What answer best describes network topology?

Network topology refers to the arrangement or configuration of various network elements, including devices, nodes, and connections, which collectively define how these components interact within a network. This concept encompasses both physical topology, which describes the actual layout of cables and devices, and logical topology, which explains how data flows within the network regardless of physical layout.

Understanding topology is essential because it influences network performance, reliability, and scalability. For instance, a star topology might offer more straightforward fault isolation than a bus topology, where a single point of failure could affect the entire network.

The other options focus on specific aspects that do not encapsulate the broad concept of network topology. For example, discussing only physical devices or types of media oversimplifies what topology represents. Similarly, referencing data transmission speeds relates to network performance rather than its structural layout, hence not adequately describing network topology.
