What are some real-world examples of LRU caching?

Can you explain what LRU caching is and provide some real-world examples?

LRU stands for Least Recently Used. It's a caching algorithm that removes the least recently accessed items when the cache reaches its limit. Real-world examples include web browsers, database management systems, and operating systems.

How does LRU caching work in web browsers?

In web browsers, LRU caching stores recently accessed web pages and resources. When the cache is full, the browser removes the least recently viewed pages to make space for new ones, improving load times.

Can you give an example of LRU caching in a database?

Sure! In databases, LRU caching is used to keep frequently accessed data in memory. For instance, a database might cache the results of recent queries, evicting the least recently used results when new queries are executed.

What are the advantages of using LRU caching?

The advantages include improved performance, reduced latency, and efficient memory usage, as it prioritizes keeping frequently accessed data readily available.
