What are some real-world applications of LRU caching?

LRU caching is widely used in databases, web browsers, and operating systems to manage memory efficiently.

Can you give me an example of how it's used in web browsers?

Sure! Web browsers use LRU caching to store recently accessed web pages, allowing for faster retrieval when users revisit them.

How does LRU compare to other caching algorithms?

LRU is often more efficient than FIFO or random caching because it prioritizes frequently accessed items, reducing cache misses.

Are there any downsides to using LRU caching?

Yes, LRU can be resource-intensive, as it requires tracking the order of access, which can slow down performance in some cases.
