What does the acronym "VPN" stand for?

The acronym "VPN" stands for Virtual Private Network. This terminology is fundamental in cybersecurity and networking as it describes a technology that creates a secure connection over a less secure network, such as the internet. A VPN allows users to send their data securely by establishing an encrypted tunnel between their devices and the VPN server. This way, sensitive information remains private and protected from potential intruders.

Using a VPN is particularly important for maintaining privacy while using public Wi-Fi networks, as it helps to protect against unauthorized access to personal data. The technology is also used to circumvent geographical restrictions and maintain anonymity online, adding another layer of security for users.

The other options do not accurately reflect the established definition of VPN within cyber security and networking contexts. While they may sound plausible, they do not correspond to the widely accepted terminology used in the industry.
