Which of the following best describes a network?

A network is best described as a method of sharing information. Networks facilitate the connection and communication between multiple devices, enabling them to exchange data and resources. This interconnected structure allows users to share files, access shared applications, and utilize shared internet connections, enhancing collaboration and efficiency.

While a collection of databases, a type of operating system, or a single computer system may involve communication and data storage, they do not inherently describe the concept of a network. A collection of databases may reside within a network but does not capture the essence of connectivity among various devices. Similarly, an operating system governs a single computer's operation and resource management without directly representing the interconnectedness that defines a network. Lastly, a single computer system does not convey the idea of multiple systems working together to share information. The fundamental characteristic of a network is its ability to connect multiple computers or devices for the purpose of communication and resource sharing.
