What happens when a user logs off- is the computer disconnected from explorer- disconnected from the hard drive- disconnected from the net work - disconnected from power consumption?
This one is easy, the answer is the user is disconnected from
Windows Explorer and a partition of the hard-drive.
Windows Explorer is everything that allows you to navigate a
windows operating system: documents, taskbar, desktop... ect, so
when the user 'logs off' the computer, windows explorer process is
shutdown.
The user is also disconnected from the hard drive but the system
is not, this is because if there are multiple accounts on the
computer, then other accounts can access their personal space on
the hard drive.
Aslong as the computer is switched on, even at logon screen
power is still being consumed to run the computer's operating
system and files which are ready for the user to log back on.
