The purpose of a VPN (Virtual Private Network) in internet usage is to create a secure and encrypted connection over a less secure network, such as the internet. This technology masks a user’s IP address, enhancing privacy and allowing for anonymous browsing. VPNs are commonly used to access region-restricted content and provide an additional layer of security when connecting to public Wi-Fi networks. By encrypting data transmissions, a VPN helps protect sensitive information from potential cyber threats, ensuring that users can browse and communicate safely online.
