This is exactly the same situation as the motor circuit
that "we" ( I ) did yesterday.

Wire it up exactly the same as that one, with the light bulb
in place of the DC motor.

See the attached drawing.

Your finger goes in place of the switch and resistor.

When you touch the contact points, a tiny bit of current
from the battery flows through the resistance of your
finger and into the base. The transistor amplifies this
base current into a large collector-emitter current that
lights the light.

You have been instructed to connect a computer to a group of hosts that have been segmented from the regular network. What kind

san4es73 [151]

Answer: VLAN(Virtual local area network)

Explanation: VLAN(Virtual local area network) is the networking device that displays the flexible nature due to the logical connection of one or more LANs. VLAN is used for the purpose of the management, security, scaling etc.

VLAN also has the ability to provide the segmentation in the network by dividing the physical network into segments and making logical network. Router is the source for maintaining the communication in the VLAN.

Thus according to the requirement mentioned in the question ,VLAN is the network device that should be used.

Write a test program that creates two Rectangle objects—one with width 4 and height 40 and the other with width 3.5 and height 3

BARSIC [14]

Answer:

public class Rectangle {

private double width;

private double heigth;

public Rectangle(double width, double heigth) {

this.width = width;

this.heigth = heigth;

}

public double getWidth() {

return width;

}

public void setWidth(double width) {

this.width = width;

}

public double getHeigth() {

return heigth;

}

public void setHeigth(double heigth) {

this.heigth = heigth;

}

public double perimeter(double width, double heigth){

double peri = 2*(width+heigth);

return peri;

}

public double area(double width, double heigth){

double area = width*heigth;

return area;

}

class RectangleTest{

public static void main(String[] args) {

//Creating two Rectangle objects

Rectangle rectangle1 = new Rectangle(4,40);

Rectangle rectangle2 = new Rectangle(3.5, 35.7);

//Calling methods on the first Rectangel objects

System.out.println("The Height of Rectangle 1 is: "+rectangle1.getHeigth());

System.out.println("The Width of Rectangle 1 is: "+rectangle1.getWidth());

System.out.println("The Perimeter of Rectangle 1 is: "+rectangle1.perimeter(4,40));

System.out.println("The Area of Rectangle 1 is: "+rectangle1.area(4,40));

// Second Rectangle object

System.out.println("The Height of Rectangle 2 is: "+rectangle2.getHeigth());

System.out.println("The Width of Rectangle 2 is: "+rectangle2.getWidth());

System.out.println("The Perimeter of Rectangle 2 is: "+rectangle2.perimeter(4,40));

System.out.println("The Area of Rectangle 2 is: "+rectangle2.area(4,40));

}

Explanation:

Firstly A Rectangle class is created with two fields for width and heigth, a constructor and getters and setters the class also has methods for finding area and perimeters
Then a RectangleTest class containing a main method is created and two Rectangle objects are created (Follow teh comments in the code)
Methods to get height, width, area and perimeter are called on each rectangle object to print the appropriate value
