Use the bits per day calculated in question 2 and assume that the V.34 modems transmit at an average rate of 28,800 bps.City (a)Bits/ day a/ (28800x60)(b) MinutesAtlanta 63,150,000a/ (28800x60)36.55Chicago37,800,000a/ (28800x60)21.88Dallas73,500,000a/ (28800x60)42.53Denver17,250,000a/ (28800x60)9.98Houston30,150,000a/ (28800x60)17.45Jackson21,900,000a/ (28800x60)12.67Jacksonville21,150,000a/ (28800x60)12.24LA 11,550,000a/ (28800x60)6.68Memphis28,050,000a/ (28800x60)16.23Miami42,150,000a/ (28800x60)24.39Montgomery 6,750,000a/ (28800x60)3.91New Orleans 31,800,000a/ (28800x60)18.40Orlando 41,250,000a/ (28800x60)23.87St. Louise 14,850,000a/ (28800x60)8.59Tampa 47,850,000a/ (28800x60)27.69Washington7,350,000a/ (28800x60)4.25c.Previously, you calculated the transmission time in minutes per day, based on a 28,800-bps modem and 10 bits per character. Now calculate the file transfer time for Atlanta to transfer all of its invoices to Tampa at the end of the workday. Why is the answer different from the time calculated for Atlanta previously. -4210 packages x 750 x 10= 31,575,000/28800= 1096.35/60 seconds= 18.27. -This is basically half of 36.55 that we got earlier because we did not multiply by 2. (Sincewe are not going back and forth from origin to destination twice). d.Could all the NDAS offices transmit their invoices to Tampa between 5:00pm and 6:00pm each evening? How would they achieve this goal? -It is highly doubtful that these could be done considering we don’t know at which rate themodem would be working. 4.Would it be better to transmit all invoice information from the origin to Tampa and for Tampato send the information to the destination? Why?5.With the addition of a network that can handle voice, video, and data, what other uses and benefits can NDAS derive from the new network?
-So many more! Examples include videoconferencing (something the president showed great interest in before), teleconferencing, and live training!
