The acronym 'VPN' stands for Virtual Private Network. A VPN creates a secure connection over the internet by encrypting data and masking the user's IP address, providing enhanced privacy and security. Users can connect to the internet through a remote server, making it appear as if they are accessing the web from a different location. This technology is widely used for secure remote access, bypassing geo-restrictions, and protecting sensitive information from potential hackers, especially on public Wi-Fi networks.
