A particular system is controlled b

A particular system is controlled by an operator through commands entered from a
keyboard. The average number of commands entered in an 8-hour interval is 60.
a. Suppose the processor scans the keyboard every 100 ms. How many times will the
keyboard be checked in an 8-hour period?
b. By what fraction would the number of processor visits to the keyboard be reduced
if interrupt-driven I/O were used?Only 60 visits would be required. The reduction is 1 – (60/288000) = 0.999, or
