What are some other cache algorithms besides LRU?

There are several cache algorithms besides Least Recently Used (LRU), such as First In First Out (FIFO), Least Frequently Used (LFU), and Random Replacement. Would you like to know more about any specific one?

Can you explain how LFU works?

Least Frequently Used (LFU) keeps track of how often items are accessed. The least frequently accessed items are removed first when the cache is full.

What about FIFO? How does that differ from LRU?

FIFO, or First In First Out, evicts the oldest item in the cache regardless of how often it has been accessed, unlike LRU which evicts the least recently used item.

Are there any scenarios where FIFO is preferred over LRU?

Yes, FIFO can be simpler to implement and may perform better in scenarios where access patterns are predictable and older items are less likely to be reused.
