Explanation:
Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 = 1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec
Answer:
a. Power cycle the printer.
Explanation:
Power Cycle: To unplug the printer and restart it, is called power cycling. The peripheral devices often tend to stop working and the cause of this is not always easily figured out. So the first and easiest way that can be done to fix this issue is to run a power cycle. For this, you have to turn off the printer and unplug it. Then wait for a few seconds (at least 30) and plug in the printer again. Turn the printer on. Power cycle helps to resolve many basic issues. It is the easiest step to take before checking the printer cable, reinstalling printer or resetting the print spooler.
