What system provides communication between nodes in a network?

The Network Operating System (NOS) is specifically designed to enable communication between nodes within a network. Unlike a general operating system that primarily manages the computer's hardware and software resources locally, a NOS provides the necessary protocols, services, and management tools to facilitate communication, sharing of resources, and the overall network functionality. This includes features like user authentication, file sharing, and centralized management of network resources, which are crucial for effective inter-node communication in a networked environment.

In contrast, an operating system serves a broader purpose in managing local resources on a single device, whereas a file system pertains to organizing and storing files on a storage medium, and a device driver functions as a translator between the device and the operating system, allowing hardware components to communicate with the software. These functions do not specifically address the essential requirements for networking capabilities among multiple nodes.
