Can the school see what I'm doing on their internet?

Yes, they can. When you connect to the Internet through your school, you aren't connecting directly. Anytime you connect to the Internet, you are actually connecting to a network interface that routes you to the Internet. Your school probably logs the websites your device visits and more than likely is set up to alert someone if you visit a suspicious site.

Also, Keith is wrong. For one thing, an iPad doesn't have a C:\, and second, that's just not how networking works. (You'd have to share those resources over the network.)
