What is a VPN?

A VPN, or Virtual Private Network, is a technology that creates a secure connection over a public network, such as the Internet. By encrypting data and masking the user's IP address, a VPN provides privacy and anonymity while enabling secure communication between remote users and a private network. This is particularly useful for businesses that need to ensure that sensitive information is transmitted securely, even when employees are working remotely or using public Wi-Fi networks.

The term "private" in Virtual Private Network signifies that the data being transmitted is not visible to unauthorized users, which is essential for maintaining confidentiality and integrity. In contrast, the other terms in the choices, such as "Public" or "Node," do not accurately reflect the core function and purpose of a VPN, which is to create a secure, private channel for data transmission.
