Where data is transmitted directly on the shared cable without any intermediary device actively boosting the signal

Explanation

• In a Star Network Topology, each network node (computer, printer, etc.) is connected to a central device called a hub or switch.
• This central device acts as a connection point for all the nodes, and data transmission occurs through it. 
• This topology is called a star topology because the connections resemble a star, with the hub at the center and the nodes at the points.
