GATE | GATE CS 2013 | Question 65
Determine the maximum length of the cable (in km) for transmitting data at a rate of 500 Mbps in an Ethernet LAN with frames of size 10,000 bits. Assume the signal speed in the cable to be 2,00,000 km/s.
Data should be transmitted at the rate of 500 Mbps. Transmission Time >= 2*Propagation Time => 10000/(500*1000000) <= 2*length/200000 => lenght = 2km (max) so, answer will be: (B) 2km
