I think I understand the connectivity rule with Ethernet: 10Base2, 10Base5 and 10Base-T...
There are only maximum 5 segments between any two terminal nodes.
There are only maximum 4 repeaters between any two terminal nodes.
There are only three segments could be used to connect nodes.
There are two inter-hub segments could not be used to connect nodes.
There forms one collision domain that could contain maximum 1024 nodes.
How does this apply with Class I and Class II Repeaters and switches along with 100 base-TX? Is there even another newer class? Are the rules the same?
