A third LAN configuration, the bus configuration, is a peer network with a break in the ring. As illustrated in Figure 3-3c, all network workstations are connected to a common cable or telephone line (the "bus") that stretches from end to end. Each
workstation in a bus configuration is independent, so failure of a single microcom-
puter does not disrupt the remainder of the network. By contrast, an inoperable workstation in a ring configuration causes the entire LAN to be inoperable.
