1. What is the speed of the connection from your computer to the Sydney location on the map?
0.14 Mbps
2. Why did the data transfer rates vary? [Hint: think of what happens when an eight lane highway moves into a two lane highway?]
The data transfer rates vary because there is so much information trying to be transferred. But only a limited amount of room to do it in. At times it may be fast because there is nothing else that is being transferred, while other times it can take a long time because there are many things being transfer at the one time.
