VIT Vellore

SASTRA University is the best option as it has better placement opportunities.

Yes, you can get admission, but the fee structure is high.

ENTC and computer are really two different fields and you need to choose the stream based on your interest. As far as colleges are concerned, I can talk about Cummins as I know a little about VIT. Cummins is autonomous and has good opportunities for placements for people in Computer and IT streams.
All the best.
