| **The data transfer rate over ADSL is 128000 bps connection. It took 16 seconds to transfer the file through this connection. Determine the file size in KB.**

Let’s determine what the volume of the file transferred using the ADSL connection, whose speed is 128000 bit / s, was, if from the condition of our problem we know for sure that this took 16 seconds:

128000 * 16 = 2048000.

Let’s determine how many kilobytes the volume will be equal to, which was calculated by us in the previous step:

1 byte is the same as 8 bits;

1 kilobyte is the same as 1024 bytes;

2048000: 8: 1024 = 250.

Answer: The size of the transferred file is 250 KB.
