Oxford Basic American Dictionary

Universities and colleges both offer courses for students who are studying for their first degree (a bachelor's degree ).

Universities also offer courses for people who are studying for more advanced degrees, for example a master's degree or a Ph.D.

College is often the word we use in general conversation when we are talking about a place of higher education, even when the place we are talking about is a university: a college student ♦ "Where did you go to college?" "Ohio State University."
