Answer 1

Answer:

The answer is "Option d".

Explanation:

The electronic firmware synchronization was its method where even the series of bytes is amplified even before the transmission process into to the sound waves and, thus, and in conceptual "1s" and "0s" represented by large font, wavelengths, or switching frequency.

QAM utilizes both magnitudes of the transporter and adjustments in the phase shift. Rational data is represented by [tex]\frac{\pi}{2}[/tex] cartesian coordinates for both the carries waves of the same wavelengths and represents the result in total.

The concept of boolean variables is that; variables declared as boolean type can only take any of two values. The variable can either be true or false. Such variable cannot take any other value apart from these two.

The short quiz program is as follows.

Please note that comments are used to explain difficult lines.

import java.util.*;

public class shortQuiz{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

//This declares the variables that represent correct answers as boolean data type; the variables are also initialized

 boolean q1 = true, q2 = false, q3 = true;

//This declares the response to each question as boolean data type

 boolean q1response, q2response, q3response;

//This prints the first question

 System.out.print("Java is a programming language, true or false? ");

//This gets input for the first response

 q1response = input.nextBoolean();

//This prints the second question

 System.out.print("Only numbers can be stored by variables in Java, true or false? ");

//This gets input for the second response

 q2response = input.nextBoolean();

//This prints the third question

 System.out.print("There are only 2 possible values which can be held by a boolean variable, true or false? ");

//This gets input for the third response

 q3response = input.nextBoolean();

//This prints your first response, alongside the correct answer to the first question

 System.out.println("Question 1 - Your answer: "+q1response+". Correct answer: "+q1);

//This prints your second response, alongside the correct answer to the second question

 System.out.println("Question 2 - Your answer: "+q2response+". Correct answer: "+q2);

//This prints your third response, alongside the correct answer to the third question

 System.out.println("Question 3 - Your answer: "+q3response+". Correct answer: "+q3);

//The program ends here

}

}

See attached image for program sample run.

The above program initializes the correct answers using boolean variables. The correct answers are then printed, after the user answers the three questions.

g Unlike when you create a String, when you create a StringBuilder, you must use the keyword ____________.

Answers

Answer:

Unlike when you create a String, when you create a StringBuilder, you must use the keyword new

Explanation:

Strings are used in programming which also opens the way for StringBuilder to be used too. In javascript, for instance, variables are useful for storing data, We have "Let" and "const" variables. Const variables cannot be changed after they’re created. The data stored are in types an example is a string. Strings allow one to write a value and store the result in a variable.

For example, using the dot operator, when you:

console.log('love'.length); // Prints 4

Note that console.log()  allows the computer to evaluate the expression inside the parentheses and print that result to the console.

.length prints 4 as the result. This shows how the string has a property that stores the number of characters in that string.

StringBuilder with the keyword "new" is used when we want to change or modify data property stored in a string.

Scenario: You are part of an IT group managing Active Directory for a mid-size organization. A contracted research group with their own IT team operating from a remote location with a slow network connection has requested that they be able to setup a Child Domain in your organization's domain. The remote IT teams argument is based on their slow network, and their need to access and administer the local server that would need to exist in their remote location. Your team is split between allowing the Child Domain or recommending an Organizational Unit and delegating the remote IT team access. Yours is the deciding vote -- and cost is being considered a deciding factor. What option do you support as the best option in this scenario? What DC configuration for the remotely located server would be the best option?
If instead of cost, the deciding factor was the slow speed of their network, what option would you support as the best option?

Answers

Explanation:

1.

the answer to the first question is organizational unit. this is because in this scenario that we have before us, cost is a deciding factor. a unit as this can adapt to changes, it is flexible and also not very complex

2.

answer to question 2 is PDC emulator. this emulator can perform the function synchronization of time across every domain controller that is in the domain. other of its functions are, authentication and changing of passwords.

3.

the answer to the 3rd question is child domain. It is a factor in this scenario because it works well in a situation where there is an issue of slow network connection.

Answer: it gives address the time to get there the things they selll

Explanation:

The Goal: Similar to the first project, this project also uses the random module in Python. The program will first randomly generate a number unknown to the user. The user needs to guess what that number is. (In other words, the user needs to be able to input information.) If the user’s guess is wrong, the program should return some sort of indication as to how wrong (e.g. The number is too high or too low). If the user guesses correctly, a positive indication should appear. You’ll need functions to check if the user input is an actual number, to see the difference between the inputted number and the randomly generated numbers, and to then compare the numbers.• Concepts to keep in mind: • Random function• Variables• Integers• Input/Output• Print• While loops• If/Else statements

Answers

Answer:

Here is the Python program:

import random #to generate random numbers

def generateRandNo(): #function to generate random number

    randNo = random.randint(1,100) #generates random number in range from 1 to 100

    return randNo #returns the generated random number

   

def userInput(message = "Guess the number "): #to gets integer input from user and return the input number

    userGuess = int(input(message)) #store the int type input from user in userGuess variable

    return userGuess #returns the user input number

   

def compareNumbers(userGuess,randNo): #compares the user input with actual randomly generated number

    if userGuess > randNo: # if user input is greater than actual number

         return "The number is too high"

    elif userGuess < randNo: #if user input is less than actual number

         return "The number is too low"

    else: #if user guess is correct

         return "Correct"

def main(): #main method

    correct = False #sets correct to False

    begin = True #sets start game i.e. begin to True

    while correct or begin: #while loop keeps repeating as long as user guess is correct or user wants to start game again

         guessCount = 0  #counts number of trials user takes to guess the correct number

         randNo = generateRandNo() #generates a random number using generateRandNo

         userGuess = userInput() #gets input number from user using userInput method

         guessCount+=1 #increments at each guess made by user

         message = compareNumbers(userGuess,randNo) #compares user guess input number with actual number

         

         while message != "Correct" : # while message is not equal to Correct

              print(message) #prints to guess the number

              userGuess = userInput("Try again: ") #keeps asking user to try again and enter a number

              guessCount = guessCount + 1 #increments guessCount  by 1 at each guess made by user

              message = compareNumbers(userGuess,randNo) #compares user input with actual number

         print()

         print(message,"It took you ",guessCount," attempts to answer\n") #prints how much trials user took to guess correct number

         choice = input("Do you wish to continue? (Enter yes or no) ") #asks user if user wants to start over

         if choice == 'no': # if user enters no

              exit(1) #exits the program

         else: #if user enters yes starts the game again

              correct = True #sets correct guess to True

main() #calls main method to start the guess game

Explanation:

The program is well explained in the comments attached with each line of the code. Suppose the randomly generated number (actual number) is 50 and user input is 24  then message The number is too low is displayed and if user guess input is 80 then The number is too high is displayed. If the user guesses the correct number i.e. 50 3rd time then the message displayed is:

It took you 3 attempts to answer.

The the user is asked to continue as:

Do you wish to continue? (Enter yes or no)

If user enters no the program exits if yes then user is asked to Guess the number again.

a. Comments help the computer decide whether certain components of a program  are important.

-------------------------

Usually, codes are very long, and each person is responsible for a part of the problem. The parts have to be intervened with each other, and thus, sometimes a programmer will have to look at another part of the code, not coded by him. Thus, for the programmer and other people working in the project to understand, comments are important.Additionally, the comments are used to help the programmers debug their own code, as they can go part by part and see what is done in each part, also helping them work throughout the development process.In a program, there may be some components that end up not being necessary, but this is not decided by comments, and thus, option A is not a reason to include comments in programs.
