Final answer:
The correct answer is b. Token Ring, which is a network protocol using a token circulating in a ring topology allowing only the token holder to send data.
Step-by-step explanation:
The question refers to network architecture that uses a token placed in the data channel which circulates around the network. In this case, the correct answer is b. Token Ring. This network protocol operates by having a token, which is essentially a small data packet, circulate around the network nodes in one direction within a ring topology. Only the node possessing the token can send data, which helps prevent collisions and ensures orderly network traffic flow. In contrast, Ethernet typically uses a bus or star topology without a token and relies on collision detection. Wi-Fi, or wireless networking, uses radio waves to transmit data across nodes in multiple topologies but does not employ a token to regulate data transmission. Finally, Bluetooth is a short-range wireless communication technology that enables data exchange over short distances and does not use a token ring protocol.
