What are the different types of cache policies?
There are several types of cache policies, including LRU (Least Recently Used), FIFO (First In First Out), and LFU (Least Frequently Used). Each has its own advantages depending on the use case.
Can you explain LRU in more detail?
Sure! LRU stands for Least Recently Used. It keeps track of the order in which items are accessed and removes the least recently used item when the cache reaches its limit.
What about FIFO? How does it work?
FIFO, or First In First Out, removes the oldest item in the cache first. It’s simple to implement but may not always be the most efficient.
Are there any other cache policies I should know about?
Yes, there's also LFU (Least Frequently Used), which removes items that are used least often. Additionally, there are adaptive policies that combine multiple strategies.
