VPNs – How Do They Work

Definition and Purpose:

A VPN is a service that creates a private, secure network over a public one.
It encrypts your data and hides your IP address by routing your network activity through a secure chain to a server miles away. This can make it appear as if you’re in a different location, allowing you to access content that may be restricted in your area.

How VPNs Work:

Encryption: VPNs use advanced encryption protocols and secure tunneling techniques to encapsulate all online data transfers.
Tunneling: This process involves sending your data through a VPN server, which acts as a data relay. It hides your IP address and physical location.
Protocols: Common VPN protocols include OpenVPNs, PPTP, L2TP/IPSec, and more recently, WireGuard.

Security and Privacy:

VPNs enhance online privacy by masking user identities and locations.
They secure data against hackers on public Wi-Fi networks.
VPNs also prevent your ISP (Internet Service Provider) from tracking your online activities.
