why do we need to settle technology in business?
Answer:
Technology has important effects on business operations. No matter the size of your enterprise, technology has both tangible and intangible benefits that will help you make money and produce the results your customers demand. Technological infrastructure affects the culture, efficiency and relationships of a business.
Consider a model of a drone to deliver the orders of the customers within the range of 20 km of the coverage area.
Identified at least 5 factors (inputs) required to experiment with the above mention system model (e.g. speed of the drone).

For this lab you will write a class to create a user-defined type called Shapes to represent different shapes, their perimeters and their areas. The class should have three fields: shape, which is of type string, and perimeter and area of type double. The program will have to be able to calculate perimeters and areas for circles, triangles, squares and rectangles, which are the known shapes.
2.1 Constructors
Write these constructors:
1. Default constructor that sets the shape to "unknown" and the perimeter and area to 0
2. Constructor with one parameter, shape, that sets the shape, other fields are 0
2.2 Accessors & Mutators
Write the following member methods:
1. setShape()
Modifies the shape field
2. getShape()
Returns the shape field
3. getPerimeter()
Returns the perimeter field
4. getArea()
Returns the area field
Arithmetic Methods in Interface
Write the following member methods to perform arithmetic:
1. setPerimeter(Scanner scnr)
Depending on the shape, prompts the user for appropriate variables (ie width & height for a square, radius for a circle, etc.) and calculates the perimeter of the appropriate shape. The perimeter field should be updates with the new value. If the shape is unknown, then print to the screen that the user must first define a shape before a perimeter can be calculated and set the perimeter to 0.
2. setArea(Scanner scnr)
Depending on the shape, prompts the user for appropriate variables (ie width & height for a square, radius for a circle, etc.) and calculates the area of the appropriate shape. The area field should be updates with the new value. If the shape is unknown, then print to the screen that the user must first define a shape before an area can be calculated and set the area to 0.
2.3 Additional Methods
Create two additional methods of your choice. Be sure to clearly label both of these methods as your own.
2.4 Using another .java file called ShapesTest.java that tests that all of your methods work correctly

}
//2. Method to find and show the difference between the area and perimeter of a shape
public void getDifference(){
double diff = this.getArea() - this.getPerimeter();
System.out.println();
System.out.println("The difference is " + diff);
}
}
========= ShapeTest.java ===========
import java.util.Scanner;
public class ShapeTest {
public static void main(String [] args){
Scanner scanner = new Scanner(System.in);
// create an unknown shape
Shape shape_unknown = new Shape();
//get the shape
System.out.println("The shape is " + shape_unknown.getShape());
//set the area
shape_unknown.setArea(scanner);
//get the area
System.out.println("The area is " + shape_unknown.getArea());
//set the perimeter
shape_unknown.setPerimeter(scanner);
//get the perimeter
System.out.println("The perimeter is " + shape_unknown.getPerimeter());
// create another shape - circle
Shape shape_circle = new Shape("circle");
//set the area
shape_circle.setArea(scanner);
//get the area
System.out.println("The area is " + shape_circle.getArea());
//set the perimeter

//get the area
System.out.println("The perimeter is " + shape_circle.getArea());
//get the properties
shape_circle.showProperties();
//get the difference between area and perimeter
shape_circle.getDifference();
}
}
Sample output:
The shape is unknown
You must define a shape first before calculating area
The area is 0.0
You must define a shape first before calculating perimeter
The perimeter is 0.0
Enter the radius of the circle
>> 12
The area is 452.448
Enter the radius of the circle
>> 12
The perimeter is 452.448
The properties of the shape are
Shape : circle
Perimeter : 75.408
Area : 452.448
The difference is 377.03999999999996

What is the first thing you should do when you discover a computer is infected with malware? The second thing?
Answer:
Quarantine the computer.
Explanation:
Malware can be characterized with negative software capable of causing various damages to a computer, such as theft of data and information, in addition to damage to devices.
In order to avoid having your computer infected with malware, it is essential to have installed reliable malware-checking software, in addition to taking all appropriate security measures when accessing the internet and never clicking on unknown or suspicious links.
Therefore, when realizing that the computer has been infected by malware, it is necessary to quarantine the computer and immediately disconnect from a network so that it does not infect other computers. The quarantine acts as an action where the infected file is moved to an encrypted folder where the malware cannot be executed and spread by the operating system.

The XYZ daycare has installed a new high-tech system for keeping track of which children are under its supervision at any moment in time. Each parent of a child has a card with a unique ID, where the ID is some integer x. Every morning, the parent swipes the card at a card-reader when dropping their child off at the daycare. The system then adds x to an array of integers. In the evening, when the parent comes to pick up the child, the same card is swiped, and a second copy of x is added to the list. Each night at midnight, the array is wiped clean and reset to have zero elements. In this way, the daycare can quickly check every afternoon which children are yet to be picked up by their parents by picking out the array elements that occur precisely once. Unfortunately, at 4:55 pm on Thursday, April 20, 2017, the daycare realizes that somewhere in their daycare is precisely one child who is yet to be picked up. Can you help them determine the integer ID of this child
Answer:
Use or Add a log of the actions of the system including the integer, the action, and the time. Scroll through and see which integer was added but was not removed.
Explanation:
I wouldn't be able to program this, but I think a log is the best solution for this.

Explanation:
For two integers m and n, their GCD(Greatest Common Divisor) can be computed by a recursive function. Write a recursive method gcd(m,n) to find their Greatest Common Divisor. Once m is 0, the function returns n. Once n is 0, the function returns m. If neither is 0, the function can recursively calculate the Greatest Common Divisor with two smaller parameters: One is n, the second one is m mod n. Although there are other approaches to calculate Greatest Common Divisor, your program should follow the instructions of this question, otherwise you will not get the credit. Then write a testing program to call the recursive method.
Answer:
In Python:
def gcd(m,n):
if n == 0:
return m
elif m == 0:
return n
else:
return gcd(n,m%n)
Explanation:
This defines the function
def gcd(m,n):
If n is 0, return m
if n == 0:
return m
If m is 0, return n
elif m == 0:
return n
If otherwise, calculate the gcd recursively
else:
return gcd(n,m%n)
To call the function to calculate the gcd of say 15 and 5 from main, use:
gcd(15,5)
