VPN, in direct translation, means virtual private network in English and connects you remotely to a physical network where you are not. Although some use this technology to connect to their company’s local network as if they were there, it is a miraculous solution for the citizens on the road, who have to learn this concept just like DNS due to some necessities, allowing them to enter sites where VPN cannot be accessed.
How does a VPN work?
Although VPN uses many different protocols and technologies, it basically opens an encrypted (in the sense of crypto) tunnel to the opposite network from where your computer is physically located. Since the information transmitted through this tunnel is encrypted when viewed from the outside, it cannot be viewed from the outside. Well-versed security experts see encrypted data flowing but cannot understand what its content is (unless using very weak security). VPN solutions install a specialized network driver on your computer or mobile device (or come embedded in mobile devices) at which point it acts as a virtual network adapter, giving you an IP number from the other network. In this way, you can access allowed applications or local addresses.
