colleges are generally referred to community 2-year higher education institutions after high school. There are 4-year colleges too, but they are limited to certain fields of interest. University level is the highest level with higher advances in degrees and subject matter.
Basically, you would go to a junior college for about two years--get your transfer credit put in and then transfer to a 4-year university where you would end up getting a Bachelors, Masters, or even a PHD if you wish.
