2. Topology and termination
When the transmission rate is high or the distance among the equipments is big, it is very
important to pay attention in the topology and in the terminators. The most acceptable topology
is the “Daisy Chain". If the segments are not very long, the “Backbone” can be considered.
Backbone with stubs (workable)
Backbone with stars or clusters (avoid
)
