What is a VPN and How Does It Work?

A VPN (Virtual Private Network) is a tool that creates a secure, encrypted tunnel between your device and the internet. This prevents third parties, such as hackers, ISPs, and even governments, from tracking your online activities.

Here’s how a VPN works:

✅ Encrypts Your Internet Traffic – Keeps your browsing history private.

✅ Hides Your IP Address – Makes it difficult for websites to track your real location.

✅ Unblocks Geo-Restricted Content – Allows access to streaming services and websites blocked in your region.

✅ Provides Public Wi-Fi Protection – Prevents hackers from stealing your data on unsecured networks.
