How does FIFO caching work?

Can you explain how FIFO caching works?

FIFO caching, or First-In-First-Out caching, is a method where the oldest data is removed first when the cache reaches its limit.

What are the advantages of using FIFO caching?

The main advantages include simplicity and predictability, as it always removes the oldest items, which can be effective for certain workloads.

Are there any downsides to FIFO caching?

Yes, one downside is that it may remove frequently accessed items if they were added earlier, potentially leading to cache misses.

How does FIFO compare to LRU caching?

FIFO is simpler but less efficient than LRU (Least Recently Used), which keeps frequently accessed items longer.
