In the book by enderton, A mathematical introduction to logic. Phases or terms that involves, "infinite models" and "finite models" appears, especially in section 2.6.
"Some sentences have only infinite models, like the sentence saying $<$ is an ordering with no largest element"
"It is also possible to have sentences having only finite models........"
So I'm not exactly sure what is the meaning of "finite/infinite models", hence I am if someone could explain to me, preferably with examples to illustrate.
Thank you in advance .
