Ethernet is not a topology. It is important to be careful and state what type of ethernet one is talking about. Traditional co-ax based etheret is a bus topology – you have a long wire with all the stations attached to it. Once we get into UTP Based ethernet we have to be careful. The use of a hub can lok like hub and spoke, or star topology, but functionally it is still a bus. When we replace the hub with a switch, we are into hub and spoke (or star) proper, as we have a device at the hub that controls the communication, but the L2 protocols in use are still ethernet. If we persist with the celeistial terminilogy, does that make a campus network (a number of switches interconnected) a galaxial topology? Sorry, I could not resist that last thought! Paul.
