What defines a "network" in computing?

• A. A single computer used for data processing
• B. A collection of connected devices that share resources
• C. A type of software application
• D. An isolated system without external connections

Answer: (B)

A network in computing is defined as a collection of connected devices that share resources. This interconnectedness allows devices such as computers, printers, servers, and smartphones to communicate with each other and share data, applications, and hardware resources like printers or internet connections.

This collaborative nature of networks enables users to access shared information and perform tasks collaboratively, enhancing efficiency and productivity. The concept of resource sharing is fundamental to what makes a network functional, as it supports various protocols and technologies that facilitate communication and data transfer among the devices involved.

In contrast, a single computer used for data processing represents an isolated instance of computing rather than a network. A software application, while it can be designed to facilitate tasks within a network, does not define the structure or purpose of a network itself. An isolated system without external connections refers to a situation where no communication or resource sharing occurs, which fundamentally contradicts the very definition of a network.
