What does the acronym VPN stand for?

The acronym VPN stands for Virtual Private Network. This technology creates a secure, encrypted connection over a less secure network, such as the Internet. By using a VPN, users can extend a private network across a public network, allowing them to send and receive data as if their devices were directly connected to the private network. This is particularly valuable for maintaining privacy and security while accessing the Internet, especially on public Wi-Fi networks, as it helps protect sensitive data from potential eavesdroppers.

The other options do not accurately describe the functionality or purpose of a VPN. For instance, "Variable Private Network" and "Value Protection Network" do not represent established networking concepts, while "Viewable Public Network" contradicts the primary purpose of a VPN, which is to ensure privacy and security rather than making the network public and accessible.
