Which of the following defines VPN?

A Virtual Private Network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, such as the Internet. It allows users to establish private networks that can extend to multiple locations, providing confidentiality and privacy for data transmitted across public or shared networks.

By using a VPN, users can ensure that their online activities, data transfers, and communications remain private, making it difficult for outsiders to intercept or monitor their data. This is particularly useful for remote workers accessing company resources or individuals wanting to protect their personal information while surfing the web.

The other terms listed do not accurately capture the essence of what a VPN is. "Virtual Personal Node," "Verified Private Network," and "Virtual Process Node" do not refer to established concepts in network security and do not represent the primary function and features of a VPN, which focuses on creating a private, secure communication channel.
