A Server Operating System (OS) is a specialized software that manages hardware and software resources on a server. Unlike regular desktop operating systems, server OSs are designed to handle multiple users and processes simultaneously, providing services such as file storage, web hosting, and database management. They ensure stability, security, and efficient resource allocation for various applications. Common examples of server operating systems include Linux, Windows Server, and Unix. These systems often come with features tailored for network management, user access control, and system monitoring. By optimizing performance and reliability, server OSs play a crucial role in supporting business operations and online services.
