Imagine you have a big jar of cookies, and your parents tell you that you can have a certain number of cookies every day. Let's say they give you a quota of five cookies per day. That means you can eat up to five cookies each day.

Now, imagine that one day, you really love cookies and you eat seven of them instead of five. Uh-oh! You went over your quota, which means you ate more cookies than you were allowed to. When this happens, your parents might ask you to pay for the extra cookies you ate.

In the same way, a quota is like a limit or a specific amount of something you are allowed to have or use. It could be cookies, or it could be something like internet data or electricity. When you go over that limit or quota, it means you've used more than you were supposed to.

The reason you might need to pay more when you go over a quota is because there are costs associated with providing extra cookies, data, or electricity. Just like how your parents may need to buy more cookies if you eat more, companies or services have to pay for the additional resources they provide when people go over their quotas.

So, when you go over a quota, you might have to pay extra because you're using more than what was initially allowed, and that extra payment helps cover the costs of providing you with the extra stuff.

I hope that makes sense! Let me know if you have any more questions.
