What is VPN?

VPN - Virtual Private Network
VPN is a network technology that creates a secure network connection over a public network such as the Internet or a private network owned by a service provider. Large corporations, educational institutions, and government agencies use VPN technology to enable remote users to securely connect to a private network.

A VPN can connect multiple sites over a large distance just like a Wide Area Network (WAN).
VPNs are often used to extend intranets worldwide to disseminate information and news to a wide user base.
Educational institutions use VPNs to connect campuses that can be distributed across the country or around the world.
