📊 Explaining Caching (Big Bang Theory Edition)
Caching is like your brain keeping frequently used information handy so you don’t have to go look it up every single time.
Instead of fetching data from the slow main source (database, API, hard drive) again and again, you store a temporary copy in a fast-access place (memory, Redis, CDN). Next time someone asks, boom, instant delivery.
It’s the reason websites load fast, apps feel snappy, and your Netflix doesn’t buffer every 5 seconds.
