How VPNs Work:

VPN, or Virtual Private Network, is a technology used to secure internet communication over the internet. It allows users to access the internet, protect their personal information, and maintain privacy online.

1. Client-Server Model: A VPN can be set up with a server that offers a secure connection to the internet, and a client that allows you to connect to this server. This allows users to access the internet from any device on the same network, even if the device is not connected to the actual internet.

2. Remote-Server Model: In this model, a user connects directly to a remote server that offers internet access but does not allow access to the internet itself. This is often used for file transfer or video hosting.

3. OpenVPN: This is a client-server model that allows users to create a private network over the internet, making it possible to connect to other users on the same network.
