In some schools it refers to courses that are taken by undergraduates in their first and second years (the earlier/lower half of the four year degree). It happens to also be the case that you can transfer into a four year university from a community college/junior college after two years, thus bypassing lower division coursework. However this can vary a lot school to school and degree to degree because sometimes four year schools want you to complete certain coursework at their standards rather than external standards (especially if the course is directly a part of the major you’re pursuing).
