A Star network is one of the most common computer network topologies. In its simplest form, a star network consists of one central hub which acts as a conduit to transmit messages. In star topology, every host is connected to a central hub. A star network is an implementation of a spoke–hub distribution paradigm in computer networks.

Star Topology Advantages are as follows:

  • Several users can use the central unit at the same time.
  • It is easy to add new nodes and remove existing nodes.
  • A node failure does not bring down the entire network.
  • It is easier to diagnose network problems through a central hub.


Disadvantages are as follows:

  • The whole network is affected if the main unit “goes down,” and all communications stop. If it fails, there is no backup processing and communications capability and the local computers will be cut off from the corporate headquarters and from each other.
  • Cost of cabling the central system and the points of the star network together are very high.
