VPN stands for Virtual Private Network. It is a technology that creates a secure and encrypted connection between a user's device and the internet, enhancing online privacy and anonymity. VPNs are commonly used to protect data transmitted over public Wi-Fi networks and to help users bypass geographical restrictions on content. By masking the user's IP address and routing their internet traffic through a secure server, VPNs ensure that sensitive information remains private and secure from potential threats and surveillance.
