VPN is short for Electronic Private Network and is a technology that creates an encrypted secure interconnection over a less secure network like the Net. The advantage is that it provides the security that the network on which it is based cannot provide. By using the internet to transport data. A large number of such networks can be created by using different systems incorporating encryption and other security mechanisms to ensure that only certified users can access the network and information may not be intercepted by the others. It can be like a canal built to transmit data between a network of say an organization and a remote user. That hides your data and IP address. vpn online
