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
10Base2 and 10Base5
follow what is known as the 5-4-3 rule,
which means that there can be only five
network segments in total, joined by four
repeaters (more on repeaters in Chapter
3), but only three of those network
segments can be populated with nodes.
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.
