Final answer:
System topology refers to the layout pattern of interconnections among elements in a network, and it can be a layered, flattened, star, centralized, or distributed configuration.
Step-by-step explanation:
The system composition configuration as layered, flattened, star typed, centralized or distributed describes the topology of the system structure. Topology in this context relates to the arrangement of the various elements (links, nodes, etc.) of a computer network. Hence, system topology refers to the layout pattern of interconnections among the various elements that constitute a network.
