What do the yellow/red cards do in the world cup?

I know the very basics of what they do. Two yellows equal one red. And red means you’re ejected from the game.

Here is what I want to know:
If you get one yellow card, does it carry over to the next match?

Does getting a red card or two yellows keep you out of the next match?

Is there anything else that happens that I don’t know?
