Definition
A regular phyiscally existing network consisting of cables and routers/switches/etc is called a network. You run the various known internet protocols layer 1-4 on it. You can also use those protocols to emulate a virtual network. This is mostly done in layer 2 (IP). You tunnel the data of the virtual network encapsulated in IP-Packets for example. If you secure your tunnel as well with various encryption methods one might call the tunneled data a virtual private network. This is used in various scenarios, mostly for tunneling sensitive information over an inherently insecure architecture - for example to connect two corporate LANs over the internet.
