What are some common cache algorithms?

What are some common cache algorithms used in computing?

Some common cache algorithms include Least Recently Used (LRU), First In First Out (FIFO), and Least Frequently Used (LFU).

Can you explain how the LRU algorithm works?

Sure! LRU keeps track of the order in which items are accessed and removes the least recently used item when the cache is full.

What are the advantages of using the FIFO algorithm?

FIFO is simple to implement and works well when the access pattern is predictable, but it may not always be efficient.

Are there any scenarios where LFU is preferred over LRU?

Yes, LFU is preferred in scenarios where certain items are accessed much more frequently than others, as it prioritizes those.
