What defines the physical arrangement of devices in a network?

The term that defines the physical arrangement of devices in a network is topology. Network topology refers specifically to the layout or organizational hierarchy of interconnected devices in a network. It describes how different nodes (like computers, switches, and routers) are physically or logically connected and how they communicate with each other. Common types of network topologies include star, ring, bus, and mesh, each of which has its own unique arrangement and implications for performance and reliability.

While architecture refers to the overall design framework and structure of a system, including its components and their interactions, it is broader and encompasses more than just the physical arrangement. Infrastructure pertains to the foundational systems and services that support the network, like wiring, servers, and network switches, but does not specifically describe the arrangement itself. Configuration involves the settings and parameters applied to devices within the network, which can affect functionality and performance but does not define how those devices are arranged. Therefore, topology is the precise term used to articulate the physical layout of devices within a network.
