Replacement strategies

Replacement strategies are methods used to decide which data or items to remove or replace when a system reaches its limit, such as a full cache or memory. They help optimize performance by choosing the least useful or least recently used items to discard, making room for new, more relevant data. Different strategies, like Least Recently Used (LRU) or First-In-First-Out (FIFO), prioritize items based on usage patterns or age. Effective replacement strategies improve efficiency and speed in computers, ensuring that the most relevant data is always accessible.
