What does 'VPN' stand for and its purpose?

The term ‘VPN’ stands for Virtual Private Network, and its primary purpose is to create a secure and encrypted connection over a less secure network, such as the internet. By using a VPN, users can safeguard their internet traffic from eavesdroppers and ensure their data privacy.

When a device connects to a VPN, it establishes a secure tunnel through which all internet traffic passes. This encryption helps protect sensitive data from being intercepted by others, making it a vital tool for anyone who wishes to maintain privacy and security while online. Additionally, VPNs can also allow users to access region-restricted websites by masking their real IP address, providing greater flexibility and access to content.

The other options do not correctly define VPN or capture its core functionality, making them less relevant. Understanding the correct definition and purpose of a Virtual Private Network is essential for appreciating its importance in cybersecurity and online activities.
