              Public to be used when using a public Internet connection, for example

"Public" Network Profile: -more secure
                          -  turn off sharing and not allow others to see your computer
"Home" Network- win7 network.Mixed XP,Linux or Max could be dangerous
              -like an open network, joined by a SINGLE password and supports media sharing
"Work" Network- is XP style file sharing- with username and pass to connect to other comps
              -is safe because is controlled by user account and share permissions, for example
              in mixed OSs cases.
