http://en.wikipedia.org/wiki/College In American English the term "college" is generally reserved for institutions of higher education, which are often (furthermore) totally independent and fully empowered to grant degrees. The usual practice in America today is to call an institution made up of several faculties and granting a range of higher degrees a "university"; a smaller institution only granting bachelor's or associate's degrees is called a "college". (See liberal arts colleges, community college). Nonetheless, a few of America's most prestigious universities, such as Boston College and Dartmouth College, have retained the term "college" in their names for historical reasons though they offer a wide range of higher degrees.
Usage of the terms varies among the states, each of which operates its own institutions and licenses private ones. In 1996 for example, Georgia changed all of its four-year colleges to universities, and all of its vocational technology schools to technical colleges. (Previously, only the four research institutions were called universities.) Other states have changed names of individual colleges, many having started as a teachers' college or vocational school (such as an A&M — an agricultural and mechanical school), and ended up as a full-fledged state university.
It should be noted, too, that "University" and "College" do not exhaust all possible titles for an American institution of higher education; others include "institute", "academy", and "school" as in the Massachusetts Institute of Technology <1> (
