Ethernet. Bus toplogy or star?
Posted on 2004-11-25
Im taking some practice CCNA exams, and one of the questions was : "is ethernet bus topology or star?"
I think it is bus correct? Bus is when all hosts are connected (one collision domain one broadcast domain). And CDMA is used to prevent collisions. This is how ethernet was designed right?
Now the thing that is throwing me off, is switches. Switches give point to point connections which allows hosts to communicate at the same time. And no CDMA is used.
Is ethernet bus topology when using a hub and star toplogy when using a switch? Or, does the switch simply just "cheat the system" by creating several collision domains...kind of fooling ethernet?
