Final answer:
The correct answer is the client-server architecture, which features centralized processing on the server, and does not typically describe a network where data flows in one direction which would be a bus topology.
Step-by-step explanation:
The description provided fits the characteristics of a client-server architecture. In this type of network, the server hosts the processing power and logic, which services requests from the clients. This architecture is highly centralized with the server being at the core of processing and data management. On the other hand, a description that fits 'Resembles a group of computers in which data flows in only one direction from one device to the next' could be referring to a bus topology, which is a type of network where each computer or network device is connected to a single main cable or backbone. However, since a bus topology is not one of the provided options to choose from and the description is more focused on the server-side processing aspect, the correct answer is the client-server architecture.
