Virtual private network

What is VPN?

A virtual private network extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. 

Origin of VPN:

For as long as the internet has existed, there has been a need for protocols to keep data private and secure. 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.
