What is a VPN? A VPN (Virtual Private Network) is a tool that helps protect your online privacy by creating a secure connection between your device and the internet. This means your data travels through an encrypted tunnel, making it harder for hackers or snoopers to see what you're doing online. VPNs are useful for accessing content that might be blocked in your country, like certain websites or streaming services. They also help keep your personal information safe when using public Wi-Fi. Whether you're a student, a traveler, or just someone who values privacy, a VPN can be a handy tool to have.
