Star topology, each device has a dedicated point to point connection to a central 'hub'. There is no direct traffic between devices, all data travels via the central hub, which forwards it to the other connected devices. Each device in a star topology has only one I/O port and one link, making it less expensive and easier to install and maintain. There is also far less cabling to be housed, yet the links are still robust. The major draw back is the central point of failure - the hub. If this fails the whole network is out of action.
• all wiring is done from a central point (the server or hub)
• has the greatest cable lengths of any topology (and thus uses the most amount of cable)
• generally STP or UTP, four wire
