In the context of internet privacy, "VPN" stands for Virtual Private Network. VPNs create secure, encrypted connections over the internet, allowing users to browse privately by masking their IP addresses and encrypting their data. This technology is essential for protecting sensitive information when using public Wi-Fi or bypassing geographical restrictions on content. By rerouting internet traffic through a remote server, VPNs enhance online security, maintain user anonymity, and allow secure access to restricted resources.
