What is a network defined as in computer terminology?

In computer terminology, a network is defined as a group of two or more computers that are linked together to share resources and information. This definition encompasses a variety of configurations where computers can communicate with one another, whether through wired or wireless means. Networks can range from small local area networks (LANs), connecting a few devices within a limited area, to larger wide area networks (WANs) that span significant geographical distances. The primary function of a network is to enable the sharing of data and resources, such as files and printers, thereby improving efficiency and collaboration among users.

The other options do not meet the definition of a network. A single computer lacks the interactive component necessary for a network. Any hardware device could be part of a network but does not by itself constitute a network. Similarly, an internet connection is a service that allows access to the internet, but does not define a network in the context of computers sharing information among themselves.
