Questions regarding allowance of devices in hostels in DPS Vasant Kunj

I currently study in Shiksha The Gurukul (ICSE), Tinsukia Assam. I wish to crack IIT-JEE with the Computer Science Branch. Therefore, I talked to my counselor, and she advised me that I should take admission in your school. So, I will be taking coaching from Aakash Byju's Live Classes. Regarding the same, I had some queries: 1. Is a laptop allowed for hostellers? 2. if yes, then for how long, and is it extendable in special cases and requests? 3. Is a tablet allowed for hostellers, as most of the content would be present in it? 4. Is wi-fi available for the hostellers? I hope you look into the matter and solve my queries at the earliest... Also, it would be very kind of you to please provide me with the contact of the school so that we do not have any issues.
