What’s the difference between Art Institutes, and Art Schools?

I don’t know whether i should be looking for art schools/universities/colleges, or art institutes…? What’s the difference???

The difference between a university and college, is that a college offers a 4 year degree. A university offers Masters (6 year) and Doctorate (8 year) degrees. The only Art Institute I am familiar with is the Art Institute of Chicago, and it is a museum. I would stick with a college or university in my search for education.
