EIGHT SEGMENT BRIDGE
Appendix C. Segment Distance
The IEEE 802.3 CSMA/CD specification has defined standards which are differentiated by the oper-
ating link, the type of signaling, the type of media and distances supported. The following chart
highlights the characteristics of the major standards:

When viewing this chart remember that 10Base5 and 10Base2 use bus topology where multiple
devices tap into a segment. 10BaseT and the various 10BaseF implementations use star topologies
where individual devices connect to a repeater or hub via a single cable or segment. The various
topologies can be interconnected within a single network.
