What does VPN stand for in networking?

VPN stands for Virtual Private Network, and it refers to a technology that creates a secure and encrypted connection over a less secure network, such as the Internet. This connection allows users to send and receive data as if their devices were directly connected to a private network. The security aspect of a VPN is particularly important for protecting sensitive information and maintaining privacy when using public networks.

The term "Virtual" indicates that this type of network does not require the physical infrastructure a traditional private network would need; instead, it uses encryption and tunneling protocols to establish private connections within the public realm of the internet. The word "Private" emphasizes that the communications over a VPN are shielded from the public eye, providing confidentiality and data integrity.

Using a VPN has become essential for many individuals and organizations to safeguard their online activities, to access restricted content, and to maintain anonymity while browsing the web.
