Let's say we're in a computer room of an university. In order to use a computer, you have to write your name, department, and seat number in a notepad.
What do you call that notepad? Or what adjective should you use to describe it?

It's a log book or simply, log.
In corporate buildings, I always see log books near the security area/concierge so they can record the names of the visitors who come in and out of the building, and the time they went in and out as well, for security purposes.
This may be used in other similar situations where tracking of activities is important. i.e., in your question, the usage of computers in a university computer room.
