What is defined as a group of two or more computers connected to facilitate communication and resource sharing?

A group of two or more computers connected to facilitate communication and resource sharing is defined as a network. The primary function of a network is to enable devices to communicate with one another and to share resources such as files, applications, and internet connections. This can occur over various distances and through different configurations, from local area networks (LANs) that serve multiple devices in a small geographical area, to wide area networks (WANs) that may span large distances.

In contrast, the term "web" typically refers to the World Wide Web, which is a system of interlinked hypertext documents accessed via the internet, rather than a physical or logical connection of computers. "Cloud" represents a model for enabling convenient on-demand access to a shared pool of configurable computing resources, but it is not specifically about inter-device communication in the same manner as a network. "Router" refers to a device that forwards data packets between computer networks, serving as a traffic director, but it does not encompass the broader concept of interconnected systems for communication and resource sharing that defines a network.
