Which topology is characterized by nodes radiating around a central node in a spoke-like fashion?

The star topology is characterized by nodes radiating around a central node in a spoke-like fashion. In this configuration, each peripheral device connects individually to the central node, typically a switch or hub. This arrangement allows for easy addition or removal of devices without disrupting the entire network, as each node operates independently while still being connected to the central point.

The central node acts as a mediator for data transmission, which can enhance network reliability and management. If one node fails, it does not affect the others since they are all independently connected to the hub. This is a key advantage of the star topology over other types, such as the bus topology, where a failure in the main cable can disable the entire network. The distinct spoke-like appearance is a defining feature of this topology, visually representing how nodes are arranged around a central connection point.
