9.2.3. Ethernet
Ethernet is a very popular local area network architecture based on the CSMA/CD access method. The
original ethernet specification was the basis for the IEEE 802.3 specifications. Typically, ethernet networks
can use a bus physical topology, although, many varieties of ethernet such as 10Base-T uses a star
physical topology and a bus logical topology. (Microsoft uses the term "star bus topology" to describe
10Base-T)
