What characterizes a star network topology?

This describes a linear or ring topology rather than a star topology. In such configurations, each device connects to only two others, creating a closed or open loop. This structure does not provide the centralized management characteristic inherent to star networks.

This is a description of a mesh topology, where each device is interconnected, allowing for multiple pathways for data transmission. While effective for redundancy and reliability, this topology lacks the singular central connection point that defines a star topology.

This statement describes a bus topology, where all devices share a single communication medium. Unlike star topology, where each device connects to a central point, bus topology relies on a single line for communication, making it less efficient in terms of troubleshooting and network management.
