Which characteristics are typical of network operating systems?

Network operating systems are specifically designed to manage resources and facilitate communication among multiple devices within a network. This includes coordinating tasks such as file sharing, printer access, and user authentication across different machines. The essence of a network operating system lies in its ability to efficiently handle multiple devices simultaneously, allowing users to connect and interact with shared resources seamlessly.

The other characteristics listed do not align with the primary functions of a network operating system. Systems designed solely for individual computers are not equipped to handle the complexities of a network, while a focus solely on application performance overlooks the fundamental role of resource management. Additionally, modern network operating systems typically support internet connections, which is essential for enabling networked devices to communicate both locally and globally.
