Encryption that uses 16-character keys is known as ____. strong 128-bit encryption strong 256-bit encryption military-strength 5
allsm [11]

Answer: Strong 128-bit encryption.

Explanation: An individual character corresponds to 8 bits . So if there are 16 characters then,

16\times8=128 bits keys

This makes the 128 bit key encryption the strongest amongst all other options.It is strongest because it is almost impossible to decode the 128-character key  by any method e.g.-brute-force method.

Other options are incorrect because the characters given by the other bits are as follows:  {\frac{256}{8}=32 characters

                         {\frac{512}{8}=64 characters

                         {\frac{512}{8}=128 characters  

Thus, the strongest character key is of 128 bits. for cipher.

Using the scenario below, answer the following questions:
4vir4ik [10]

Answer:

Here is code in java.

import java.util.*;

class Main

{

public static void main (String[] args) throws java.lang.Exception

{

   try{

         boolean flag=false;

         int total_mile=0;

         double avg_mile;

       // part 1, create and initialize array

       int inp[]={2,5,9,11,13,17,20,22,24,26};

       

       System.out.print("miles ran per week: ");

       // print the miles per week of train

       for(int x=0;x<10;x++)

       {

       System.out.print(inp[x]+" ");

       }

        System.out.println();

       //part 2, print the value of index 2 in the list

       System.out.println("value at index 2: "+inp[2]+" miles");

       //part 3, find length of array

       System.out.println("list length: "+inp.length);

     

       // part 4, calculate total mile and average

       for(int y=0;y<10;y++)

       {

       total_mile=total_mile+inp[y];

       }

       System.out.println("total miles ran: "+total_mile+" miles");

       

       avg_mile=total_mile/10.0;

       System.out.println("average no of miles ran= "+avg_mile+" miles");

       

     // part 5, check 4 exist in the list or not

       for(int k=0;k<10;k++)

       {

       if(inp[k]==4)

       {

       flag=true;

       break;

           }

       }

           if(flag)

           System.out.println("4 exist in the list.");

           else

            System.out.println("4 doesn't exists in the list.");  

       

   }catch(Exception ex){

       return;}

}

}

Explanation:

Create and initialize array with list value equals to 2 and maximum value 26. Print the miles of each week.Then find the value of miles at index 2 in the list.Next find the length of the array and print it.Calculate total miles ran of 10 weeks.Then calculate the average miles by dividing the total with 10. In the array, check 4 exist or not.

Output:

miles ran per week: 2 5 9 11 13 17 20 22 24 26                                                                            

value at index 2: 9 miles                                                                                                  

list length: 10                                                                                                            

total miles ran: 149 miles                                                                                                

average no of miles ran= 14.9 miles                                                                                        

4 doesn't exists

Review universal data models and discuss how these are being used more widely today. Does a data modeling project using a packag
adell [148]

Answer:

2. A data modelling project using a packaged data model REQUIRES A GREATER SKILL than a project not using a packaged data model.

Explanation:

1a. Review of universal models:

A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real world entities. It has become the standard approach used towards designing databases.

A universal data model is a template data model that can be reused as a starting point or a building block to jump-start development of a data modelling project, industry specific model, logical data models.

1b. Discuss how these are being used more widely today.

*Universal data models helps professional reduce development time, improve consistency and standardization while achieving high quality models.

*Higher quality: just as architects consider blue prints before constructing a building, one should also consider data before building an app. A data model helps define the problem, enabling one to consider different approaches and choose best ones.

*By properly modelling and organization's data, the database designer can eliminate data redundancies (needless repetitions) which are a key source for inaccurate information and ineffective systems.

2. Greater and advanced skills are adequate and required when data modelling project is done using packaged data model while fewer skills are required when data modelling is done without packaged data model.
