Which is an advantage of a computer network?
A. Networked computers can process data and run software faster than single computers.
B. Networks prevent unauthorized access to data and protect equipment.
C. Networked computers are less likely than single computers to suffer equipment failure.
D. Networks allow computers to connect quickly and to share data or equipment.

D. is the answer.............

Write a program to calculate the angle of incidence (in degrees) of a light ray in Region 2 given the angle of incidence in Region 1 and the indices of refraction n1 and n2. (Note: If n2>n1, then for some angles 1, Equation 2 will have no real solution because the absolute value of the quantity will be greater than 1. When this occurs, all light is reflected back into Region 1, and no light passes into Region 2 at all. Your program must be able to recognize and properly handle this condition.) The program should also create a plot showing the incident ray, the boundary between the two regions, and the refracted ray on the other side of the boundary. Test your program by running it for the following two cases: (a) n1= 1.0, n2 = 1.7, and 1= 45°. (b) n1 = 1.7, n2 = 1.0; and 1= 45°

Create a class RightTriangle which implements the API exactly as described in the following JavadocLinks to an external site..

Don't forget - you will need to use the Pythagorean theorem (Links to an external site.) to find the hypotenuse (and therefore the perimeter) of a right triangle. You can find the area of a right triangle by multiplying the base and height together, then dividing this product by 2.

Use the runner_RightTriangle file to test the methods in your class; do not add a main method to your RightTriangle class.

Hint 1 - Javadoc only shows public methods, variables and constructors. You will need to add some private member variables to your RightTriangle class to store the necessary information. Think carefully about what information actually needs to be stored and how this will need to be updated when methods change the state of a RightTriangle object.

Hint 2 - As in the previous lesson's exercise it's helpful to add your method/constructor headers and any dummy returns needed before implementing each one properly. This will allow you to test your code using the runner class as you go along.

This is the runner code:

import java.util.Scanner;

public class runner_RightTriangle{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
RightTriangle t = new RightTriangle();
String instruction = "";
while(!instruction.equals("q")){
System.out.println("Type the name of the method to test. Type c to construct a new triangle, q to quit.");
instruction = scan.nextLine();
if(instruction.equals("getArea")){
System.out.println(t.getArea());
}
else if(instruction.equals("getBase")){
System.out.println(t.getBase());
}
else if(instruction.equals("getHeight")){
System.out.println(t.getHeight());
}
else if(instruction.equals("getHypotenuse")){
System.out.println(t.getHypotenuse());
}

else if(instruction.equals("getPerimeter")){
System.out.println(t.getPerimeter());
}
else if(instruction.equals("toString")){
System.out.println(t);
}
else if(instruction.equals("setBase")){
System.out.println("Enter parameter value:");
double arg = scan.nextDouble();
t.setBase(arg);
scan.nextLine();
}
else if(instruction.equals("setHeight")){
System.out.println("Enter parameter value:");
double arg = scan.nextDouble();
t.setHeight(arg);
scan.nextLine();
}
else if(instruction.equals("equals")){
System.out.println("Enter base and height:");
double bs = scan.nextDouble();
double ht = scan.nextDouble();
RightTriangle tOther = new RightTriangle(bs, ht);
System.out.println(t.equals(tOther));
scan.nextLine();
}
else if(instruction.equals("c")){
System.out.println("Enter base and height:");
double bs = scan.nextDouble();
double ht = scan.nextDouble();
t = new RightTriangle(bs, ht);
scan.nextLine();
}
else if(!instruction.equals("q")){
System.out.println("Not recognized.");
}
}
}
}

My code so far:

class RightTriangle{
private double base;
private double height;
public RightTriangle(){
base = 1.0;
height = 1.0;
}
public RightTriangle(double ds, double ht){
base=ds;
height=ht;
}
public boolean equals​(RightTriangle other){
if(base==other.base && height==other.height ){
return true;
}
else
{
return false;
}
}
public double getArea()
{
return (base*height)/2;
}
public double getBase(){
return base;
}
public double getHeight()
{
return height;
}
public double getHypotenuse()
{
return Math.sqrt((base*base)+(height*height));
}
public double getPerimeter()
{
return base+height+Math.sqrt((base*base)+(height*height));
}
void setBase (double bs)
{
if(bs==0){
System.exit(0);
}
else{
base=bs;
}
}
public void setHeight(double ht){
if(ht==0){
System.exit(0);
}
height=ht;
}
public java.lang.String toString()
{
return "base: "+base+" hegiht: "+height+" hypothesis: "+ Math.sqrt((base*base)+(height*height));
}

}

MY CODE SAYS THAT THE setHeight and setBase and toString METHODS ARE INCORRECT.

Why do we use for loops with arrays?
Group of answer choices

For loops let us access one specific element of an array.

Lets us quickly process contents of the array.

To store one piece of data at a time.

For loops let Python handle the values as strings not numbers.

Designing a medium to large network requires a combination of technologies and there isn't one "right way." Think about the technologies you would need to deploy to implement a college campus network with multiple buildings, hundreds of faculty and staff, and dozens of computer-equipped - classrooms and labs. Think of the ancillary technologies you might need to integrate into the network such as data projectors, smart whiteboards, campus security systems, and so forth. Consider consulting with the IT staff at your school or another school to see what technologies they use. Instructions: Write a post of at least four paragraphs outlining the technologies you would use to connect student and faculty computers, servers, multiple buildings and so forth.​

Given the user inputs, complete a program that does the following tasks: Define a set, fruits, containing the user inputs: my_fruit1, my_fruit2, and my_fruit3. Add the user inputs, your_fruit1 and your_fruit2, to fruits. Add the user input, their_fruit, to fruits. Add your_fruit1 to fruits. Remove my_fruit1 from fruits. Observe the output of each print statement carefully to understand what was done by each task of the program. Note: For testing purposes, sets are printed using sorted() for comparison, as in the book's examples. Ex: If the input is:

#include <iostream>
using namespace std;

int main()
{
int num1, num2,r,i;

cout<<"Enter a start: ";
cin>>num1;
cout<<"Enter an end: ";
cin>>num2;
cout<<"\n\nODD NUMBERS\n";

for(i=num1; i<=num2; i++){
r=i%2;
if(r==1)
cout<<" "<<i;

}
cout<<"\nEVEN NUMBERS\n";

for(i=num1; i<=num2; i++){
r=i%2;
if(r==0)
cout<<" "<<i;
}
if(num1>num2){
cout<<"ERROR! Starting Number is GREATER THAN the Ending Number!!!";
return 0;
}
}

Using while loop, do while and for loop write a C++ program that lets you input a starting and ending integer (range) then display all the odd integers and the even integers within the range then compute the sum of each set of integers.:

If the starting number is greater than ending number, the program should display “ERROR! Starting Number is GREATER THAN the Ending Number!!!”.

Sample output:

Enter a start: 1

Enter an end: 10

ODD NUMBERS

1 3 5 7 9 Sum: 25

EVEN NUMBERS

2 4 6 8 10 Sum: 30

How is technology powerless?

#Python: The given program reads a list of single-word first names and ages (ending with -1), and outputs that list with the age incremented. The program fails and throws an exception if the second input on a line is a string rather than an integer. At FIXME in the code, add try and except blocks to catch the ValueError exception and output 0 for the age.

Ex: If the input is:

Lee 18
Lua 21
Mary Beth 19
Stu 33
-1
then the output is:

Lee 19
Lua 22
Mary 0
Stu 34

"# Split input into 2 parts: name and age
parts = input().split()
name = parts[0]
while name != '-1':
# FIXME: The following line will throw ValueError exception.
# Insert try/except blocks to catch the exception.
age = int(parts[1]) + 1
print('{} {}'.format(name, age))

# Get next line
parts = input().split()
name = parts[0]"
