Question

How does Virtual Private Network work? Write applications of VPN.

Answer 1

A virtual private network (VPN) is programming that creates a safe and encrypted connection over a less secure network, such as the public internet. A VPN works by using the shared public infrastructure while maintaining privacy through security procedures and tunneling protocols. In effect, the protocols, by encrypting data at the sending end and decrypting it at the receiving end, send the data through a "tunnel" that cannot be "entered" by data that is not properly encrypted. An additional level of security involves encrypting not only the data, but also the originating and receiving network addresses.
