As the name suggests, a Virtual Private Network is about privacy. It creates a network or a restricted system of communication between your device and the VPN provider. And that network is virtual because, unlike a "real" network, there is no pre-existing, dedicated infrastructure.
A virtual private network (VPN) refers to a network solution that is used to encrypt internet traffic and hide your IP address and virtual location from ISP and marketing website. It helps you stay secure and private when browsing.
Few people are familiar with VPNs already through their company or school, as using one is sometimes necessary to gain access to those organizations and resources.
But many people (including any individual) simply use a VPN to protect their privacy and improve their security on the Internet.
