From Wikipedia, the free encyclopedia

A virtual private network or VPN for short, is a way of connecting a computer to a remote network. Most people using computers connect to the World Wide Web using a normal network - they use dial-up or broadband. A VPN is a little bit different. It's used by some workers to connect to work using a laptop - they can check their work email and see work websites which can not be seen on the normal internet.[1]

VPN often offers anonymity by hiding the user and making it very hard for anyone to track them.[2]

Recently VPN is often used to access websites that are blocked in some countries, like China.[3]
