The applet below creates problems for you to practice computing performance-related quantities such as transfer rates, transfer times, data lengths and utilization. You will be given several such quantities, and asked to solve for a different one. When you have computed your answer, enter it in the box, click on the correct unit for your answer and then click on the "Check Answer" button to find out if you did the problem correctly. You may try the same problem with different numbers by clicking on the "Same Problem" button, or choose to practice calculating either the next variable in sequence ("Next Problem" button) or a random variable ("Random Problem" button).

All values are rounded to integers. For problems involving bus frequency, assume a serial bus. Also, you do need to choose the correct units to get the problem correct!
