Select the correct statement(s) regarding digital baseband modulation.
a. similar to analog signal modulation, logical ""1s"" and ""0s"" are represented by carrier wave amplitudes, frequencies, or phase angles
b. QAM is a modulation technique in which both carrier amplitude and phase angle changes represent logical data
c. with QAM, two carrier waves of the same frequency, but separated by π/2 radians, are used to represent logical data
d. all statements are correct
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 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
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.
The screenshot of output is attached.

What are the four components of the Universal Systems Model?
Answer:
output, process, input, and feedback
Explanation:
Write a short quiz program which asks three true/false questions and stores the user's answers as booleans. At the end the program it should print the user's answers with the correct answers.
Note: you should use the same quiz questions and correct answers as the sample run below.
Sample run:
Java is a programming language, true or false?
true
Only numbers can be stored by variables in Java, true or false?
true
There are only 2 possible values which can be held by a boolean variable, true or false?
false
Question 1 - Your answer: true. Correct answer: true
Question 2 - Your answer: true. Correct answer: false
Question 3 - Your answer: false. Correct
AP CS A Unit 1: Lesson 3 - Coding Activity 3
this answering question interface is bleh
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.

A program is written to compute the sum of the integers from 1 to 10. The programmer, well trained in reusability and maintainability, writes the program so that it computes the sum of the numbers from k to n. However, a team of security specialists scrutinizes the code. The team certifies that this program properly sets k to 1 and n to 10; therefore, the program is certified as being properly restricted in that it always operates on precisely the range 1 to 10.
Required:
List different ways that this program can be sabotaged so that during execution it computes a different sum, such as 3 to 20.
Answer:
See explanation
Explanation:
An instance of such program written in python is
isum = 0
for i in range(1,11):
isum = isum + i
print(sum)
One of the ways the program can give a wrong result is when someone alters the program source program before it's complied and executed.
Take for instance.
Changing
isum = 0 to isum = 4
will alter the result by additional 4
Another way is if an outside program or process alters the program execution.

Create a class named FormLetterWriter that includes two overloaded methods named displaySalutation(). The first method takes one String parameter that represents a customer's last name, it displays the salutation "Dear Mr. or Ms." followed by the last name. The second method accepts two String parameters that represent a first and last name, and it displays the greeting "Dear" followed by the first name, a space, and the last name. After each salutation, display the rest of a short business letter: "Thank you for your recent order." Write a main() method that tests each overloaded method. Save the file as FormLetterWriter.java.
Answer:
Follows are the code to this question:
public class FormLetterWriter//defining class
{
static void displaySalutation(String last_Name)//defining a method displaySalutation
{
System.out.println("Dear Mr. or Ms. " + last_Name);//print value
}
static void displaySalutation(String first_Name, String last_Name) //overload the method displaySalutation
{
System.out.println("Dear " + first_Name + " " + last_Name);//print value
}
public static void message()//defining a method message
{
System.out.println("Thank you for your recent order.");//print message
}
public static void main(String[] args) //defining main method
{
displaySalutation("I Kell");//calling a method displaySalutation by passing a single String value
message();//calling message method
displaySalutation("Christ", "John");//calling a method displaySalutation by passing a two String value
message();//calling message method
}
}

Explanation:
In the above given program a calss "FormLetterWriter" is defined, in side the class we perform the method overloading, in which a method "displaySalutation" is used in first definition it accepts a single string variable "first_Name", and in second time, it accept two string variable " first_Name and last_Name".
Inside the both method, we use print method, that print its value, and an onther method message is defined, that print the given message.
In the class main method is declared, in which we apply mathod overloading and also call the message method for print the given business letter.

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?
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.

HOPE THIS HELPED MAKE ME THE BRAINLIST!
Using programming concepts, the option that is NOT a reason to include comments in a code is:
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.A similar problem is given at https://brainly.com/question/13527834

Could someone explain a Boolean?
Answer:
It is a "True" or "False" integer.
Explanation:
denoting a system of algebraic notation used to represent logical propositions, especially in computing and electronics.
a binary variable, having two possible values called “true” and “false.”.
Answer:
Booleans are “truth values” — they are a data type that can contain either the value true or false. (These values may be represented as 1 or 0 in other programming languages!) Boolean statements are statements that evaluate to be true or false.
g Unlike when you create a String, when you create a StringBuilder, you must use the keyword ____________.
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.
