In a star topology, all computers are connected through one central device known
as a hub or a switch, as illustrated in Figure 1-6. Each workstation has a cable that
goes from the network card to the hub device. One of the major benefits of a star
topology is that a break in the cable causes only the workstation that is connected to
the cable to go down, not the entire network, as with a bus topology. Star topologies
are very popular topologies in today's networking environments.
