For example, with Microsoft Office, ASU basically has a one-to-one ratio. For every computer that's connected to that server, there is a license for Office. The assumption is that it's likely that everybody in the room could be using Office at the same time. If you use an application that doesn't have a one-to-one ratio, it is possible to run out of site licenses. If this happens, you get the message that says, "Sorry, all the licenses are used." If this happens, you have to wait until somebody logs off so that it frees up a license so you can access one.
