What does the acronym VPN stand for, and what is its purpose?

The acronym VPN stands for Virtual Private Network. The primary purpose of a VPN is to provide a secure connection over a less secure network, such as the Internet. VPNs encrypt the data transmitted over the network, which helps protect sensitive information from eavesdroppers and unauthorized access. This secure tunnel allows users to browse the web privately, access remotely stored data, and maintain confidentiality in communications, making it particularly useful for remote work or accessing resources on a private network.

By using a VPN, users can connect to a private network as if they were physically present in that location, which can also help bypass geographical restrictions on content. This capability enhances security and privacy significantly compared to using an unprotected network. The other options do not accurately capture the essence or functionality of a VPN, as they either misstate the acronym or focus on irrelevant purposes.
