1.1.1(C): Show understanding of the concept of a byte and how the byte is used to measure the memory size

1 byte = 8 bits

1 kilobyte = 8 kilobits

1 megabyte = 8 megabits

e.g: The upload speed on the internet is 32 megabits per second. How long would it take a 40 megabyte file to upload?

First, convert the megabits into megabytes:

8 megabits = 1 megabyte    32 megabits = 4 megabytes

4 megabytes per second. 40 megabyte file. 40 / 4 = 10 seconds to transfer
