In this problem, we want to compare the computational performance of symmetric and asymmetric algorithms. Assume a fast public-k

ey library such as OpenSSL [132] that can decrypt data at a rate of 100 Kbit/sec using the RSA algorithm on a modern PC. On the same machine, AES can decrypt at a rate of 17 Mbit/sec. Assume we want to decrypt a movie stored on a DVD. The movie requires 1 GByte of storage. How long does decryption take with either algorithm

Answer:

The AES decryption time is 8 minutes

Explanation:

GIVEN THAT:

The 1 GByte is equal to 230 bytes and equal to 233 bits

The RSA decryption time is calculated as = 233 / (100*230 )

= 83886. 06 seconds

= 23 hours

The RSA decryption time is 23 hours

The AES decryption time is calculated as = 233 / (17 * 230 )

= 481.81 seconds

= 8 minutes .

The AES decryption time is 8 minutes

In a C++ program, one and two are double variables and input values are 10.5 and 30.6. After the statement cin &gt;&gt; one &gt;
SSSSS [86.1K]

Answer:

variable one stores 10.5 and two stores 30.6

Explanation:

In c++ language, the cout keyword is used to write to the standard output. The input from the user is taken by using the cin keyword.

For the input from the user, a variable need is declared first.

datatype variable_name;

The input can be taken one at a time as shown.

cin >> variable_name;

The input for more than one variable can be taken in a single line as given by the syntax below.

1. First, two variables are declared.

datatype variable_name1, variable_name2;

2. Both input is taken simultaneously as shown.

cin >> variable_name1, variable_name2;

For the given scenario, two double variables are declared as below.

double one, two;

The question mentions input values for the two double variables as 10.5 and 30.6.

3. The given scenario takes both the values as input at the same time, in a single line as shown below.

cin >> one >> two;

4. After this statement, both the values entered by the user are accepted.

The values should be separated by space.

First value is stored in the variable one.

Second value is stored in the variable two.

5. The user enters the values as follows.

10.5 30.6

6. The value 10.5 is stored in variable one.

7. The value 30.6 is stored in variable two.

The c++ program to implement the above is given below.

#include <iostream>

using namespace std;

int main() {

   double one, two;      

   cout << " Enter two decimal values " << endl;

   cin >> one >> two;

   cout << " The input values are " << endl;

   cout << " one : " << one << " \t " << " two : " << two << endl;

   return 0;

}

OUTPUT

Enter two decimal values  

10.5 30.6

The input values are  

one : 10    two : 530.6

Nadeen runs a website on vegan lifestyle. She wants to spread the word and make more people visit her site to read her recipes a
pashok25 [27]

What Nadeen needs to do to get people to engage with her web site is to regularly post new content and regularly respond to user comments and questions (options A and C).

<h3>What should Nadeen do to increase visits to her website?</h3>

Currently, social networks and pages have become tools to share information and create a community of people around a topic.

From this trend, many people have developed their own web pages to share their knowledge and experience with other people so that knowledge becomes public and help those who do not have as much knowledge.

However, for a page to have high interactions and visits from the public, the owner of the page must ensure that they comply with some recommendations that will increase the traffic of their page, such as:

  • Post frequently: This is because people are constantly looking for information and like to be up to date with the latest.
  • Respond to user comments and questions: This creates a link between the page owner and their visitors that makes them feel comfortable with this page. This also helps the owner create a community where everyone participates by contributing knowledge.

Note: This question is incomplete because the options are missing. Here are the options:

A. She must post new content on her website regularly.

B. She must increase the number of pay-per-click advertisements on her website.

C. She must regularly respond to user comments and questions.

D. She must use a secure payment gateway.

The sum of the deviations of each data value from this measure of central location will always be zero. A. Median B. Standard de
JulijaS [17]

Answer:

C. Mean

Explanation:

Mean = (∑x_{i})/N

Median = central values when data is sorted

Mode = most repeated value

Standard deviation = \sqrt{sum(x_{i}-mean)^{2}/N}

In standard deviation, formula you may see that deviation is being calculated from the mean (central location). But here we take square of the value before adding all of them.

But if we just take sum(x - mean), it would be equal to zero.

<u>EXAMPLE</u>

Take 4, 9, 5 as data

mean = (4+9+5)/3 = 18/3 = 6

sum of deviations from mean = (4-6)+(9-6)+(5-6) = (-2)+(3)+(-1) = 0
