Ring/Token Ring The primary network cable is installed as a loop, orring,
and the workstations are attached to the primary cable at points on the ring.
The ring topology is the basis for the token ring network structure. Figure 20-9
illustrates a ring topology. On a token ring network, PCs are attached to devices
called multiaccess units, which are very similar to a hub, as in the arrangement
shown in Figure 20-8.
Star Each workstation is connected directly to the central server with its own
cable, creating a starburst-like pattern. The star topology, common to ARCNet
networks, is used today with both Ethernet and token ring networks to cluster
workstations with hubs, which are then attached to the primary network cable.
Figures 20-8 and 20-10 illustrate this arrangement.Chapter 20: Networks and Communications^525
