Hii there, your questions seems quite confusing, but still I want to to make you know about NIT Nagaland, it is established in 2010. College is same for both branches, so there is not much difference, but yes its about your interest, whether you want to opt for ECE or E&IE barnch. Both are having done differences. Like E&IE deals with logic design of instruments required in industries and process control while ece is about communication. Both tend to have inclination to some cse subjects.

Hope you got your answer. Good luck!!
