incorporating the star topology with an extended topology. I would do this because I can upgrade the network by replacing the problem components such as the 10mbs Ethernet hubs and the existing cables. I would replace the hub with a gigabit switch and add gigabit wireless router for the five computers to connect to the network. I would replace the 10 computer network interface cards with a 10/100/1000 Mbps NIC and replace the old cable with cat6 Ethernet cables and the five additional computer with wireless
