A network is defined as a collection of computers and devices that are interconnected and capable of sharing resources. This includes sharing files, printers, internet connections, and other services. The primary purpose of a network is to enable communication and collaboration between different devices, enhancing productivity and efficiency. By connecting multiple computers and devices, users can exchange data and resources effectively, which is fundamental in both personal and organizational contexts.

The other options highlight related concepts but miss the comprehensive definition of a network. A single computer processing data refers only to an individual unit and does not encompass the collaborative aspect of networks. A software application for communication pertains to specific programs that may operate over a network but do not define the network itself. Lastly, a database of stored information describes a method of organizing data rather than a system of interconnected devices and systems. These distinctions underline why the definition that emphasizes interoperability and resource sharing is the most accurate in describing a network.
