What is the primary function of a Network Operating System (NOS)?

The primary function of a Network Operating System (NOS) is to manage network resources. This includes facilitating communication between devices in a network, managing file storage, controlling access to resources such as printers and servers, and ensuring data flow between users and different hardware components. A NOS provides the necessary services and functionalities that allow multiple devices to connect, share data, and work collaboratively, which is essential in an environment where users need reliable network connectivity and resource management.

In contrast, designing graphics, providing internet access, and creating spreadsheets are functions associated with specific applications or systems, rather than the core responsibilities of a Network Operating System. A NOS does not focus on graphic design or spreadsheet manipulation; rather, it underpins the networking aspect of computing by organizing and administering networked resources effectively.
