vpn的意义

vpn stands for Virtual Private Network (VPN). It is a network designed to provide secure internet access over a public or private network. VPNs enable users to access remote servers or services from their home or work computer while maintaining privacy and confidentiality. They use encryption protocols such as HTTP, HTTPS, or IPsec to protect the connection, ensuring that sensitive data is protected even if the private network is compromised. VPNs are commonly used for remote access to servers, encrypted file sharing, and remote work environments.
