Pop Quiz! Q.1 VPN stands for… a) Virtual Public Network b) Virtual Private Network c) Virtual Protocol Network d) Virtual Perimeter Network

Pop Quiz! ,[object Object],b) Virtual Private Network VPN stands for… VPN stands for "Virtual Private Network" or "Virtual Private Networking." A VPN is a private network in the sense that it carries controlled information, protected by various security mechanisms, between known parties. VPNs are only "virtually" private, however, because this data actually travels over shared public networks instead of fully dedicated private connections.
