Unit 2 Assignment 1: Transfer Time

File Size | Transfer Rate | Transfer Time | 100 MB | 56 Kbps | 15 seconds | 100 MB | 4 Mbps | .2 seconds | 2 GB | 56 Kbps | 4 minutes 46 seconds | 2 GB | 4 Mbps | 4 seconds |

(100 MB x 1,000 x 8) / (56 Kbps x 1000) = 15 seconds
(100 MB x 1,000 x 8) / (4 Mbps x 1,000 x 1,000) = .2 seconds
(2 GB x 1,000 x 1,000 x 8) / (56 Kbps x 1,000) = 286 seconds = 4 minutes 46 seconds
(2 GB x 1,000 x 1,000 x 8) / (4 Mbps x 1000 x 1,000) = 4 seconds

Transfer Rate | Transfer Time | File Size | 56 Kbps | 30 minutes | 12.6 MB | 4 Mbps | 10 minutes | 300 MB | 56 Kbps | 4 hours | 100.8 MB | 4 Mbps | 2 hours | 3.6 GB |

(30 min. x 60 sec.) x (56 Kbps x 1000) = 100,800,000 b
(100,800,000 b / 8) / 1000 = 12,600 KB = 12.6 MB

(10 min. x 60 sec.) x (4 Mbps x 1000 x 1,000) = 2,400,000,000 b
(2,400,000,000 b / 8) / 1000 = 300,000 KB = 300 MB

(4 hrs. x 60 min. x 60 sec.) x (56 Kbps x 1000) = 806,400,000 b
(806,400,000 b / 8) / 1000 = 100,800 KB = 100.8 MB

(2 hrs. x 60 min. x 60 sec.) x (4 Mbps x 1000 x 1,000) = 28,800,000,000 b
(28,800,000,000 b / 8) / 1000 = 3,600,000 KB = 3,600 MB = 3.6 GB

A file can only transfer as fast as the transfer rate will allow. How long it takes to transfer a single file depends on how big the file is and how fast the transfer rate is. Everything depends on the other.

All rights reserved. Dr. Anne-Wil Harzing University of Melbourne Department of Management Faculty of Economics & Commerce Parkville Campus Melbourne, VIC 3010 Australia Email: Web: Balancing Global and Local Strategic Contexts: Expatriate Knowledge Transfer, Applications and Learning within a Transnational Organization Abstract In this paper we investigate how expatriates contribute to the transnational firm’s strategic objectives of global efficiency, national (‘local’) responsiveness, and worldwide learning. We focus on their knowledge applications and experiential learning, two assignment-based outcomes of potential strategic value to the firm. We assess how these outcomes are impacted by the expatriate’s everyday knowledge access and communication activities, measured by their frequency and geographic extent. Within our case organization, a prototype transnational firm, we find that the expatriates’ knowledge applications result from their frequent knowledge access and communication with the corporate headquarters and other global units of the firm. In contrast, their experiential learning derives......

They also take pride in their equipment so they are willing to spend more money on these items. Author: An author would need something portable to go anywhere they would want to go and still be able to write. They also wouldn’t need a very strong PC since they are just using it to write and not running any intense programs. They would most likely use either of the laptops listed above to do so. Doctor: A doctor would use a desktop like the gamer, but they wouldn’t need the computing power because they are not running any intense software similar to the author. They would need extra space to keep patient data if need be so they would need a large HDD. Most likely going with the HP Pavilion. Teacher: A teacher would more than likely have both of these types of computers but I would see a laptop being much more convenient. Being able to bring all of their grades around from classroom to classroom without bringing an entire desktop with them would be a life......

(Multiply by 1024 to get to GB -> MB -> KB -> bytes). 2 GB x 1024 = 2048 MB= 2048 * 1024 = 2097152 KB= 2097152 * 1024 = 2147483648 bytesStep 2: Covert file size from bytes to bits. (Multiply by 8).2147483648 * 8 = 17,179,869,184 bitsYou can combine Steps 1 and 2 by doing it in one step: 2 * 1024 * 1024 * 1024 * 8 (will give file size in bits)Step 3: Covert transfer rate to bits per sec. (Multiply by 1000).56 Kbps * 1000 = 56,000 bpsStep 4: Divide Step 2 result by Step 3 result to get transfer time in seconds.17,179,869,184 / 56,000 = 306,783.3783 secondsStep 5: Convert Step 4 answer in seconds to minutes, hours, days etc.306,783.3783 seconds / 60 = 5113 minutes (Divide by 60 to convert secs to mins)= 5113 minutes / 60 = 85.22 hours (Divide by 60 to convert mins to hours)= 85.22 hours /......

...David Durniok Assignment 2 Transfer Time 1. Fill in the Transfer Time column in Table 1. State all times in appropriate units (seconds, minutes, or hours). Show all your calculations and number conversions. File Size | Transfer Rate | Transfer Time | 100 MB | 56 Kbps | 5 hrs | 100 MB | 4 Mbps | 3.3 minutes | 2 GB | 56 Kbps | 83.22 hours | 2 GB | 4 Mbps | 1 hr, 8 mins, 16 seconds | * Take the 56kbps = 56,000 BITS per second, divide by 10 and you get 5,600 bytes. 100,000,000 / 5,600 = 17,857 seconds = 297.6 minutes = 4.96 hrs (almost 5 hrs) if there is no interruption in the transmittal. * 4Mbps (megabits) equals to approximately 500KB/s (kilobytes). 100MB (Mega Bytes) equals approximately 100000 KB  So assuming you can have a perfect transfer rate of 500KB/sec (assuming there is no TCP/IP overhead) you divide 100000KB by your 500KB/Sec transfer rate: 100000  /5000 = 200 seconds 200 seconds divided by 60 = 3.3 minutes. * 2GB * 1024MB/GB = 2048MB 2048MB * 1024KB/MB = 2097152 KB 2097152KB * 8Kb/KB = 16777216 Kb 16777216Kb / 56Kb/s = 299593s 299593s / 3600s/h = 83.22h so, at the theoretical rate of 56Kb/s, it would take 83.22 hours do download a 2GB file. At a more realistic average download rate of 4Kb/s, it would take 322.88 hours or just under two weeks to download. * 4 Mbps = 0.5 MB/s  The transfer rate is 0.5 MB/s  2048 / 0.5 = 4096 seconds  Time taken = 1 hour 8 minutes 16 seconds  2.

Recall that: · So we find: cos 2 We use u-v substitution (u=e-st, dv=cos(2t)) and get: sin 2 2 This does not give us a useful answer, so we perform a u-v substitution to the right hand side of the equation to obtain: cos 2 By rearranging the terms, we obtain: 4 4 cos 2 cos 2 cos 2 4 Next, we take the derivative of this expression with respect to s to obtain: 4 · cos 2 4 Finally, we put the terms together to obtain: 3 4 3 · cos 2 4 cos 2 Problem......
