Hello aspirant. First I will make this thing clear for you. Data analytics, networking, artificial intelligence are all domains. They are not branches or courses. These domains comes under computer science or IT branch. Initially in the  course curriculum of any computer science or information technology department, these are made as subject where you can learn basics and understand. These can never be found as branches in any engineering college.

If you want to pursue these, then take the branch of computer science or IT in engineering college, then you can build your career in that path

Hope this helps

Regards
