1.Virtual private networks create an encrypted "tunnel" between computer devices and host servers. A VPN is a private network that uses a public network to connect to remote sites or users. VPN networks use "virtual" connections routed over the Internet to remote sites from corporate private networks or third-party VPN services.
2. Your ISP or government agency can only see that you are connected to a VPN server, but cannot track your activities or IP addresses that you have accessed. With the help of 128-bit encryption, all data is completely hidden.
