What is LRU?
An example of an AI chatbot conversation about the Least Recently Used caching algorithm.

LRU stands for Least Recently Used. It's a caching algorithm that removes the least recently accessed items first.

What are some use cases for LRU?
LRU is commonly used in memory management, database caching, and web caching to optimize performance.
Are there any alternatives to LRU?
Yes, alternatives include FIFO (First In, First Out), LFU (Least Frequently Used), and ARC (Adaptive Replacement Cache).
