A VPN, or Virtual Private Network, is a technology that creates an encrypted connection between your device and the internet by routing your traffic through a remote VPN server. This process masks your real IP address, replacing it with one associated with the server’s location, which makes your online activity harder to track and your identity more difficult to identify. 

When you connect to a VPN, your internet traffic passes through an encrypted tunnel before reaching its destination. This means your ISP, network administrators, and most third parties cannot easily see what sites you visit or what data you send. VPNs are commonly used to protect privacy on public Wi-Fi, access region-restricted content, and add a layer of security when handling sensitive information.

VPNs do not make you completely anonymous online, but they are one of the most practical and widely used tools for reducing your digital exposure and securing your connection across networks.
