I have noticed that when I'm on campus I can login to my account on any computer that's part of the network, and it feels exactly like using a local account on a normal home pc. By that I mean that when I turn the machine on, the login screen appears, I enter my username and password, and then almost instantly the desktop appears and everything is there, all my files, software, even the browser's history.
Obviously every computer doesn't have a few thousands accounts and doesn't store every user's data, so how is that possible? I can't seem to find anything like that in Google. Mostly because I don't really know what to look for. If I had to guess I would say that the data and accounts are stored on a central server and the computers download everything each time an users accesses his account, but it seems like an awful lot of traffic.
Any ideas? All of the machines use Linux Mint, by the way.
