ELI5: Explain Like I'm 5

Global precedence

Global precedence is like having a set of rules that tell you what things are more important than others. Let's say you have a bunch of toys in your room, but your mom tells you that cleaning up your Lego blocks is more important than putting away your stuffed animals. That means, according to the rule, that you should clean up your Lego blocks first before putting away your stuffed animals.

Similarly, in the world of computers, there are rules that prioritize certain things over others. For example, if your computer is doing several things at once, like playing music and running a game, there are some things that need to happen first. The music needs to keep playing without interruptions so you can enjoy listening to it, and the game needs to run smoothly so you can keep playing it.

Global precedence helps the computer figure out which thing to prioritize based on how important it is. So the computer will make sure that the music continues playing smoothly even if the game is lagging because the music is more important.

In summary, global precedence is like a set of rules for a computer to follow in order to prioritize certain tasks or actions over others, based on their importance.
