Answer:

In the presentation layer of the OSI reference model provides a variety of coding and functions that can be applied in application layer data. Information send by the application layer are ensured by these functions. As, presentation layer is the important layer in the OSI reference model because it is responsible for important services like data compression, data conversion, decryption and encryption.

Encryption at gateway is defined as, when the important data is first encrypted using protocol and then it is transferred in the network. And gateway re-director operates in the presentation layer.

Evaluating sorts given the following array: 41, 32, 5, 8, 7, 50, 11 show what the array looks like after the first swap of a bub

irga5000 [103]

The way that the array will looks like after the first swap of a bubble sort in ascending order is {5,32,41, 8,7,50,11}.

<h3>Who do you Write sort code in JAVA?</h3>

It will be:

class SSort

{

void sort(int array[])

{

int n = array.length;

for (int i = 0; i < 2; i++)

{

int minimum_index = i;

for (int j = i+1; j < n; j++)

if (array[j] < array[minimum_index])

minimum_index = j;

int temp = array[minimum_index];

array[minimum_index] = array[i];

array[i] = temp;

}

void printArray(int array[])

{

int n = array.length;

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

System.out.print(array[i]+" ");

System.out.println();

}

public static void main(String args[])

{

SSort s = new SSort();

int array[] = {41, 32, 5, 8, 7, 50, 11};

s.sort(array);

System.out.println("After first two iteration of Selection sort:");

s.printArray(array);

}

Therefore, The way that the array will looks like after the first swap of a bubble sort in ascending order is {5,32,41, 8,7,50,11}.

Based on the data definition classes identified below, assume you wish to create a Dictionary class that inherits from the Book

BabaBlast [244]

Answer:

Explanation:

The following code is written in Java and creates the constructor for the Dictionary class as requested. This class extends the Book class and assumes that the variables for the title and the cost are part of the Book class, so it simply calls and initializes them using the constructor.

class Dictionary extends Book {

int numberWords;

public void Dictionary(String title, int cost, int numberWords) {

this.title = title;

this.cost = cost;

this.numberWords = numberWords;

}
