In a star topology, cable segments from each computer in the network are connected to a central component, the so-called hub/switch.
A hub/switch is a device that connects multiple computers. In a star topology, the signals are transmitted from the computer via the hub/switch to all computers in the network. In larger systems, several LANs can be connected to each other using a star topology.
- An advantage of the star topology is that if a computer in the star topology fails, only the failed computer cannot send or receive data. The rest of the network works as usual.
- The disadvantage of this topology is that if the hub fails, the entire network fails because each computer is connected to the hub. In addition, in a star topology, noise is generated in the network.
