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).Why would you use a star topology?
A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.Where does star topology usually used?
Star Topology is the most common type of network topology that is used in homes and offices. In the Star Topology there is a central connection point called the hub which is a computer hub or sometimes just a switch.
