Diploma

I will list down some top colleges as per popular opinion:
College of Engineering, Defence Institute of Advanced Technology, Army Institute of Technology, Bharati Vidyapeeth Deemed University, MIT World Peace University, Vishwakarma Institute of Information Technology, etc. (Not listed as per priority, all of them are great). But, if geographical location is not a concern then I had definitely suggest Chandigarh University as one of the best Computer Engineering college. It has great faculty and academic record, astonishing placements and a diverse peer group which helps enhance individual personality. I had recommend to checkout more about the same on it is official website. All the very best.

I have done my graduation from kalaniketan college Jabalpur Engineering College, there are plenty of reasons why this college is great!
Great Alumni Network, In all the government sector you will find people from JEC, 90% chances that your interview will be taken be JECian(people from IIT go to Silicon Valley and People from JEC goes to Government Job)
Infrastructure is old, but great.
All the facilities are available, but you need to be serious to use them.
Sport Facilities are great, you need to have good contact with Sport Department to access all the sport equipment.
Hostel are not in great condition, but still worth living. I have never seen hosteler complaining about hostels, Mess food is Great.
Hostel Ground are maintained by student it-self, every year they arrange sport fest among hostel. They even skip Mid-semester for such games.
