subject

The objective of this exercise is to realize how high distance and high bandwidth affect the performance of stop and wait. The distance from Earth to a distant planet is approximately 9 x 10° km. Assume that the frame size is 8 Kbits and the speed of light is 3 108 m/s. Assume that the bit rate is 10 Mbps. a) What is the efficiency (channel utilization) if a stop-and-wait protocol is used?
b) Suppose we use a window protocol. What should be the window size in frames to achieve the maximal efficiency (channel utilization)?
c) Plot the efficiency versus the distance when the bit rate is set to 10 Mbps. Discuss this plot.
d) Plot the efficiency versus the bit rate when distance is set to 9 x 109 km. Discuss this plot.

This first part of the film shows the early history of motion pictures. how accurate do you think the portrayal of the early motion picture industry is? why? is historical accuracy important in films and theatre productions? explain. in the scene where don is going to the party (starting at time code 14: 51), we see a street scene as he first rides with cosmo and then with kathy. what aspects did the filmmaker include to make the scene look and feel like don, cosmo, and kathy are riding in a car on a street? think about elements such as scenery, sound, props, lighting, and so on. a "talkie" picture is shown starting around time code 21: 15. how does the audience in the film react to the "talkie"? what influence do audiences have on film and theatre performances? how do film and theatre actors influence audiences? in the musical scene with cosmo (starting at time code 27: 00), how does the actor use props? what is the result? do you think the use of props effectively fulfilled the artistic vision for this musical number? why or why not?
