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.
(A)
1
(B)
2
(C)
2.5
(D)
5
Answer: (B)
Explanation:
Data should be transmitted at the rate of 500 Mbps.
Transmission Time >= 2*Propagation Time
=> 10000/(500*1000000) <= 2*length/200000
=> length = 2km (max)
so, answer will be: (B) 2km
