Could someone explain a Boolean?

Answer:

this is AC b/c.... cos is a periodic function.. think waves... the voltage is going to vary between positive 5 and negative 5 volts... so it's a low voltage signal, but still AC,   the W is for how fast it's varying and the  +2 is the off set of the wave.  

Explanation:

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

Abstract

The purpose of this paper is to summarize the advantages of computers/software and the use of computer technology in investigations. Summarize the disadvantages to law enforcement with respect to the advancements of computers. Real cases will be researched in order to understand how computers can be utilized in criminal activities, as well as a case that the use of a computer was beneficial to the prosecution in a criminal case. A final conclusion paragraph will address my personal subjective opinion as to whether these technologies, in an overall sense are a benefit or hindrance to law enforcement efforts.

Introduction

Since computers have become such a big part of our…show more content…

From utilizing computers in cars so officers could run a license plate and social security number to see if there are any warrants out for the person they stopped, to more advances such as carrying cell phones, GPS tracking systems in cars, crime mapping tools, information sharing between state and local law enforcement, to even sharing information across countries. Technology has come a long way in helping officers and other agents within the criminal justice system do their job.  

Just a bit more about the advantages of the things mentioned above and time to move on. The most interesting thing is Geographic Information Systems (GIS), which has become a most important tool for law enforcement agencies. GIS, other mapping software and desktop computers now are capable of mapping and data analysis that is way above and beyond what used to be possible with backroom mainframe computers (Rubley, 2011).

Another great advancement is the widespread use of everyone using mobile devices. Many officers now use two to three cell phones.

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.

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.
