what is a vpn and how do that work?

Answer 1

It's a secure, private network in which one computer sends ENCRYPTED information to another computer (usualy sent to a server). A lot of businesses use VPN's like Medical Transcription, etc.
It encrypts data by changing a letter like d to something else like c. Then no one exept the receiving end has any idea how to decode it, but sometimes there are errors in the encryption process.

Answer 2

A VPN is a Virtual Private Network. Computers in the VPN can communicate even though they are not physically connected.

There are a couple of types of VPN: Remote Access and Site-to-Site.
Remote Access means that computer A can connect to computer B, but not vice-a-versa.
Site-to-Site means that computer A can connect to computer B, and computer B can connect to computer A.

Computers in a VPN are called VPN sites.
Communication between VPN sites is encrypted.

A lot of companies use VPNs to enable their employees to connect to the office computers and resources remotely.
For example, your home computer could be computer A, (a remote access VPN site) and connect to the office computer B (a VPN server). This would enable you to work from home.
(In this case, you'd like a Remote Access VPN connection, because you don't want computer B to connect to computer A... within the office, you might want to configure Site-to-Site)
