A Guide to Understanding Virtual Private Network (VPN)

What is a Virtual Private Network (VPN)?
A VPN is a technology that creates a secure and encrypted connection over a less secure network, such as the internet. VPN technology was developed as a way to allow remote users to securely access corporate applications and other resources.

Why is a VPN important?
A VPN is important because it provides security by hiding your IP address, encrypting data transfer, and masking your location. It also provides privacy as it makes your activities anonymous.

How does a VPN work?
A VPN works by routing your device's internet connection through your chosen VPN's private server rather than your internet service provider (ISP) so that when your data is transmitted to the internet, it comes from the VPN rather than your computer.

Virtual Private Network (VPN) practice test

A Virtual Private Network (VPN) is a technology that enables secure communication over an unsecured network by encrypting data and tunneling it through remote servers. VPNs can be useful for businesses to establish secure connections between remote employees or offices and a central server. Endpoints are authenticated, and data is encrypted to prevent unauthorized access or eavesdropping. VPNs can also protect users' privacy by masking their IP addresses and location, as well as bypass geo-restrictions imposed by certain websites or services. Some common VPN protocols include OpenVPN, L2TP/IPSec, and IKEv2.
