What does the acronym VPN stand for?

The acronym VPN stands for Virtual Private Network. A Virtual Private Network is a technology that creates a secure and encrypted connection over a less secure network, such as the Internet. This secure connection enables users to send and receive data as if their devices were directly connected to a private network. The primary purpose of a VPN is to provide privacy and anonymity while browsing online, as well as to enable secure data transmission for remote users accessing corporate networks.

The other options don’t accurately reflect the definition of VPN. "Visual Private Network" and "Variable Private Network" do not exist in the context of networking concepts, as they do not convey the function or purpose associated with VPN technology. "Virtual Public Network" is also inaccurate because a VPN provides a private and secure connection, distinguishing it from public networks. Therefore, Virtual Private Network is the correct term and embodies the essential features of what a VPN represents in both personal and professional environments.
