In networking, what does VPN stand for?

VPN stands for Virtual Private Network, which is a technology that creates a secure connection over a less secure network, such as the Internet. This secure tunnel encrypts data being transmitted, ensuring privacy and security for users. A VPN is commonly used to allow remote users to securely connect to a private network, protecting sensitive information from potential intruders and providing anonymity by masking the user's IP address.

The other options do not accurately describe the function or purpose of a VPN. For instance, "Variable Packet Network" and "Value Packet Network" do not relate to established concepts in networking, thereby lacking relevance. "Virtual Public Network," while it sounds similar, incorrectly emphasizes "public" rather than "private," which is central to the VPN's capability to safeguard communications.
