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

VPN stands for Virtual Private Network, and its primary purpose is to create a secure internet connection. By utilizing encryption and tunneling protocols, a VPN allows users to send and receive data across shared or public networks as if their devices were directly connected to a private network. This security feature protects sensitive information from potential threats, such as hackers or other entities that might intercept data traffic.

Furthermore, a VPN helps mask users' IP addresses, enhancing their privacy and allowing them to access region-restricted content by making it appear as if they are browsing from a different location. This ability to safeguard data and maintain confidentiality on public networks is crucial in today's digital landscape, where cyber threats are prevalent.
