Linux is widely known for its strong security features, stability, and efficiency, making it a preferred choice for servers, especially web servers that handle sensitive data. It has a robust permission system and a strong community providing timely updates and security patches. Windows might be considered for its user-friendly interface and extensive support but is not as commonly chosen for web servers with sensitive transaction data due to its licensing costs and different security model. macOS, while secure and stable, is less common in a server environment due to its primary design for end-user workstations and not as compatible with some server applications. Chrome OS is mainly designed for use with internet-connected applications and lightweight computing tasks and does not fit the server scenario well.
