Memcached

Memcached is an open-source system that helps websites and applications load faster by temporarily storing frequently accessed data in a fast, in-memory cache. When a user requests information, Memcached quickly retrieves it from this cache instead of repeatedly fetching it from slower, persistent storage like a database. This reduces delays and improves performance, especially under high traffic. Think of it as a quick-access temporary storage that holds commonly used data, enabling applications to serve responses more efficiently and handle more users smoothly.
