Detailed explanation-1: -A VPN uses tunneling protocols to encrypt data at the sending end and decrypts it at the receiving end. The originating and receiving network addresses are also encrypted to provide better security for online activities. VPN apps are often used to protect data transmissions on mobile devices.
Detailed explanation-2: -The encrypted connection helps ensure that sensitive data is safely transmitted. A VPN extends a corporate network through encrypted connections made over the Internet. Because the traffic is encrypted between the device and the network, traffic remains private as it travels.
