horrorfan [7]

Answer:

//Define class

public class Main {

//define main method

public static void main(String[] args)

{

//declare and initialize the double type variable to 128

double mexico = 128;

//declare and initialize the double type variable to 323

double us = 323;

//declare and initialize the integer type variable to 0

int yr = 0;

//set the while loop to check which is greater

while (mexico < us)

{

//increment in the variable by 1

yr++;

//initialize in the variables acc. to the percentage

mexico *= 1.0101;

us *= 0.9985;

}

//print the following results

System.out.println("Population of the Mexico will be exceed the population U.S. in " + yr + " years");

System.out.println("Population of the Mexico will be " + mexico + " million");

System.out.println("and population of the U.S. will be " + us + " million");

}

}

<u>Output</u>:

Population of the Mexico will be exceed the population U.S. in81 years

Population of the Mexico will be 288.88435953355025 million

and population of the U.S. will be 286.0198193927948 million

Explanation:

<u>Following are the description of the program</u>.

Firstly, we define the class 'Main' and inside it, we define the main method.
Then, declare two double data type variables which are 'mexico' and 'us' and initialize in it to 128 and 323.
Declare integer data type variable 'yr' and initialize in it to 0.
Set the while loop and pass the condition to check that the variable 'mexico' is less than the variable 'us' then, increment in the variable 'yr' by 1 and multiply the variables 'us' and 'mexico' by the following percentage.
Finally, print the following results with the message.

Zarrin [17]

Answer:

see explaination please

Explanation:

a. Install a faster CPU. Answer:NO

Optional: a faster CPU reduces the CPU utilizationfurther since the CPU will spend more time waiting for a process toenter in the ready queue.

b. Install a bigger paging disk. Answer:NO

Optional: the size of the paging disk does not affect theamount of memory that is needed to reduce the pagefaults.

c. Increase the degree of multiprogramming Answer:NO

Since each process would have fewer frames available andthe page fault rate would increase

d. Decrease the degree of multiprogramming.Answer: YES

Optional: by suspending some of the processes, the otherprocesses will have more frames in order to bring their pages inthem, hence reducing the page faults.

e. Install more main memory. Answer:Likely

Optional: more pages can remain resident and do notrequire paging to or from the disks.

f. Install a faster hard disk or multiplecontrollers with multiple hard disks. Answer:Likely

(Optional)

g. Add prepaging to the page-fetchalgorithms.Answer: Likely

(Optional.)

h. Increase the page size. Answer:NO

Since each process would have fewer frames available and the page fault rate would increase
