Question

Determine the length of the cable for transmitting data ata a rate of 500mbps in an ethernet lan with frame of size 10000 bits.assume the signal speed in the cable to be 200000km/s

Answer 1

Data should be transmitted at the rate of 500 Mbps.

Transmission Time >= 2*Propagation Time

=> 10000/(500*1000000)  lenght = 2km (max)

so, answer will be: ) 2km
