What is VPN – Virtual Private Network

In layman’s language, the Virtual Private Network mostly called VPN is a way to access the internet without being tracked. A VPN will also allow the user to visit the websites and servers which may be blocked in a particular location i.e. Geo-blocked. Normally when we access internet, we openly access the online data and are exposed to our IPS, govt agencies, online trackers and anyone who wish to track you down. This is because you are accessing the internet openly as there is direct connection between your device and the server.

Typical VPN process

When you use a VPN server, you are not directly connected to the target server, but are routed through a virtual server. The virtual server hides your identity and assigns a different identity to you (a different IP address and geo-location). This way the trackers will not be ale to find out your real location or IP address as you have not exposed it while on a VPN network. This is also called tunnelling (because you got a tunnelled connection which is hidden from others).
