What is "rollback" netcode, and what are the other types of netcode?

I couldn’t find a definition on Google.

You have to type something in the rectangle to make it work.

Google doesn’t give the same search results for everyone.

I typed rollback netcode into google and got two links which gave answers already…

Of course the second link is a thread I made a while ago lol
