What generally characterizes a star topology in a network?

A star topology is characterized by having a single central node, which acts as a hub or switch, to which all other nodes (endpoints) are connected. This centralized arrangement simplifies the network layout and makes it easier to manage. If one of the peripheral nodes encounters a problem or goes down, it does not affect the other nodes, allowing for better reliability and easier troubleshooting.

When utilizing a star topology, adding or removing nodes can typically be done without disrupting the overall network, as connections to the central hub can be modified independently. This flexibility is one of the key advantages of a star topology, making it a popular choice for local area networks (LANs).

In contrast, the other options describe different network configurations that do not align with the characteristics of a star topology. For instance, a circular or ring configuration connects all nodes in a circular manner, while a linear path indicates a bus topology, where nodes share a single communication line. The interconnected nodes described in one of the choices suggest a mesh topology, where each node connects to multiple others directly. Thus, the distinctive feature of having a single central node connecting multiple endpoints defines the star topology.
