You have received an update package for a critical application you are running on a virtual machine. You have been told to insta

The first thing to do install the package without having downtime is; Virtualization.

<h3>What is virtualization? </h3>

Virtualization is defined as the ability to install and run multiple operating systems simultaneously on a single physical computer virtually.

Now, virtualization has many advantages for server administrators. This is because as an administrator, your job is made easier due to the several tasks you can perform on a virtual machine instead of on a physical machine.

Since there should be no down time, then it is advisable to first carry out virtualization.

Write a program that produces a Caesar cipher of a given message string. A Caesar cipher is formed by rotating each letter of a
PilotLPTM [1.2K]

Answer:

Here is the JAVA program that produces Caeser cipher o given message string:

import java.util.Scanner;  //to accept input from user

public class Main {  

   public static void main(String args[]) {  //start of main function

       Scanner input = new Scanner(System.in);  //creates object of Scanner

       System.out.println("Enter the message : ");  //prompts user to enter a plaintext (message)

       String message = input.nextLine();  //reads the input message

       System.out.println("Enter the amount by which by which to rotate each letter : ");  //prompts user to enter value of shift to rotate each character according to shift

       int rotate = input.nextInt();  // reads the amount to rotate from user

       String encoded_m = "";  // to store the cipher text

       char letter;  // to store the character

       for(int i=0; i < message.length();i++)  {  // iterates through the message string until the length of the message string is reached

           letter = message.charAt(i);  // method charAt() returns the character at index i in a message and stores it to letter variable

           if(letter >= 'a' && letter <= 'z')  {  //if letter is between small a and z

            letter = (char) (letter + rotate);  //shift/rotate the letter

            if(letter > 'z') {  //if letter is greater than lower case z

               letter = (char) (letter+'a'-'z'-1); }  // re-rotate to starting position  

            encoded_m = encoded_m + letter;}  //compute the cipher text by adding the letter to the the encoded message

           else if(letter >= 'A' && letter <= 'Z') {  //if letter is between capital A and Z

            letter = (char) (letter + rotate);  //shift letter

            if(letter > 'Z') {  //if letter is greater than upper case Z

                letter = (char) (letter+'A'-'Z'-1);}  // re-rotate to starting position  

            encoded_m = encoded_m + letter;}  //computes encoded message

           else {  

         encoded_m = encoded_m + letter;  } }  //computes encoded message

System.out.println("Encoded message : " + encoded_m.toUpperCase());  }} //displays the cipher text (encoded message) in upper case letters

Explanation:

The program prompts the user to enter a message. This is a plaintext. Next the program prompts the user to enter an amount by which to rotate each letter. This is basically the value of shift. Next the program has a for loop that iterates through each character of the message string. At each iteration it uses charAt() which returns the character of message string at i-th index. This character is checked by if condition which checks if the character/letter is an upper or lowercase letter. Next the statement letter = (char) (letter + rotate);   is used to shift the letter up to the value of rotate and store it in letter variable. This letter is then added to the variable encoded_m. At each iteration the same procedure is repeated. After the loop breaks, the statement     System.out.println("Encoded message : " + encoded_m.toUpperCase()); displays the entire cipher text stored in encoded_m in uppercase letters on the output screen.

The logic of the program is explained here with an example in the attached document.

A data structure used to bind an authenticated individual to a public key is the definition of ________.
patriot [66]

Answer:

Digital Certificate is the correct answer of this question.

Explanation:

Digital certificates are always for encryption and identification for transmitting public keys.The concept of digital certificate is a data structure used for linking an authenticated person to a public key. It is used to cryptographically attach public key rights to the organization that controls it.

<u>For example</u>:- Verisign, Entrust, etc.

  • An appendix to an electronic document that is used for authentication purposes.
  • A digital certificate's most frequent use is to confirm that an user sending a message is who he or she appears to be, and provide the recipient with the means to encode a response.

You are the manager and an employee shows up for his shift dressed inappropriately for work. What should you do?
yarga [219]

Most managers see inappropriate dressing every day. Some are left angered while some are confused as to what is the right way to approach such situations. What follows next needs to be professional oriented. Being the manager, I would start by finding out what the appropriate dressing policies are. Some companies might have dress code policies while others might not. Assuming that this company has, I would read these policies carefully. The next thing that is required from me is to have a small conversation with the employee discretely. As professional as I can be, I will mention how I feel his or her dress code is inappropriate and try to summon the employee by asking him or her whether they are fully aware of the appropriate dress code. I will try to agree with the employee on what is appropriate and what is not. If we agree, requesting the employee to home and change clothes is unnecessary, but if the need to do that arises, I would consider that to be an option.
