What is VPN?

This is a technology that will protect your internet from surveillance, censorship, and intruders. The abbreviation stands for a Virtual Private Network.

It is virtual only because all computers and servers of this network are interconnected by virtual encrypted communication channels and not by a physical cable.

Such a network has internet access. When you connect to this virtual private network, you also get internet access: secure, with the change of IP address to anonymous.
