A virtual private network (VPN) is a network that is constructed using public wires — usually the Internet — to connect to a private network, such as a company’s internal network. There are a number of systems that enable you to create networks using the Internet as the medium for transporting data.It 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.
VPNs are widely popular as a means of securing sensitive data when connecting remote data centers. These networks are also becoming increasingly common among individual users and not just torrents. That’s because it use a combination of dedicated connections and encryption protocols to generate virtual P2P connections, even if snoopers did manage to siphon off some of the transmitted data, they’d be unable to access it on account of the encryption.
