So, a virtual private network PC 免费梯子 is a technology that provides a secure (closed from external access) connection of a logical network over a private or public network with high-speed Internet.

This network connection of computers (geographically separated by a considerable distance) uses a point - to-point connection (in other words, "computer-to-computer").

Scientifically, this connection method is called a vpn tunnel (or tunnel Protocol). You can connect to such a tunnel if you have a computer with any operating system that has a VPN client integrated into it, which is able to "route" virtual ports using the TCP/IP Protocol to another network.
