What does VPN stand for and what is its main purpose?

VPN stands for Virtual Private Network, and its primary purpose is to provide a secure and encrypted connection over the internet. This technology allows users to create a private network across a public internet connection, effectively shielding their online activities from external threats. By utilizing encryption, a VPN protects sensitive data, such as passwords and personal information, ensuring that it remains confidential while transmitted across the internet.

In addition to security, VPNs also enhance privacy by masking the user’s IP address, making it more difficult for third parties, such as hackers or surveillance entities, to track their online behavior or location. This is especially important in today’s digital environment where data breaches and privacy violations are prevalent.

The other choices do not accurately describe the function or the definition of a VPN. For instance, the term "Virtual Proxy Network" does not exist and misleadingly suggests a focus on speed rather than security. Moreover, terms like "Virtual Protected Network" and "Variable Private Network" do not accurately represent the established terminology used within the field of networking.
