Which of the following is a common type of physical network topology?

The choice of star topology as a common physical network topology is well-founded. In a star topology, each node (such as computers, printers, or other devices) is connected to a central hub or switch. This central device serves as a point of management and communication, allowing for easy addition or removal of nodes without disrupting the entire network. One of the key advantages of the star topology is its reliability; if one node fails, it does not impact the rest of the network, as communication can still continue among other devices. This design also simplifies troubleshooting, since any disruption can usually be traced back to the specific connection to the central hub.

While other topologies like mesh, hybrid, and ring have their own advantages and use cases, the star topology remains one of the most prevalent due to its scalability and ease of maintenance. Mesh topology provides redundancy and can be complex to manage. Hybrid topology utilizes multiple topologies, thereby adding complexity without a singular focus. Ring topology processes data in a circular manner, which can cause issues if any single connection fails. Overall, the simplicity and effectiveness of the star topology make it a favored choice in many networking scenarios.
