T/F The two primary sections of the CPU are the arithmetic/logic unit and the control unit

In this lab, you will create a programmer-defined class and then use it in a Java program. The program should create two Rectang

prohojiy [21]

Answer:

class Rectangle{

//private attributes of length and width

private double givenLength;

private double givenWidth;

// constructor to initialize the length and width

public Rectangle(double length, double width){

givenLength = length;

givenWidth = width;

}

// setter method to set the givenlength

public void setGivenLength(double length){

givenLength = length;

}

// setter method to set the givenWidth

public void setGivenWidth(double width){

givenWidth = width;

}

// getter method to return the givenLength

public double getGivenLength(){

return givenLength;

}

// getter method to return the givenWidth

public double getGivenWidth(){

return givenWidth;

}

// method to calculate area of rectangle using A = L * B

public void calculateArea(){

System.out.println("The area of the rectangle is: " + getGivenLength() * getGivenWidth());

}

// method to calculate perimeter of rectangle using P = 2 * (L + B)

public void calculatePerimeter(){

System.out.println("The perimeter of the rectangle is: " + 2 * (getGivenLength() + getGivenWidth()));

}

public class MyRectangleClassProgram{

public static void main(String args[]){

//rectangle1 object is created

Rectangle rectangle1 = new Rectangle(10.0, 5.0);

//rectangle2 object is created

Rectangle rectangle2 = new Rectangle(7.0, 3.0);

//area for rectangle1 is calculated

rectangle1.calculateArea();

//perimeter for rectangle1 is calculated

rectangle1.calculatePerimeter();

//area for rectangle2 is calculated

rectangle2.calculateArea();

//perimeter for rectangle2 is calculated

rectangle2.calculatePerimeter();

}

Write a program that prompts the user to enter two characters and display the corresponding major and year status. The first cha

nydimaria [60]

Answer:

import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Please enter two characters: ");
String inputStr = input.nextLine();
if(inputStr.charAt(0) == 'B' || inputStr.charAt(0) == 'b'){
System.out.println("Biology");
}
else if(inputStr.charAt(0) == 'C' || inputStr.charAt(0)== 'c'){
System.out.println("Computer Science");
}
else if(inputStr.charAt(0) == 'I' || inputStr.charAt(0) == 'i')
{
System.out.println("Information Technology and Systems");
}
else{
System.out.println("Invalid major");
}
int num = Character.getNumericValue(inputStr.charAt(1));
if(num >= 1 && num <= 4){
switch (num){
case 1:
System.out.println("freshman");
break;
case 2:
System.out.println("sophomore");
break;
case 3:
System.out.println("junior");
break;
case 4:
System.out.println("senior");
break;
}
}
else{
System.out.println("Invalid year status");
}
}
}

Explanation:

The code consists of two main parts. The part 1 is to validate the input major and print out the major according to the input character (Line 10 -22). If the input character is not matched with the target letters, a message invalid major will be displayed.

The part 2 is to validate the year status to make sure it only fall within the range of 1-4 (Line 26 -45). If within the range, the program will display the year major accordingly. If not a message invalid year status will be displayed.

"Switches break up _______________ domains and routers break up _____________ domains."

mel-nik [20]

Answer:

Switches break up collision domains and routers break up broadcast domains.

Explanation:

Collision domain depicts the part within a network where a collision can happen.
Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
Too many collisions can result in slow traffic speed and can effect network performance.
So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.

Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.
