1. Find the propagation delay for a signal traversing the following networks at the speed of light in cable (2.3 × 108 meter/second).

(a) metropolitan area, 100 km

(b) continent, 5000 km

2. How many (i.e. maximum) bits are in transit during the/a propagation delay (assuming the pipe is full) in the case (a) of Question 1 if bits are entering the network at the following transmission speeds:

(a) 1 Megabits/second

(b) 100 Megabits/second

(c) 10 Gigabits/second

Subject: Computer networks and chapter :packets 1.0. Suppose a link has a propagation delay of 20 µsec and a bandwidth of 2 bytes/µsec. (a). How long would it take to transmit a 600-byte packet over such a link? (b). How long would it take to transmit the 600-byte packet over two such links, with a store-and-forward switch in between? if there is a diagram please draw the diagram

The speed of signal propagation along an axon strongly depends on its two characteristics or parameters. What are they?

There are two types of propagation delay, identify and give their descriptions.

In a communication system, the transmission rate is 1Mbps, the two ways propagation delay is 1ms, and the processing delay is negligible. Given the frame length of nf=1250 bytes, ACK frame and frame overhead of 25 bytes, please find the Stop&Wait ARQ protocol efficiency with channel bit error rate of 10^-5 .

In propagation delay concept, what do Hold time and Setup time mean? (describe with an example)

Propagation Delay A satellite phone connects to orbiting satellites instead of terrestrial cell sites. When you speak into a satellite phone , the signal has to travel from you to the satellite, from the satellite to the other person, and all the way back from the other person to the satellite and then satellite to you. What is the round trip propagation delay when you use a satellite phone for communication? You may assume that the satellite orbits at a...

1 – Consider the car-caravan analogy. In this problem, assume a propagation speed of 70 km/hr and that each toll booth takes 6 seconds to service a car. Suppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 50 km to a second toll booth, then another 50 km to a third toll booth, and finally stops immediately after the third tool booth. Thus, they travel a total of 100 km. What is the...
