wQuestion: Can we increase the maximum cable lenght as many times as we wish by just adding repeaters?
wAnswer: No
–Every repeater introduces a delay
–Access mechanisms such as CSMA/CD does not work with long delays
–Ethernet standard specifies that any two stations cannot be seperated by more than four repeaters
