Answer:

Thrashing :- It is a situation when the system most of it's time is handling page faults, but the actual work done by CPU is very less.

Thrashing is caused by when a process is allocated too few number of frames, then there will be continuous page faults.The actual Utilization of CPU is very less.

Thrashing detection can be done by the system by determining the CPU Utilization as compared to degree of multi programming if it comes out to be less then there is thrashing.

Thrashing can be eliminated by decreasing the Degree of multi programming.

Answer:

False: There are reasons to put comments in our code. We should have the habit of that.

Explanation:

Answer:

#include <iostream>

using namespace std;

int main()

{

   int years;

   cout<<"enter the number of years of school: ";

   cin>>years;

   cout<<"The educational level is: "<<years<<endl;

}

Explanation:

First include the library iostream in c++ program for input/output.

then create the main function and declare the variable.

after that, display the message by using cout instruction for asking the user to enter the value.

then, cin instruction store the value in the declare variable.

finally, display the message with corresponding value.

Final answer:

The provided Python program prompts for a score between 0.0 and 1.0, validates the input, and then outputs the corresponding grade or an error message if the input is not a number or out of range.

Explanation:

Here is a Python program that prompts for a score between 0.0 and 1.0, checks whether the score is in the valid range, and then prints the corresponding grade based on the score provided:

# Define named constants for grade thresholds
GRADE_A = 0.9
GRADE_B = 0.8
GRADE_C = 0.7
GRADE_D = 0.6
try:
   score = float(input('Enter a score between 0.0 and 1.0: '))
   if score < 0.0 or score > 1.0:
       print('Error: Score is out of range.')
   elif score >= GRADE_A:
       print('A')
   elif score >= GRADE_B:
       print('B')
   elif score >= GRADE_C:
       print('C')
   elif score >= GRADE_D:
       print('D')
   else:
       print('F')
except ValueError:
   print('Error: Please enter a numeric input.')
The program uses try and except blocks to handle non-numeric inputs gracefully, outputting an error message in such cases. Depending on the score entered by the user, the appropriate grade is printed using comparison operations against the named constants defining grade thresholds.
