What is Prefetching?

Prefetching is when your brain gets ready for something before it actually happens, like when you grab your shoes before leaving the house.

Imagine you're playing with your favorite toy. Right before you start playing, you pick up the toy and bring it close to you. That way, when the game starts, you don’t have to run all the way across the room to get it. You already have it in hand!

Prefetching works like that. It's when your computer gets ready for something before you even ask it to do anything. Like when you click on a video, and sometimes the next part of the video starts playing before you're done watching the first part.

Think about eating cereal in the morning. You might pour your cereal into a bowl before you sit down at the table. That’s like prefetching, you’re getting ready for breakfast even though it hasn’t started yet!

Your brain and your computer both do this to make things faster and smoother, just like how you don't want to wait until the last minute to get your shoes on!
