At the university I am going to they require a book for every course, and a plan on how they're going to use it.
What's great is that I've all my professors right back. All of my professors include a book that is fairly old and include some verbage in the syllabus about how they "reserve the right to assign reading assignments" i.e. book quizzes, but they actually never have assigned them previously and don't even have material made up.
I'm guessing the reason for this policy is because the university has an opt-out (you have to re-opt out every semester, and you have to check some professors lock their own material) $150 paywall to get online access to your books. The only way I can see this as worth it is if your taking like 6 classes and all of them use books written in the last 5 years or so...
How does DRM(Digital Rights Management) that has as function the blocking of copying or "blocking non legitimate access" of copyrighted media prevent cheating?
Because that is far different as things like access to tests answers, because that is not the same than copyright.
It's a web page. Webpages have shit to do with the operation system. Webpages however have been a classic Microsoft truck to force people on their shit software (hello ie6 hell!) so you can pretty much bet money on it that this is done at the request of a manager who got a good deal with Microsoft.
