The 10Base2 Ethernet architecture is a network that runs at 10 Mbps and uses
baseband transmissions. 10Base2 typically is
implemented as a bus topology, but it could be
a mix of a bus and a star topology. The cable
type that we use is determined by the character at the end of the name of the architecture—in
this case a 2. The 2 implies 200 meters. Now,
what type of cable is limited to approximately
200 m? You got it; thinnet is limited to
approximately 200 m (185 m, to be exact). The
only characteristic we have not mentioned is
the access method that is used. All Ethernet
environments use CSMA/CD as a way to put
data on the wire
