Answer:

The correct answer is 1,480 Mbps.

Explanation:

For this you have to know how to convert bytes to different units.

1,000 Bytes (b)  = 1 Kilobyte (Kb)

1,000 Kilobyte (Kb) = 1 Megabyte (Mb)

1,000 Megabytes (Mb) = 1 Gigabyte (Gb)

and Finally, 1,000 Gigabytes (Gb) = 1 Terrabyte (Tb)

Answer:

1,480 Mbps

Explanation:

1,480 Mbps is equal to 1.48 Gbps, and so it is the fastest transfer rate listed because it is greater than 1.24 Gbps. In summary, 1,480 Mbps > 1.24 Gbps > 181 Mbps > 1,282 Kbps.

Answer:

D. Division by zero.

Explanation:

This Java code that is being provided in the question will output the following error.

Division by zero

This is because the main method is calling the division method and passing 0 for the variable b. The method detects this with the if statement and creates a new Exception. This exception is grabbed by the catch(Exception exception) line and prints out the error Division by zero.

Answer:

Explanation:

The following procedure is written in Python. It takes the next argument, checks if it is an odd number and if so it adds it to oddsum. Then it asks the user for a new number from the keyboard and calls the accumulator procedure/function again using that number. If any even number is passed the function terminates and returns the value of oddsum.

def accumulator(next, oddsum = 0):

   if (next % 2) != 0:

       oddsum += next

       newNext = int(input("Enter new number: "))

       return accumulator(newNext, oddsum)

   else:

       return oddsum

Answer:

Explanation:

The following method will take in a LinkedList as an argument and split it, adding only the first element to the firstItemList and the rest of the elements to listRemainder. The firstItemList and ListRemainder may have to be changed to static in order for the method to be able to access them, or add a setter/getter method for them.

public static void split(LinkedList list) {

       firstItemList = new LinkedList();

       listRemainder = new LinkedList();

       firstItemList.add(list.peek());

       list.pop();

       listRemainder = list;

       }

The complete java code for the Runner class can be defined as follows:

public class Runner<T>//defining a class Runner

{

   private LinkedList<T> firstItemList;//defining LinkedList type array variable that is firstItemList

   private LinkedList<T> ListRemainder;//defining LinkedList type array variable that is ListRemainder

   public Runner()//defining default constructor

   {

       firstItemList=null;//holding null value in list type variable

       ListRemainder=null;//holding null value in list type variable

   }

   public void split(LinkedList<T> WholeLinkedList)//defining a method split that takes a list in parameter

   {

       if(WholeLinkedList==null)//defining if block that checks parameter variable value equal to null

           return;//using return keyword

       firstItemList=WholeLinkedList;//holding parameter variable value in firstItemList

       ListRemainder=WholeLinkedList.next;//holding parameter variable next value in ListRemainder

       firstItemList.next=null;//holding null value in firstItemList.next element

   }

}

Answer:

B. To continuously check the state of a condition.

Explanation:

The purpose of an infinite loop with an "if" statement is to constantly check if that condition is true or false. Once it meets the conditions of the "if" statement, the "if" statement will execute whatever code is inside of it.

Example:

//This pseudocode will print "i is even!" every time i is an even number

int i = 0;

while (1 != 0)       //always evaluates to true, meaning it loops forever

  i = i + 1;               // i gets incrementally bigger with each loop

     if ( i % 2 == 0)     //if i is even....

               say ("i is even!"); //print this statement

A good starting point is by addressing some of the key reasons software projects fail.

Explanation:

Not Enough Time. ...

Insufficient Budget. ...

Poor Communication. ...

Never Reviewing Project Progress. ...

Inadequate Testing. ...

Testing in the Production Environment. ...

Lack of Quality Assurance. ...

Not Conforming to Industry Standards.

User involvement, management support, reasonable requirements, and accurate projections are some of the most frequent aspects that contribute to software project success.

A software project is the entire process of developing software, from gathering requirements to testing and maintenance, carried out in accordance with execution techniques over a predetermined amount of time to produce the desired software output.

Some of the most frequent factors that influence the success of software projects are user interaction, management support, fair needs, and realistic estimates.

Application bug or error, environmental conditions, infrastructure or software failure, virus, hacker, network/hardware failure, and operator error are the main causes of software project failure.

According to the study, project success and failure are most heavily influenced by the degree of customer/user interaction, software process management, and estimation and timeline.

Thus, these are the reasons of a successful and unsuccessful software project.

Answer:

The main problem with such a tool would be resource usage

Explanation:

The main problem with such a tool would be resource usage. Such a tool would need a large amount of CPU power in order to check all of the files on the system thoroughly and at a fast enough speed to finish the process before the next cycle starts. Such a program would also have to allocate a large amount of hard drive space since it would need to temporarily save the original versions of these files in order to compare the current file to the original version and determine whether it changed or not. Depending the amount of files in the system the work on configuring the program may be very extensive since each individual file needs to be analyzed to determine whether or not they need to be verified by the program or not. Monitoring responses may not be so time consuming since the program should only warn about changes that have occurred which may be only 10% of the files on a daily basis or less.

Explanation:

The following code is written in Java, it prompts the user to enter 10 integers and saves them to an ArrayList. Then it prompts for 5 strings and saves them to another ArrayList. Then, it calls the sort method and adds the lists as parameters. Finally, it prints out both lists completely sorted in ascending order.

import java.util.ArrayList;

import java.util.Scanner;

class Division{

   public static double division(double a, double b) throws Exception {

       if(b == 0)

       ArrayList<Integer> mylist2 = new ArrayList<>();

       for (int x = 0; x < 10; x++) {

Design patterns help you write code faster by providing a clear idea of how to implement the design

Explanation:

Design patterns help you write code faster by providing a clear idea of how to implement the design. These are basically patterns that have already be implemented by millions of dev teams all over the world and have been tested as efficient solutions to problems that tend to appear often. Using these allows you to simply focus on writing the code instead of having to spend time thinking about the problem and develop a solution. Instead, you simply follow the already developed design pattern and write the code to solve that problem that the design solves.

Answer:

The program is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

 String score;

 System.out.print("Scores: ");

 score = input.nextLine();

 String[] scores_string = score.split(" ");

 double total = 0;

 for(int i = 0; i<scores_string.length;i++){

     total+= Double.parseDouble(scores_string[i]);  }

 double average = total/scores_string.length;

 System.out.format("Average: %.3f", average); }

}

Explanation:

This declares score as string

 String score;

This prompts the user for scores

 System.out.print("Scores: ");

This gets the input from the user

 score = input.nextLine();

This splits the scores into an array

 String[] scores_string = score.split(" ");

This initializes total to 0

 double total = 0;

This iterates through the scores

 for(int i = 0; i<scores_string.length;i++){

This calculates the sum by first converting each entry to double

     total+= Double.parseDouble(scores_string[i]);  }

The average is calculated here

 double average = total/scores_string.length;

This prints the average

 System.out.format("Average: %.3f", average); }

}
