Answer:
(a) Q = (M-(1-n)S)/n
(b)
When M = 450,
Q = 82
% CPU time wasted = 8.889%
When M = 90,
Q = 10
% CPU time wasted = 44.44%
When M = 50,
Q = 2
% CPU time wasted = 80%
Explanation:
Given Data:
n = process
T = ms time
Context switch time overhead = S
and M is total overhead
See attached file for the calculation.
The program is an illustration of if conditional statement. The programming language is not stated; so, I will answer the question using Python.
The program in Python where comments are used to explain each line is as follows:
<em>#This initializes the scores</em>
scores = ["Eagle","Birdle","Par","Bogey"]
<em>#This gets input for par</em>
par = int(input())
<em>#This gets input for stroke</em>
stroke = int(input())
<em>#This checks if par and stroke are between 3 and 5 (inclusive)</em>
if (par >=3 and par <= 5) or (stroke >=3 and stroke <= 5):
<em>#This calculates the difference between par and stroke</em>
diff = stroke - par + 2
<em>#This prints the corresponding score</em>
print(scores[diff])
<em>#If par or stroke is out of range of 3 and 5</em>
else:
<em>#This prints error</em>
print("Error")
<em>#At the end of the program, the appropriate score is printed.</em>
