The relationship among file size, transfer rate, and transfer time.
The data transfer rate (DTR) is the amount of digital data that is moved from one place to another in a given time. The data transfer rate can be viewed as the speed of travel of a given amount of data from one place to another. In general, the greater the bandwidth of a given path, the higher the data transfer rate. (Rouse, May 2011)
Have you made coffee before?
So latency is the time it takes you to get out the coffee, fill the pot with water, add a filter to the machine measure the coffee then pour the water
