Which type of operating system is specifically designed for network services and supports multiple users?

A server operating system is specifically designed to manage network resources and provide services to multiple users simultaneously. It facilitates the hosting of applications, storage solutions, databases, and various network services such as file sharing, printing, and web hosting. Server OS is built to handle increased workloads and prioritize requests efficiently, ensuring that multiple users can access the resources without significant performance degradation. This is essential for environments like businesses and data centers where reliability and multitasking capabilities are critical.

The other types of operating systems each have distinct roles and functionalities that do not align with the specific requirements of network services. For instance, a commercial OS primarily targets end-users, focusing on usability for individual tasks rather than multi-user network management. An embedded OS is tailored for specific devices, such as appliances or gadgets, and is not designed for user management across a network. Lastly, a real-time OS is optimized for processes that require immediate processing and responses, typically found in systems that need tight timing constraints, such as in industrial automation or medical devices, rather than in networked multi-user environments.
