Which topology allows messages to travel in a closed loop where each node reads addressed messages?

• A. Bus Topology
• B. Star Topology
• C. Full Mesh Topology
• D. Ring Topology

Answer: (D)

The choice of the ring topology is correct because it is specifically designed for allowing data to travel in a closed loop. In a ring topology, each node is connected to exactly two other nodes, forming a circular pathway for the data. When a message is sent from one node, it circulates around the loop until it reaches the intended recipient node. All nodes in the network receive the message, allowing them to read and process it based on the address contained in the message. This design fosters a straightforward method for transferring data, ensuring that messages pass through each node in one direction (or in some variations, both directions). The structured path of communication minimizes data collisions and helps maintain an orderly flow of information. In ring topology, the sequence of the data transmission is crucial to the operation and efficiency of the network, as each node must wait its turn to send or receive messages. In contrast, other topologies like bus, star, and full mesh have different structural characteristics and data transmission methodologies that do not create a loop in the same way, thus making them unsuitable for the description provided in the question.
