what is a vpn打不开
A VPN, or Virtual Private Network, is a technology that ensures secure and private internet connections. It allows users to create a private network over a public network (the internet), shielding their online activities from prying eyes. VPNs encrypt users’ data, making it unreadable to anyone attempting to intercept it. This encryption ensures that sensitive information, such as passwords, financial details, or personal data, remains secure while navigating the web. Furthermore, VPNs mask a user’s IP address, providing anonymity and protecting against identity theft. VPNs are increasingly popular due to their ability to enhance online privacy and internet security, especially when using public Wi-Fi networks.#34#
