How Does VPN Work in network system?

 A VPN is a way to connect to the internet through an encrypted connection. When you access a website, upload data to an app or check your email, the VPN encrypts all your communications and sends them to a server run by the VPN provider, which then sends them on to their destination.

That is useful for preserving your privacy when you don't trust the network you're on, whether it's an internet service provider or a Wi-Fi connection at an airport or coffee shop. You can also use a VPN to connect to a corporate network for work purposes. Many companies use this method to limit access to their internal networks to employees with VPN usernames and passwords and to encrypt their connections to work machines.

How Does VPN Work?

A VPN encrypts all the data you send from your computer across the internet, shapes it into specially formatted packets of data and sends them to the VPN server. The server has digital keys it can use to decrypt the data, but anybody else without these keys won't be able to read the data you transmit.

The server then routes the data to its destination, whether it's a work computer on your corporate network or another server on the internet. When you receive a response from the destination machine, it is routed to the VPN server, which encrypts the data and sends it back to your computer or phone, where your VPN software decrypts it.

The VPN server hides your computer's internet address and location and makes it harder for people to eavesdrop on you.
