Describe the user interface in other high-technology devices commonly found in the home or office, such as a smartphone, HD television, fitness watch, or microwave oven. Pick one specific device and discuss how well its interface is designed and how easy it is to use. Does the device use the same techniques as computer system interfaces, such as menus and icons

Answer:

Collision or electromagnetic interference (EMI)

Explanation:

Some network cables connected to switch or router ports are prone to internal collision (between two frames or packets) and external collision with electromagnetic waves from other sources (EMI).

Electromagnetic waves are also known as radio waves or signals. When they are transmitted, the network cable acts as a receiver, the received signal interferes with the packet in the cable. This is why the cyclic redundancy check (CRC) throws an error.

Answer:

Explanation:

The following code is written in Java. It is a function that takes in the ArrayList called ArrayBag as a parameter and randomly removes one of the elements in the ArrayList. As long as the ArrayBag has at least 1 element it will return true otherwise it will return false.

public static boolean removeRandom(ArrayList ArrayBag) {

               Random rand = new Random();

               if (ArrayBag.size() > 0) {

                       int randomNumber = rand.nextInt(ArrayBag.size());

                       ArrayBag.remove(randomNumber);

                       return true;

               } else {

                       return false;

               }

       }

Answer:

Explanation:

The code in C++ is written as:

#include <iostream>

using namespace std;

int smallestIndex(int arr[],int size)

{

int min=arr[0],ind=0;

for(int i=0;i<size;i++)

{

if(min>arr[i])

{

min=arr[i];

ind=i;              NOTE: ind serves as a variable that is holding the smallest

}                                   element index of array

}

return ind;

}

int main() {

int arr[15];

cout<<"Enter 15 integers: ";

for(int i=0;i<15;i++)

cin>>arr[i];

for(int i=0;i<15;i++)

cout<<arr[i]<<" "<<endl;

int index=smallestIndex(arr,15);

cout<<"The position of the first occurrence of the smallest element in list is: "<<index<<endl;

cout<<"The smallest element in list is: "<<arr[index];

}

OUTPUT:

Enter 15 integers:

4

5

8

4

6

1

2

1

4

5

7

9

5

7

8

4   5  8  4  6  1  2  1  4  5  7  9  5  7  8  

The position of the first occurrence for the smallest element in the list is 5

The smallest element in the list is: 1

Answer:

Following are the program to this question:

#include <iostream>//header file

using namespace std;//namespace

class Val //defining abstract class

{

  public://use access specifier

     virtual int squ()=0;//declaring a method squ  

     void setval(int x) //defining a method setval

     {

        a=x;//holding value in a variable

     }

  protected://use access specifier

     int a;//defining integer variable

};

class square: public Val //defining a class square that inherit abstract class

{

  public://use access specifier

   int squ() //defining squ method

   {  

   return (a*a); //return square value

   }

};

int main() //main method

{

 square s;//creating class object

 s.setval(5);//calling setval method

 cout << "The square value is: " << s.squ() << endl;//print value by calling squ method

}

Output:

The square value is: 25

Explanation:

In the above code a two-class "Val and square" is declared, in which val is abstract class, in a method squ is declared, and setval is used to set the value.

In the next step, the square class inherits Val and defines the squ method, and uses the return keyword to return its calculated value.

In the main method square class object is created and set the setval value and call the squ method and print its value.    

Answer:

with open("file1.txt", "r") as file:

lines = file.readlines()

mydict = dict()

for x in range(0, len(lines) - 1, 2):

mydict[lines[x]] = lines[x-1]

dict_keys = sorted(mydict.keys)

sorted_dict ={}

for key in dict_keys:

sorted_dict[key] = mydict[key]

with open("output_keys.txt", "a+") as writn:

for key, value in sorted_dict.items():

writn.write(key: value)

writn.write("\n")

dict_values = sorted(mydict.values)

with open("output_titles", "a+") as title:

for name in dict_values:

title.write(name)

title.write("\n")

Explanation:

The python program above reads in the file context, files.txt, and creates a dictionary of the file with the number of seasons as the key and movie title as the value. The sorted dictionary is saved in the output_keys.txt file and the titles in output_titles.txt file.
