What is VPN, How Does VPN Work and Why use a VPN?
A VPN is a virtual private network that works within a specific set of computers and it can help you stay safe against the prying eyes that can be found online. The VPN will protect your computer pretty much like a firewall, although it does that in the online world. Even if the VPN is basically a WAN, it does retain the similar appearance, functionality and security that a private network has.
