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:
sectors
Explanation:
hard disk contain tracks which are further divided into sectors, for storage purposes.
The informal answer to your question is "clipboard". However, there isn't such a thing as the "clipboard". The people who came up with the idea of the clipboard use that nomenclature to describe the location in memory where that copied data resides. So the formal answer to your question is memory or RAM.
I'd go for (C) similarly but not exactly sizedBasically, to explain an orifice tube in Layman’s context, it
is a car’s air conditioning system and is the exact place where the cold
happens. Not all orifice tubes are standard sized and this means that different
model vehicles use different sizes. These tubes are often color-coded for easy
identification.
