💡 Model Answer
Caching is a temporary, in‑memory storage mechanism used to speed up access to frequently used data. Cached data is volatile and may be evicted when memory pressure occurs or when the cache is refreshed. Persistence, on the other hand, refers to writing data to durable storage such as a database, file system, or disk. Persisted data survives application restarts and failures. In practice, caching is used for performance optimization, while persistence ensures durability and consistency.
