What is Star Toplogy, Advantages and Disadvantages of Star Topology

External Resources

Star Topology

A star topology is designed with each node (like workstations, printers, laptops, servers etc.) connected directly to a central device called as a network switch. Each workstation has a cable that goes from its network card to a network switch.

Most popular and widely used LAN technology Ethernet currently operates in Star Topology.

Star Network Topology

 

Advantages of Star Topology

Easy to install and wire.

No disruptions to the network when connecting or removing devices.

Easy to detect faults and to remove parts.

Disadvantages of Star Topology

Requires more cable length than a linear bus topology.

If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in network communication.

More expensive than linear bus topology because of the cost of the connecting devices (network switches).
