What term describes the mapping of a physical network and logical interconnections between nodes?

The term that describes the mapping of a physical network and logical interconnections between nodes is known as network topology. Network topology refers to the arrangement of different elements (links, nodes) in a communication network. It can describe both the physical layout—the actual placement of cables and devices—and the logical layout, which involves how data flows across the network. Understanding network topology is essential for troubleshooting, optimizing network performance, and planning expansions or modifications.

In contrast, network design generally focuses on the planning stage where the requirements and components of the network are determined, while network architecture refers to the overall structure and organization of the network, including its components and their interactions. Network layout tends to describe the physical layout but does not fully encompass logical interconnections, which are critical to understanding how data moves across the network. Thus, while all these terms are interconnected in the realm of networking, network topology specifically captures the comprehensive mapping of both physical and logical structures.
