1. (1 point) Consider a packet switching architecture. Which of the following components of delay is not considered when we use packet switching? a. Processing delay. b. Queuing delay. c. Transmission delay. d. Propagation delay. e. None of the above. 2. (1 point) In packet switching, all packets experience: a. Fixed bit rates at all nodes. b. Processing delays while traveling over a virtual circuit. c. Less total communication delay compared to circuit switching. d. All of the above e. None of the above. 3. (1 point) Transmission delay is_ a. The time needed to put the entire packet on the link and is dependent on the length of the packet b. The time needed to put the entire packet on the link and is independent of the length of the packet. c. The needed time for one bit to reach to the other end of the link is dependent on the length of the packet. d. The needed time for one bit to reach to the other end of the link is independent of the length of the packet. e. None of the above. 4. (1 point) If the receiver clock is 0.2 percent faster than the sender clock. How many extra bits per second does the receiver receive if the data rate is 200 kbps? a. 4 extra bits b. 400 extra bits c. 1000 extra bits d. None of the above
