Does anyone know how a VPN work?

Yes of course, A VPN uses internet to create a secure and private connection between a device and the internet service the user uses. A VPN works like a shielded tunnel sending and receiving data under protection of that tunnelling which is the work of encryption. A VPN does not let anyone intercept the data of a user by forming the data into encrypted data, which no one can read.
