Final answer:
Each node in a star network is connected to a central switch, and it receives packets specifically meant for it, or broadcast packets intended for all devices.
Step-by-step explanation:
In a star network, each network node is connected to a central device called a switch, where each device sees only those packets that were sent specifically to it as well as broadcast packets sent to all devices on the network. This kind of setup ensures that traffic is directed to the designated devices, which can reduce the chances of a data collision because data packets are not widely dispersed across the network as they would be in other network topologies.
