The acronym "VPN" stands for Virtual Private Network. A VPN is a technology that creates a secure, encrypted connection over a less secure network, such as the internet. It allows users to send and receive data as if their devices were directly connected to a private network, ensuring privacy and security. By masking the user's IP address and encrypting data, VPNs protect sensitive information from potential eavesdroppers, making them valuable tools for both individuals and organizations. VPNs are commonly used to bypass geographic restrictions, safeguard personal data on public Wi-Fi, and enhance overall online security.
