Answer:
c. Buffer overflow
Explanation:
In Computer programming, buffer can be defined as an area of memory set aside specially and specifically for holding data or informations.
A type of exploit that relies on overwriting contents of memory to cause unpredictable results in an application is known as buffer overflow. This ultimately implies that, buffer overflow is the process of exceeding the storage capacity of a memory buffer with data, beyond the amount it is designed to hold and therefore overwrites any adjacent memory locations.
Buffer overflow attacks are becoming less common in modern operating systems because the modern operating system usually leaves a space between buffers and randomize the layout of memory through call mapping, as well as through the use of runtime protection.

How is a Creative Commons license different from a regular copyright? As a reminder, in the warm-up we saw the this scenario: ----------------------------------------------------------------------------------------------------------------------- Imagine you were using some of our pixelation tools to create an image and you posted it online for your friends to see - but, a week later you find out someone took that image and put it on a T-shirt that they’re selling for $10 each. -------------------------------------------------------------------------------------------------------------------- Now that we understand Copyright, what would need to change in order for the scenario from the warm-up to be okay?
Explanation:
You need to change the whole thing and do it differently.. And register it.
The thing that'll need to be changed in order for the scenario from the warm-up to be okay is to create a creative common license which will give room for people to be able to use my work and sell items that have my work on them.
In this case, the creative commons license enables one to share copyrighted work easily. It should be noted that intense protections are put on a work when the work is copyrighted. With the creative common, a person can allow others use their work as long as the person abide to rules.In conclusion, creative common allows one have control of one's work.

Ship contains a public method called getBearing() that consults gyroscopes and a compass to determine the direction in which the ship is moving and returns a Location object. You need to refactor the code to use a GPS receiver instead. You should
Answer:
Research of the GPS features and the modules and packages needed by the programming language to implement and receive data from a GPS tracker.
Explanation:
The Ship class is a blueprint that holds a data structure of a ship's location in coordinates. The location variable can be changed using the getBearing method and an instance of the ship class can be made several times for different ships in the harbor. This class depicts the power of object-oriented programming.
Refactoring is a concept in software engineering where source codes are modified to achieve code efficiency and speed. All programming language source code should be refactored where needed with the right packages or modules.
Which of the following is used to encrypt web application data?
a. MD5
b. AES
c. SHA
d. DHA
Answer:
b. AES
Explanation:
AES is an acronym for Advanced Encryption Standard and it is a cryptographic or symmetric block cipher that is based on a substitution-permutation network (SPN) used for the encryption of sensitive data over the internet or web. AES uses a key length of 128, 192 or 256 bits and a block length of 128 bits to encrypt data on web applications.
It is an encryption standard of the government of the United States of America and is supported by the National Institute of Standards and Technology (NIST).
Hence, AES is used to encrypt web application data and it uses an algorithm developed by Vincent Rijmen and Joan Daemen, known as the Rijndael algorithm.
write a program that first asks the user to enter three real numbers using GUI input. Print the sum if all three numbers are positive, print the product of the two positive numbers if only one is negative - use a nested if. Then, ask the user to enter two real numbers from the console. If both numbers are negative, print the quotient.
Answer:
Here is the complete program:
import javax.swing.JOptionPane; //to use GUI in JAVA application
import java.util.Scanner; //to take input from user at console
public class Main {
public static void main(String[] args) { //start of main function body
String num1, num2,num3; //declare three variables to store strings of numbers for input dialog
double number1, number2, number3, sum,product; //declare three double type variables to hold the real numbers
num1 = JOptionPane.showInputDialog("num1"); //shows a dialog box prompting user to enter value of first number i.e. num1
number1 = Double.parseDouble(num1); //scans and reads the value of first input number i.e. number1
num2 = JOptionPane.showInputDialog("num2"); //shows a dialog box prompting user to enter value of second number i.e. num2
number2 = Double.parseDouble(num2); //reads number2
num3 = JOptionPane.showInputDialog("num3"); //shows a dialog box prompting user to enter value of third number i.e. num3
number3 = Double.parseDouble(num3); //reads number3
if(number1>0&& number2>0 && number3>0){ //checks if all three numbers are positive
sum = number1 + number2+ number3; //displays the sum by adding all three positive numbers
JOptionPane.showMessageDialog(null, "the sum is : " + sum , "Results", JOptionPane.PLAIN_MESSAGE ); } // displays the result of sum in a message dialog box
if(number1<0 && number2>0 && number3>0) { //checks if number2 and number3 are positive
product = number2*number3; //computes product
JOptionPane.showMessageDialog(null, "the product is : " + product , "Results", JOptionPane.PLAIN_MESSAGE ); } //displays the result
else if (number2<0&&number1>0&&number3>0){ //checks if number1 and number3 are positive
product = number1*number3; //computes product
JOptionPane.showMessageDialog(null, "the product is : " + product , "Results", JOptionPane.PLAIN_MESSAGE ); } //displays the result
else if (number3<0 && number1>0 && number2>0) { //checks if number1 and number2 are positive
product = number1*number2; //computes product of 2 positive numbers
JOptionPane.showMessageDialog(null, "the product is : " + product , "Results", JOptionPane.PLAIN_MESSAGE ); } //displays the result
else { /.if all the numbers are positive.
/*However this part is optional. You can just use else part for above else if statement and exclude this else part. In this way the product of all three positive numbers is not computed and product is only computed when only two numbers of the three are positive */
product = number1*number2*number3; //computes product of all three positive numbers
JOptionPane.showMessageDialog(null, "the product is : " + product , "Results", JOptionPane.PLAIN_MESSAGE ); } //displays the result
Scanner scan = new Scanner(System.in); //creates a Scanner class object
double value1 , value2, quotient; //declares variables to hold the values of two real numbers and the result of division of the two real numbers is stored in quotient variable
System.out.println("Enter the first real number: "); //prompts user to enter the value of first real number from the console
value1 = scan.nextDouble(); //reads the first number from user
System.out.println("Enter the second real number : "); //prompts user to enter the value of second real number from the console
value2 = scan.nextDouble(); //reads the second number from user
if(value1<0&&value2<0) { //checks if both the numbers are negative
quotient = value1/value2; //compute the quotient
JOptionPane.showMessageDialog(null, "the quotient is : " + quotient , "Results", JOptionPane.PLAIN_MESSAGE ); } //displays result
else //if both numbers are not negative
JOptionPane.showMessageDialog(null, "Both numbers are not negative" ); //displays this message in a dialog box
} }
Explanation:
In the above given code if you want to display the outputs in console then alter the following statements as follows:
if(number1>0&& number2>0 && number3>0){
sum = number1 + number2+ number3;
System.out.println("the sum is : " + sum); }
if(number1<0 && number2>0 && number3>0) {
product = number2*number3;
System.out.println("the product is : " + product); }
else if (number2<0&&number1>0&&number3>0){
product = number1*number3;
System.out.println("the product is : " + product); }
else if (number3<0 && number1>0 && number2>0) {
product = number1*number2;
System.out.println("the product is : " + product); }
else {
product = number1*number2*number3;
System.out.println("the product is : " + product); }
Scanner scan = new Scanner(System.in);
double value1 , value2, quotient;
System.out.println("Enter the first real number: ");
value1 = scan.nextDouble();
System.out.println("Enter the second real number : ");
value2 = scan.nextDouble();
if(value1<0&&value2<0) {
quotient = value1/value2;
System.out.println("the quotient is : " + quotient); }
else
System.out.println("Both numbers are not negative");
Notice that all the JOptionPane.showMessageDialog statement are changed with System.out.println which prints the results on the console.

Create a Boolean function odd_number_digits(n) that returns True when a positive integer has an odd number of digits. (You may assume that I will not use a number greater than 1,000,000.) Then, use it to make a
function sum_odd_digits(n) that sums all the numbers from 0 to n that have an odd number of digits.
Answer:
Following are the code to this question:
import java.util.*;//import package for user input
public class Main//defining class main
{
public static boolean odd_number_digits(int n)//defining boolean method odd_number_digits
{
if(n>0 && n%2!=0)//defining if block that check value is positive and odd number
{
return true;//return value true
}
else//defining else block
{
return false;//return false value
}
}
public static void sum_odd_digits(int n)//defining a method sum_odd_digits
{
int sum=0,i;//defining integer variable
for(i=0;i<=n;i++)//defining for loop
{
if(i%2!=0)//defining if block for odd number
{
sum=sum+i;//add odd number
}
}
System.out.print(sum);//use print method to print sum value
}
public static void main(String[] args) //defining main method
{
Scanner ox=new Scanner(System.in);//creating Scanner object
int n= ox.nextInt();//defining integer variable for input value
System.out.print(odd_number_digits(n)+ "\n");//use print method to call method
System.out.println("Sum of odd numbers: ");//print message
sum_odd_digits(n);//calling method
}
}
Output:
please find the attachment.
Explanation:
In the above code, two methods "odd_number_digits and sum_odd_digits" are defined in which the first method return type is boolean because it will true or false value, and the second method returns the sum of odd numbers.
In the "odd_number_digits" method, an integer variable passes as an argument and inside the method, if block is used that check value is a positive and odd number then it will return a true value.
In the "sum_odd_digits" method, it accepts an integer parameter "n", and define integer variable "sum" inside the method, which uses the for loop, inside the loop if block is used that counts odd numbers and adds its in sum and print its value.

Fix the error so that the code works correctly
input (“Enter a number: “)
print (num * 8)
How do I fix the error?
Answer:
num = int(input("Enter a number: "))
print(num * 8)
Explanation:
I highlighted the parts that are added
Since you are getting an input from the user, you need to set the result to a variable. In this case, it is num.
Since it is a number, you need to specify the its type. In this case, it may be int.
Also, the quotation marks must be written as seen.
The corrected program which ensures that the program runs correctly is written thus :
num = int(input("Enter a number: ")
#user supplied input should be assigned to the varibale num
print(num * 8)
#multiplies num by 8 and displays the output.
The num variable in the second line isn't attached to any value, therefore, it will throw an error. The user input value should be attached to the variable, 'num' The second line of code multiplies num by 8 and displays the product.Therefore, if the the user input is 3 ; the final result displayed will be : (3 × 8) = 24.
