A virtual private network (VPN) is some sort of network arrangement that extends a private network and generally the resources that are contained in the network through public networks such as the Web. This is what enables a host terminal or computer to send out and receive data throughout a public or even shared network. It acts as if the connections and configurations were exclusive with all aspects of protection, functionality and of course management policies being part of the network. This is generally done by dcreating a point-to-point connection using truly dedicated connections, data encryption or a combination or even the two.
