Network Topology

Star Topology

Advantages and Disadvantages


  • The star network is very reliable
  • Very few data problems because each computer has its own cable to the network
  • Good security , no workstation can interact with another without going through the server first


  • The most expensive network layout to install because of the amount of wires cables needed
  • Installing the network usually needs experts to set it up because it is complicated

  • Extra hardware such as hubs and switches may be needed

  • If the server crashes or stops working then nobody will be able to access their files or use the network.

Information about the star network

Star networks are one of the most common computer network topologies. In its simplest form, a star network consists of one central switch, hub or computer, which acts as a conduit to transmit messages. This consists of a central node, to which all other nodes are connected; this central node provides a common connection point for all nodes through a hub. In star topology, every node is connected to a central node called a hub or switch. The switch is the server and the peripherals are the clients. Thus, the hub and leaf nodes, and the transmission lines between them, form a graph with the topology of a star. If the central node is passive, the originating node must be able to tolerate the reception of an echo of its own transmission, delayed by the two-way transmission time plus any delay generated in the central node. An active star network has an active central node that usually has the means to prevent echo-related problems.
