:Cable failure,any place will be affected.

One way system so not affected by substantial traffic.

Explain what a star network is and how it works

N a star network topology,all nodes are connected with each other through one or more switches.

Easy to install and expands with extra nodes.

Uses of the most cable which is way expensive,an extra hub or switch further increases the cost.
