Computer Concepts Module 1 Practice Exam

The main idea being tested is that a computer network is a system of interconnected devices that can share resources and communicate with one another. This definition captures both aspects: linking devices so they can access shared things like printers or files, and enabling different devices to send information to each other, regardless of distance or medium. A single computer storing data locally isn’t a network because there’s no other device to share with or communicate to. A protocol for writing software describes development rules, not how devices connect and interact. A device that connects to the Internet only for emails focuses on a narrow use case rather than the broader idea of multiple devices sharing resources and communicating. Therefore, the option that describes a collection of devices connected to share resources and communicate best defines a computer network.
