Adding to all that, LACs focus on teaching undergraduate students. Professors may do research, but they are primarily there to teach. There aren’t (usually) any graduate programs offered. They tend to be smaller than universities. Classes tend to be smaller as well.
Most LACs offer majors in at least math, the sciences, the social sciences, English, foreign languages, sometimes the arts.
LACs tend to be private though there are a few public ones, universities are both private and public.
There are exceptions.
