What are the drawbacks of FIFO caching?

FIFO caching, or First-In-First-Out caching, can lead to several drawbacks. One major issue is that it may evict frequently accessed items if they were added earlier, potentially causing cache misses.

Can you explain why that happens?

Sure! FIFO doesn't consider the frequency of access. So, if a popular item was added first, it might be removed just because it was older, even if it's still needed.

Are there any scenarios where FIFO caching is beneficial?

Yes, FIFO can be beneficial in scenarios where the access pattern is predictable, and older items are less likely to be reused, such as in streaming data.

What are some alternatives to FIFO caching?

Alternatives include LRU (Least Recently Used), LFU (Least Frequently Used), and ARC (Adaptive Replacement Cache), which consider access patterns more effectively.
