Explanation:

CARRIER ETHERNET can be defined as the Ethernet which is a telecommunications network providers that provides and enables all Ethernet services to their customers and as well to help them utilize the Ethernet technology in their networks which is why the word “Carrier” in Carrier Ethernet networks is tend to refers to a large communications services providers that has a very wide reach through all their global networks. Example of the carriers are:

They help to provide audio, video, as well as data services to residential and to all business as well as enterprise customers.

CARRIER ETHERNET also make use of high-bandwidth Ethernet technology for easy Internet access and as well as for communication among the end users.

Therefore all the statement about CARRIER ETHERNET NETWORK are correct

a. Metro Ethernet Forum (MEF) is a type of ethernet which created a Carrier Ethernet framework in order to ensure the interoperability of service provider that the Carrier Ethernet is offerings.

b. The MEF also help to certifies CE network providers, as well as the manufacturers and network professionals in order to ensure interoperability as well as a great service competencies.

c. MEF certified services also include E-Line, E-LAN, E-Tree, E-Access, and E-Transit

Hence, MEF is an important part of Carrier Ethernet because they act as the defining body for them, reason been that they are as well telecommunications service providers, cable MSOs, as well as network equipment and software manufacturers among others.

Explanation:

Answer:

I am writing a JAVA program. Let me know if you want the program in some other programming language.

public class FourthRoot{ //class to calculate fourth root of 81

public static void main(String[] args) { //start of main() function body

   double square_root; //declares to hold the fourth root of 81

   double number=81; // number is assigned the value 81

/* calculates the fourth root of number using sqrt() method twice which means sqrt() of sqrt(). This is equivalent to pow(number,(0.25)) where pow is power function that computes the fourth root by raising the number 81 to the power of 0.25 which is 1/4 */

   square_root=Math.sqrt(Math.sqrt(number));

//displays the fourth root of 81 i.e. 3

     System.out.println("Fourth Root of 81 is "+ square_root); } }

Explanation:

The program is well explained in the comments given along with each statement of the program . Since it was the requirement of the program to user Math.sqrt() method so the fourth root of number= 81 is computed by taking the sqrt() of 81 twice which results in the fourth root of 81 which is 3.

So the first sqrt(81) is 9 and then the sqrt() of the result is taken again to get the fourth root of 81. So sqrt(9) gives 3. So the result of these two computations is stored in square_root variable and the last print statement displays this value of square_root i.e. the fourth root of number=81 which is 3.

Another way to implement the program is to first take sqrt(81) and store the result in a variable i.e. square_root. After this, again take the sqrt() of the result previously computed and display the final result.

public class FourthRoot{

   public static void main(String[] args) {

   double square_root;

   double number=81;

   square_root=Math.sqrt(number);

  System.out.println("Fourth Root of 81 is: "+ Math.sqrt(square_root)); } }

//method listUpper takes a list of strings as parameter

public List<String> listUpper(List<String> list)

{ List<String> finalList= new ArrayList<String>();

//finalList is created which is a list to display the strings in upper case

for(String s:list){ //loop iterates through every string in the list and converts each string to Upper case using toUpperCase() method

s = s.toUpperCase();

finalList.add(s); } //finally the upper case strings are added to the finalList

return finalList; } //return the final list with uppercase strings

Explanation:

The method listUpper() works as follows:

For example we have a list of following strings: ("a", "an", "being").

finalList is a list created which will contains the above strings after converting them to uppercase letters.

For loop moves through each string in the list with these strings ("a", "an", "being"). At each iteration it converts each string in the list to uppercase using toUpperCase() and then add the string after converting to uppercase form to the finalList using add() method. So at first iteration "a" is converted to A and added to finalList, then "an" is converted to uppercase AN and added to finalList and at last iteration "being" is converted to BEING and added to finalList. At the end return statement returns the finalList which now contains all the string from list in uppercase form.

The method called listUpper() that takes in a list of strings, and returns a list of the same length containing the same strings but in all uppercase form is as follows:

def listUpper(list_string):

    for i in range(len(list_string)):

         list_string[i] = list_string[i].upper()

    return list_string

print(listUpper(["buy", "dog", "rice", "brought", "gun"]))

Here is the JAVA program to calculate volume of cuboid:

import java.util.Scanner; // Scanner class is used to take input from user

public class CuboidVol { // class to calculate volume of cuboid

public static void main(String[] args) { // start of main() function body

Scanner input= new Scanner(System.in); //create Scanner class object

// prompts user to enter length of cuboid

System.out.println("Enter the cuboid length:");

double length=input.nextDouble(); //reads the input length value from user

// prompts user to enter width of cuboid

System.out.println("Enter the cuboid width:");

double width=input.nextDouble(); //reads the input width from user

// prompts user to enter height of cuboid

System.out.println("Enter the cuboid height:");

double height=input.nextDouble(); //reads the input height from user

/* the following formula is to calculate volume of a cuboid by multiplying its length width and height and a double type variable cuboidVolume is defined to store the value of the resultant volume to it */

double  cuboidVolume= length*width*height; //calculates cuboid volume

//displays volume of cuboid and result is displayed up to 2 decimal places

System.out.printf("Volume of the cuboid (length " + length + "/ height " + height + "/ width" +width +" is: " + "%.2f",cuboidVolume);   } }

Explanation:

The formula for the volume of a cuboid is as following:

Volume = Length × Width ×  Height

So in order to calculate the volume of cuboid three variable are required for length, width and height and one more variable cuboidVolume to hold the resultant volume of the cuboid.

The program is well explained in the comments added to each statement of the program. The program prompts the user to enter the value of height width and length of cuboid and the nextDouble() method is used to take the double type input values of height length and width. Then the program declares a double type variable cuboidVolume to hold the result of the volume of cuboid. Then the last printf statement is used to display the volume of cuboid in the format format "Volume of the cuboid (length  / height  / width ) is" and the result is displayed up to 2 decimal places.

if inp.upper() == letterg[i]:

print('The numeric value for grade ', inp, ' is ',4 - i)

else:

print(inp, "is an invalid grade")

Explanation:

This line initializes all letter grade from A to F

letterg = ['A','B','C','D','F']

This line prompts user for letter grade

inp = input("Enter a Letter Grade: ")

This line iterates through the initialized letter grades

for i in range(len(letterg)):

This line checks if the user input is present in the initialized letter grades (it also takes care of lowercase letters)

if inp.upper() == letterg[i]:

This line is executed if tge about condition is true; the line calculates the number grade and prints it

print('The numeric value for grade ', inp, ' is ',4 - i)

Here is a UpdateTimeWindow() method with parameters timeStart, timeEnd, and offsetAmount

// the timeEnd and timeStart variables are passed by pointer

void UpdateTimeWindow(int* timeStart, int* timeEnd, int offsetAmount){

// this can also be written as  *timeStart = *timeStart + offsetAmount;

*timeStart += offsetAmount;  //adds value of offsetAmount to that of //timeStart

// this can also be written as  *timeEnd = *timeEnd + offsetAmount;

  *timeEnd += offsetAmount;  } //adds value of offsetAmount to that of //timeEnd

Explanation:

The function has three int parameters timeStart, timeEnd, and offsetAmount.

First two parameters timeStart and End are passed by pointer. You can see the asterisk sign with them. Then in the body of the function there are two statements *timeStart += offsetAmount; and *End+= offsetAmount; in these statements the offsetAmount is added to the each of the two parameters timeStart and timeEnd.

Answer:

import random

guess = int(input("Make a guess: "))

total = count = 0

while total < 100:

   roll = random.randint(1, 6)

   total += roll

   count += 1

if guess == count:

   print("Your guess is correct")

elif guess > count:

   print("Your guess is high")

else:

   print("Your guess is low")

Explanation:

*The code is in Python.

Import the random module to simulate the dice roll

Ask the user to make a guess

Initialize the total and count as 0

Create a while loop that iterates while the total is smaller than 100. Inside the loop, use random to get a random number between 1 and 6 and set it to the roll. Add the roll to the total. Increment the count by 1.

When the loop is done, check the guess and count. If they are equal, that means the guess is correct. If the guess is greater than the count, that means it is high. If the previous cases are not true, then the guess is low.

Here is the sentinel-controlled while loop:

#include <iostream> //to use input output functions

using namespace std; // to identify objects like cin cout

int main(){ // start of main() function body

int test_score; // declare an integer variable for test scores

//prompts user to enter test scores and type-99 to stop entering scores

cout << "Enter the test scores (enter -99 to stop): ";

cin >> test_score; // reads test scores from user

while (test_score != -99){ // while loop keeps executing until user enters -99

cin >> test_score; } } // keeps taking and reading test scores from user

Explanation:

while loop in the above chunk of code keeps taking input scores from user until -99 is entered. Sentinel-controlled loops keep repeating until a sentinel value is entered. This sentinel value indicates the end of the data entry such as here the sentinel value is -99 which stops the while loop from iterating and taking the test score input from user.

The complete question is that the code should then report how many scores were  entered and the average of these scores. Do not count the end sentinel -99 as a score.

So the program that takes input scores and computes the number of scores entered and average of these scores is given below.

#include <iostream>  // to use input output functions

using namespace std;  // to identify objects like cin cout

int main(){  //start of main function body

double sum = 0.0;  // declares sum variable to hold the sum of test scores

int test_score,count =0;  

/* declares test_scores variable to hold the test scores entered by user and count variable to count how many test scores input by user */

cout << "Enter the test scores (or -99 to stop: ";

//prompts user to enter test scores and type-99 to stop entering scores

cin >> test_score;  // reads test scores from user

while (test_score != -99){  // while loop keeps executing until user enters -99

count++;  /* increments count variable each time a test cores is input by user to count the number of times user entered test scores */

sum = sum + test_score;  // adds the test scores

cin >> test_score;}  // reads test scores from user

if (count == 0)  // if user enters no test score displays the following message

cout << "No score entered by the user" << endl;

else  //if user enters test scores

//displays the numbers of times test scores are entered by user

cout<<"The number of test scores entered: "<<count;

/* displays average of test scores by dividing the sum of input test scores with the total number of input test scores */

cout << "\n The average of " << count << " test scores: " <<sum / count << endl;}

Answer:

xyz = 25  

result = square(xyz)

print(result)

The above code assigns the value 25 to variable xyz as 5*5=25. Then next statement is a function call to square() function passing xyz to this function in order to compute the square of 25. The output is:

625

Explanation:

The above code can also be written as:

xyz = 5*5

result = square(xyz)

print(result)

The difference is that xyz is assiged 5*5 which is equal to 25 so the output produced will be the same i.e.  625.

The result variable is used to store the value of square of 25 after the square() method computes and returns the square of 25. So print(result) prints the resultant value stored in the result variable i.e. 625
