As you learned in Chapter 2, the term “topology” usually refers to the way in which the com-
puters on a network are connected together. In a bus topology, for example, each computer is
connected to the next one, in daisy chain fashion, whereas in a star topology, each computer
is connected to a central hub. These examples apply to cabled networks, however. Wireless
networks don’t have a concrete topology as cabled ones do. Unbounded media, by definition,
enable wireless network devices to transmit signals to all of the other devices on the network
simultaneously.
