Virtual private network

Origin of VPN:

The history of VPN (virtual private network) technology dates back to 1996, when a Microsoft employee developed the peer-to-peer tunneling protocol, or PPTP. Effectively the precursor to modern VPNs, PPTP creates a more secure and private connection between a computer and the internet.
