I have a couple of confusing problems on my course, so I decided to ask here. The question is:
What is the minimum size of Ethernet frame for a network speed of 100MBps* and maximal segment of 100 meters?
*Could be that this is actually 100Mbps (100BaseT), but doesn't matter a lot.
I thought 100 meters is the distance, so 200 meters is all around. I wanted to divide that by speed of signal, so I can get the time for one bit to come back, so I got 1 microsecond, and for 1 microsecond this network can send 100 Bytes (or 100bits if 100Mbps), which is what I thought was an answer.
My professor answered me that it's 500 meters in total, based on 5-4-3-2-1 rule, but I still don't get it. How do I measure it and is it 5 segments of 100 meters resulting in 500? Should I get 64B (Ethernet standard) as answer?
Also, if there is site more fitting for these kind of questions, feel free to redirect me.
