ELI5: Explain Like I'm 5

Data hazard

Alright, kiddo! So, you know how sometimes when you play with your toys, you need to use them in a certain order? Like, you need to put the car on the ramp first before you can make it go down? That's kind of like what happens in a computer when it's doing a lot of things really fast, like when it's trying to do math or show you pictures.

Now imagine that the computer needs to use some information that it hasn't gotten yet. It's like trying to make the car go down the ramp before you even put it on there! That's called a data hazard.

But don't worry, computers are very smart and they have ways to deal with data hazards. They can either stop everything and wait until they get the information they need, or they can plan ahead and try to get the information sooner so they don't have to stop. It's kind of like if you know you're going to need a certain toy later, you make sure it's already out and ready to use when you need it.

So, that's a data hazard! It's when a computer needs information that it doesn't have yet, but it can figure out ways to deal with it and keep working. Pretty cool, huh?
