Why does Chanda use a tablet?

When Chanda gets uploaded and is stuck in a loop working for Prasad I notice he is using a tablet. It has been a little while since I watched the show but what work is Chanda exactly doing? What would he need a tablet for?

I am in the CS field and I use my tablet for creating assets, but I don't understand the work he does for him to use a tablet.

Probably a stupid question and I looked over something but I was just curious.
