Detailed explanation-2: -Virtual Private Network (VPN) is a technology that allows establishment of an encrypted remote connection between two computers or networks. A VPN utilizes public networks to conduct private data communications.

Detailed explanation-3: -At its most basic level, VPN tunneling creates a point-to-point connection that cannot be accessed by unauthorized users. To create the tunnel, a tunneling protocol is used over existing networks. Different VPNs will use different tunneling protocols, such as OpenVPN or Secure Socket Tunneling Protocol (SSTP).
