These are linux (and other unix versions) based systems that are on the Internet and offer free shell accounts. So you can (I guess) ssh to them, login, and get a shell prompt. If you had no other linux system, this is a way to access one to learn about it.

You are currently on a linux system. But you cannot ssh to it and get a shell prompt. Only the admins, Neo and Scott can do that.
