Artist 52 [7]

MCKibben argues that the inhabitable planet is shrinking because:

Consistently higher temperatures will likely make certain areas uninhabitable

Desertification will reduce the amount of harvestable land

Coastlines are being lost to sea level rise.

<h3>What is Shrinking?</h3>

This is the process in which an object or place becomes smaller as a result of various activities.

The most suitable options which explains why the planet is shrinking is as a result of a reduction in the areas in which humans can live as a result of the factors mentioned above.

Write a method transpose, that takes as argument a 2D array of integers, myTable, and returns the transpose of myTable. The tran

Gelneren [198K]

Answer:

The program to this question can be given as:

Program:

import java.util.*; //import package

public class Main //defining class

{

public static int[][] transpose(int[][] a1) //defining function transpose

{

int i,j; //define variables

int[][] transpose = new int[a1[0].length][a1.length]; //define variable transpose.

//loop for transpose matrix.

for(i = 0; i < a1.length; i++)

{

for(j = 0; j < a1[i].length; j++)

{

transpose [j][i] = a1[i][j]; //hold value in transpose variable

}

return transpose ; //return transpose matrix.

}

public static void main(String[] args) //main method.

{

int row,col,i,j; //defining variable.

Scanner obj = new Scanner(System.in); //creating Scanner class Object

System.out.print("Enter number of rows: ");//message

row = obj.nextInt(); //input rows form user.

System.out.print("Enter number of columns: ");//message

col = obj.nextInt(); //input columns form user.

int[][] a1 = new int[row][col]; //defining array.

System.out.println("Enter matrix"); //message

// loop for input array elements from user

for(i=0; i<a1.length;i++)

{

for(j=0; j<a1[i].length;j++)

{

a1[i][j]=obj.nextInt(); //input in array variable.

}

System.out.println("Matrix you insert :"); //message

// loop for display array.

for(i=0; i<a1.length;i++)

{

for(j=0; j<a1[i].length;j++)

{

System.out.print(a1[i][j]+" "); //print matrix

}

System.out.print("\n");

}

int[][] result = transpose(a1); //define result array variable that holds function value.

System.out.println("Transposed matrix is :");

//use loop for print Transpose matrix.

for(i = 0;i < result.length;i++)

{

for (j = 0; j < result[i].length;j++)

{

System.out.print(result[i][j] + " "); //print matrix

}

System.out.print("\n");

}

Output:

Enter number of rows: 2

Enter number of columns: 3

Enter matrix

2

3

4

9

8

7

Matrix you insert :

2 3 4

9 8 7

Transposed matrix is :

2 9

3 8

4 7

Explanation:

The description of the above program can be given as:

In the above program firstly import a package, then declare a class that is "Main" inside a class defining a transpose() function this function returns a matrix in transpose form.
In the main class, we define a variable and matrix that is "row, col, i, j and a1[][]". Then we Creating a scanner class object, which is used by row, col and a1[][] variables for user input.
The row and col variables are used to declare matrix size and i, j variable is used in the loop for insert and display matrix.
a1[][] matrix is used for input matrix elements and passes into transpose() function as an argument that returns a value that is held in the result variable. This is used as a loop for the print transpose matrix.

A company is executing a strategy to encrypt and sign all proprietary data in transit. The company recently deployed PKI service

Softa [21]

Answer:

A. S/MIME

B. TLS

C. Kerberos

Explanation:

PKI : Public Key Infrastructure is a technique which will allow services or applications to communicate securely across the unsecured network or internet.

PKI mainly consist of CA or Certificate Authority who can issue digital certificates or they are also known as trusted CA. exmaples are godaddy, digicert, verizone, symmantec, etc.. and RA also known as Registration Authorities and they verify if the requested certificates can be stored at CA. Keys will be stored in the central directory.It will also consists of certificate management system and the policies governing PKI.

S/MIME : Secure/Multipurpose Internet Mail Extensions which use assymentric cryptography and sign the MIME data. S/MIME will provide services like Authentication, Encryption , Integrity, Privacy and Non repudiation for messaging applications

SMIME uses certificates which can be self signed or CA certified. It specifies MIME type as $application/pkcs7-mime$ while transmitting the data.

TLS : Transport Layer Security. the earlier versions used to be known as SSL ( Secure Socket Layer) SSLv3 got depreciated and TLSv1.2/1.3 are popularly used to provide encryption, authentication, Integrity and Hashing for client to server side communication.

Most of the applications communicate securely using TLS. They will establish secure TCP connection using SSL Handshake. During the Handshake they will exchange supported versions, ciphersuites and certificates. Applications which uses TLS always uses CA certificates and Inhouse applications can communicate using self signed certificate or even with CA certificates.

HTTPS which is also known as HTTP over SSL is widely used for almost all the web services to communicate securely across the internet.

Kerberos : It is a protocol used to prove the identity for two nodes which are communicating with each other. Kerberos uses both symmetric key cryptography and assymetric key cryptography. However, symmetric key cryptography is used widely and public key cryptography is used optionally.

Authentication server which is also known as AS is used to authenticate the requesting client. It further forwards the user credentials to key distribution center. KDC further issues to TGT ( ticket granting ticket) and it uses TGS's secret key to encrypt. User will receive a encrypted output.

When a User Login then The client authenticates itself to the Authentication Server (AS) which forwards the username to a key distribution center (KDC). The KDC issues a ticket-granting ticket (TGT), which is time stamped and encrypts it using the ticket-granting service's (TGS) secret key and returns the encrypted result to the user's workstation. Sessions will be renewed and managed by users session manager.
