How is a computer network defined?

A computer network is defined as a set of computers connected to share resources and information. This definition emphasizes the primary function of networks, which is to enable communication and resource sharing among multiple devices. In a network, computers can exchange data, access shared files or printers, and utilize internet resources collaboratively, which is essential for both individual and organizational efficiency.

The ability to share resources effectively distinguishes networks from single computers with multiple applications, as it involves multiple machines working together. Additionally, while software does facilitate connections between devices, it is not the essence of what constitutes a network itself; rather, the hardware configuration and interconnection of multiple computers create the network environment. Lastly, a collection of websites hosted on servers is more indicative of web infrastructure rather than a network, as it does not inherently involve the sharing of resources among multiple computer systems but rather refers to web-based content storage and delivery.
