Generally, a university is larger than a college and offers advanced degrees (Masters, Doctorates, Professional degrees in medicine and law) in addition to undergraduate degrees (Bachelors). Also universities are generally divided into colleges. For example, a university might be comprised of the College of Arts and Sciences, the College of Engineering, the College of Architecture, the College of Law, the College of Medicine, the College of Business, etc. I hope this helps!
