What is VPN? How Does It Work?


VPN is a software that shows that smart devices such as phones and computers that you connect to the internet are in a different location. To do this, it opens an encrypted tunnel to the other network. This transferred information is shared mutually through the tunnel. This stream is a fully encrypted stream. Therefore, it cannot be viewed from the outside. In this way, the traffic flow takes place in the specified country. For example you can log in to the sites according to Canadian rules and procedures on the network trip, if you choose Canada. VPN software or mobile apps create a network drive system for you to access this private tunnel. Acting as a virtual network adapter, this software also forwards an IP address from the network you want to connect to. The IP address, in a way, creates the identity of your connection. With this ID, you can log into the networks of different countries.

How Does a VPN Work?

The VPN client works by creating a virtual network drive between two points. It then forwards an IP to the user from the opposite network. The user gains access to allowed connections with this IP. The network drive created by the VPN is encrypted. Therefore, those who have knowledge in this field know that the user exists. However, data transmitted over the network is not recognized because the network is encrypted. VPN connection hides online data traffic. Therefore, it also prevents them from being accessed from the outside. Unencrypted data can be viewed by anyone who has access to the network and wants to see it. With VPN, hackers and cybercriminals cannot decrypt or use this data.
