Network Speed Measurements Homework

Use the same computer, same speed and method to access the network.

1. Look up the speed of your active network connection.

Speed:

2. Is this a raw bit rate or a net bit rate? motivate your answer.

3. Does the operating system give the correct abbreviation (b vs. B, Gvs. Gi)?

4. Use the bit rate as measured and convert it to KiBps. What is the maximum theoretical throughput?

5. Locate the Kali Linux .iso file. Copy it to your desktop and measure the time this takes.

6. Is this a measurement of throughput, or is it something else?

7. Delete the file and repeat the measurement two times:

i) Time for second measurement:

ii) Time for third measurement:

8. Calculate average and standard deviation of the three measurements.

9. Calculate the percentage of the theoretical maximum as determined in Question 4. Percentages of maximum theoretical throughput achieved:

10. Evaluate the result. Give two reasons for the difference, one theoretical reason and one practical one. Motivate the theoretical reason with a proper reference to a reliable source. Motivate the practical reason with empirical proof

Theoretical reason:

Reference:

Practical reason:

Proof:
