What does the acronym VPN stand for?

The acronym VPN stands for Virtual Private Network. This term describes a technology that creates a secure and encrypted connection over a less secure network, such as the Internet. By using a VPN, users can protect their online activities from eavesdropping, maintain privacy while browsing, and access region-restricted websites and services.

In this setup, "Virtual" indicates that the network is not a physical installation; it is a simulated environment created through software that uses public infrastructure. The "Private" aspect refers to the encrypted connection that limits unauthorized access to the data being transmitted. "Network" encompasses the interconnected systems that facilitate this secure communication.

Understanding this definition is crucial for networking and security professionals, as it highlights the importance of maintaining privacy and security in a connected world.
