The biggest difference between a community college and a university is that most community college degrees are completed in two years, while four-year university degrees are completed in four years. A bachelor's degree is not offered by most community colleges.
A community college is usually smaller, campus wise, than a university. A community college doesn't typically offer a bachelor's degree, which is a 4 year program. University's usually consist of undergraduate and graduate programs. Community colleges usually only offer associate's degrees, which are 2 year programs.
