A VPN or Virtual Private Network ensures the security and privacy of a private or public network. This is done by using a system or protocol whereby the user's computer is assigned a new IP address which is owned by the VPN. All of the Internet traffic of the user is channelled to the VPN server. Once there, it is decrypted and allowed to travel to the new IP address. The user's Internet service Provider will only see a single stream of encrypted data stream between the user and the VPN server. The ISP will not be able to log and monitor or control the user's internet usage.
