What is the difference between B.Tech and BE?

The only difference that matters is this: "The B.Tech course is somewhat more practically intensive than the BE course which is more theoretical" The difference (which is quite minor) between the two degrees can be understood from their names itself, Engineering vs. Technology.

There is not a much difference in both of them Both degrees have a same value. But only difference is that B.Tech degree is issued by the university which only deals with the technical studies and B.E degree is issued by a university which deals with Both Technical and Non-Technical branches.
