Which of the following are network operating systems and not simply operating systems that will communicate on a network?

Novell NetWare is recognized as a network operating system specifically designed to manage network resources and facilitate file and print services over a network. Its architecture was built from the ground up to provide robust support for multiple users accessing shared resources, emphasizing the networking capabilities that are central to its function.

In contrast, while Windows, Linux, and MacOS can operate on a network, they are primarily general-purpose operating systems that have networking capabilities. They allow communication over a network but were not exclusively designed as network operating systems. Their primary functions are broader, offering standard desktop or server capabilities along with networking features.

NetWare, on the other hand, is oriented toward providing a dedicated environment for network management, user account handling, and resource sharing, which illustrates why it stands out distinctly from the other options as a true network operating system.
