Why Do Computers Sometimes Crash Like This?

Computers crash when they get confused or overloaded, like a kid who’s trying to do too many things at once. Imagine your computer is a robot with a brain made of puzzle pieces, if it gets stuck on one puzzle and can't move forward, it might freeze up or even shut down. Sometimes, the robot runs out of space in its backpack (which is called memory), and that makes it crash too.
