What are caching layers?

Caching layers are like extra memory that helps things work faster, think of it as a helper who remembers what you asked for before.

Imagine you're at a candy store every day. The first time, the shopkeeper has to go behind the counter to get your favorite candy. But after a while, the shopkeeper starts remembering which candy you like and keeps it on the front shelf just for you. Next time you come in, they can give it to you right away, no need to go all the way back.

That’s how caching layers work! They store information so that when you ask for something again, it's already ready. This helps computers and websites run quicker because they don’t have to search for everything from scratch each time.

Sometimes there are multiple helpers, like a team of shopkeepers. One might remember your favorite candy, while another remembers how much you usually buy. Together, they make things even faster. That’s like having multiple caching layers, each helping in its own way to speed things up.
