recently used item when space is needed.

What are the advantages of using LFU over LRU?

LFU can be more efficient for workloads with stable access patterns, as it prioritizes frequently accessed items.
