A VPN connection is the extension of a private network that
includes links across shared or public networks, such as
the Internet. VPN connections (VPNs) enable organizations
to send data between two computers across the Internet in a
manner that emulates the properties of a point-to-point
private link.
Basically, a VPN is a private network that uses a public
network (usually the Internet) to connect remote sites or
users together. Instead of using a dedicated, real-world
connection such as leased line, a VPN uses "virtual"
connections routed through the Internet from the company's
private network to the remote site or employee.
