VPN stands for 'Virtual Private Network' in short it is a private network build on internet.

[jack]

Yeah, a VPN is build using public wires (Internet) but restricted to specific users withing that networks only.

[Alexander]

The main purpose of setting a vpn is to make it enable to access a specific resource to limited people who are located at different locations.

[Hector]

Its true that the same public infrastructure is used by VPN but with a distinct privacy through specific tunnels i.e. L2TP.

[Travis]

Its totally dependent upon encryption and decryption as it encrypts data before delivering it through the tunnel and decrypt it at the receiving end.

[Alexander]

Improper encrypted data can not be sent so addition security is involved with it. Also the addresses of receiving end are always checked strictly.

VPN appeared as a best replacement for old popular WAN (Wide Area Network), maintaining a WAN is very expensive as it is totally depends on the distance between the two users.

[oliver]

Yeah, WAN is till I would call limited for a restricted area whereas VPN has no such boundaries.

[Ajay]

Yeah, WAN is till I would call limited for a restricted area whereas VPN has no such boundaries.

VPN is a great utility for those businesses which have their offices located at different geographical areas and want to carry communication among them.
