Computer and server cache allows the system to set resources to the side so they can prepare them more quickly the next time.
Imagine you have a toy box with lots of toys inside. Whenever you want to play with a specific toy, you have to search through the entire toy box to find it. This can take a lot of time and effort.
But if you had a small box next to you that had only your favorite toys in it, you wouldn’t have to search through the entire toy box every time you wanted to play. You could quickly and easily find your favorite toys in the smaller box.
In a computer, a cache works like this small box of favorite toys. It’s a special place where the computer stores things it thinks you might need to use again soon. When you ask the computer for something, instead of searching through all of the computer’s storage to find it, the computer looks in the cache first. If it finds what you’re looking for there, it can give it to you much faster than if it had to look through everything else.
So, a cache helps the computer work faster by keeping important things closer to it, just like how keeping your favorite toys in a small box makes it easier and faster to find them.
