The acronym "VPN" stands for Virtual Private Network. A VPN creates a secure, encrypted connection over a less secure network, such as the Internet. This technology enables users to send and receive data as if their devices were directly connected to a private network. By establishing this secure tunnel, a VPN ensures that sensitive information is protected from interception and unauthorized access.

The term "virtual" refers to the fact that this private network is not physically defined by cables and hardware but rather is established through software and protocols. The 'private' aspect indicates that the VPN provides a level of privacy and security, safeguarding data traveling over public networks.

Other terms in the options, such as 'Variable' and 'Vulnerable,' do not accurately capture the concept of a VPN, as they do not pertain to the functionality of secure and private network connections. Similarly, "Virtual Public Network" incorrectly suggests that the network is public rather than private, which detracts from the fundamental purpose of a VPN. Overall, the definition and function of a Virtual Private Network make it essential for effective cybersecurity practices when accessing the internet or connecting to remote resources.
