A VPN (Virtual Private Network) is a technology that creates a secure, encrypted connection between your device and the internet.when you use a VPN, your internet traffic is routed through a remote server, which hides your real IP address and protects your data from being monitored.

VPNs are commonly used to improve online privacy, secure connections on public Wi-Fi, and access the internet more safely.

How a VPN works?

A VPN works by creating an encrypted tunnel between your device and a VPN server.when you connect to a VPN:

1.Server Connection. Your device connects to a VPN server.

2.Traffic Encryption. Your internet traffic is encrypted before leaving your device.

3.Secure Tunnel. The encrypted data travels through a secure tunnel.

4.Data Routing. The VPN server decrypts the data and sends it to the destination website. Because the traffic passes through the VPN server, your real IP address is hidden and your online activity is protected from many types of tracking or monitoring.
