What are Models of Set Theory?

We are already coming up to the third installment of the new what is....? seminar. This time David Schrittesser will explain what models of set theory are. Most mathematicians phrase their thoughts in terms of sets. Thus it is probably a good idea to understand models of the theory of sets, right?
