What does VPN stand for?

VPN stands for Virtual Private Network. This term refers to a technology that creates a secure and encrypted connection over a less secure network, such as the Internet. The primary purpose of a VPN is to ensure privacy and security for users while they browse or access resources online, especially when connected to public networks.

In this context, the word "Virtual" indicates that the network is not physically constrained to specific geographical locations; it operates over the internet. "Private" signifies that the data transmitted over this network is not accessible by unauthorized users, providing a layer of security. "Network" refers to the interconnection of devices that communicate with one another, facilitating the transfer of data.

The other terms do not accurately define a VPN. Each contains elements that misrepresent its function or concept: "Variable Personal Network" and "Virtual Public Network" suggest public access or personal variability that does not reflect the secure nature of a VPN, while "Visual Private Network" introduces an unrelated aspect of visualization that is not relevant to network terminology. Thus, the definition of VPN as Virtual Private Network encompasses both its functional and technical aspects accurately.
