How is a network topology best defined?

A network topology is best defined as the structure of a computer network. This term refers to the arrangement or layout of different elements (nodes, links, etc.) within the network. It encompasses how various devices like computers, servers, and routers are interconnected and how data flows between them. Understanding the topology of a network is crucial because it affects the network's performance, stability, and scalability.

Other concepts like data transmission speed, communication protocols, and types of devices are important aspects of networking but do not directly define the term "topology." The speed of data transmission relates more to the network's efficiency, while protocols are rules that dictate how data is transmitted. The types of devices in a network pertain to the hardware involved but do not illustrate the overall structure and arrangement of those devices within the network itself. Thus, option B accurately captures the essence of what a network topology is.
