A uuid is something that can be used as an id (identifier). It stands for Univerally Unique Identifier. This has a list of all of them, because it generates every valid one.
I did learn what it stood for in my travels. I wish to know the use cases for such things. Eli5 if posssible, please.
They are used as ids, like a post id or a user id in technology.
One use is in URL identifiers. If my account number is 47, for example, I could reasonably guess that accounts 1-46 exist and potentially look at other customers' data.
But if it uses a UUID instead then it's a lot harder to do that.
