In Distance learning, the classes are usually recorded or only materials are provided and the student studies from those materials and at the end gives the examination. But in case of online learning, you will get online classes and interaction sessions with your professors as well as you will get a more structured form of learning the course.

As a result, the senses are the same but in Online program you will get a more organized curriculum. Also in some cases the online degree are more recognized compared to that of distance learning programs.

I hope this answer helps. All the very best for your future endeavors!
