for example,in ubuntu you can tell it to download and install updates automatically, if the update requires a reboot an icon will appear on the task bar telling you that updates have been installed that require a reboot.
but this is a configurable item. you can also tell it to download, but not install the updates, to just check if updates are available (and tell you if they are), or to leave it to you to do everything manually.
