the computer's ability to process information at high speed means that when we request information ,we get a response very quickly,often in less that a second. using the computer to grade a quiz would get the results back to you more rapidly and save your teacher's time since there would be no tests to grade by hand. the implication of the computer's quick feedback are obvious. if fast answers help us to learn better,then the nearly instantaneous answers that we get from the computer can be of great help in our education.
