Answer:

For shadow passwords the shadow-utils package to be enabled

Explanation:

The shadow-utils package includes the necessary programs forconverting UNIX password files to the shadow password format, plusprograms for managing user and group accounts. The pwconv commandconverts passwords to the shadow password format. The pwunconv commandunconverts shadow passwords and generates a passwd file (a standardUNIX password file). The pwck command checks the integrity of passwordand shadow files. The lastlog command prints out the last login timesfor all users. The useradd, userdel, and usermod commands are used formanaging user accounts. The groupadd, groupdel, and groupmod commandsare used for managing group accounts.

What are the differences and similarities of computer virus and biological virus. Give 4 examples

Papessa [141]

Answer:

During recent months, we’ve witnessed an unexpected and distressing pandemic of a coronavirus disease. What I find especially distressing about it is how the worldwide adversity was caused by just a tiny thing — namely, a virus called SARS-CoV-2.

However, biological viruses have always been a potent threat to humanity, as historic pandemics have proved. No wonder viruses became an ideal weapon model in a totally different world — a world of programming. The first computer viruses were created as early as in the 1970s. Starting as pranks, they evolved to become a major threat to the stability of computer networks worldwide. And the more I think of viruses, both biological and digital, the more amazed I am by their similarities.

We don’t know what kind of challenges viruses of either type will cause in the future, but understanding how they infect, the symptoms they induce, how they spread, and the damage they can cause can help us fight both.

The Common Thread

Let’s start with the basics: What does a virus look like?

computer virus of 1999

The images in Figure 1 might look vastly different, but, essentially, they’re the same: a string of code. In the coronavirus, it’s the RNA genome in a shell; in Melissa, it’s computer code. In both cases, the code is an “instruction” for the virus to follow.

An introduction to object-oriented programming.

Scorpion4ik [409]

Answer:

The csharp program is given below.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

namespace WindowsFormsApplication1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void button6_Click(object sender, EventArgs e)

{

int total = (Convert.ToInt32(textBox1.Text) + Convert.ToInt32(textBox2.Text) + Convert.ToInt32(textBox3.Text) + Convert.ToInt32(textBox4.Text) + Convert.ToInt32(textBox5.Text));

int dozen = total / 12;

int eggs = total % 12;

textBox6.Text = dozen.ToString();

textBox7.Text = eggs.ToString();

}

private void button7_Click(object sender, EventArgs e)

{

textBox1.Text = "";

textBox2.Text = "";

textBox3.Text = "";

textBox4.Text = "";

textBox5.Text = "";

textBox6.Text = "";

textBox7.Text = "";

}

private void button8_Click(object sender, EventArgs e)

{

Close();

}

Explanation:

1. The integer variables are declared for total eggs, number of dozens and number of eggs.

2. The input of each text box is converted into integer by using the Convert.ToInt32() method on the value of that particular text box.

3. All the inputs are added and the sum is assigned to variable, total.

4. The number of dozens are obtained by dividing total by 12 and assigning the value to the variable, dozen.

5. The number of extra eggs are obtained by taking the modulus of total and 12 and the value is assigned to the variable, eggs.

6. The integer values in the variables, dozen and eggs, are converted into string using the ToString() function with that particular value.

dozen.ToString();

eggs.ToString();

7. The text boxes are assigned the respective values of dozens and number of eggs.

textBox6.Text = dozen.ToString();

textBox7.Text = eggs.ToString();

8. Two additional buttons, clear and exit, are also added.

9. The clear button erases the contents of all the text boxes. The Text property of each textbox is set to “” thereby clearing all the text fields.

10. The exit button closes the application using Close() function.

11. The program is made in visual studio and the output is attached.

Design a program that asks the user to enter a series of 20 numbers. The program should store the numbers in a list and then dis

Aleksandr-060686 [28]

Answer:

The following are the program in the Python Programming Language.

#declare the list

lst=[]

#set the for loop

for num in range(1,21):

#get the element of the list from the user

n=int(input('Enter the {} element :' .format(num)))

#add elements in the list

lst.append(n)

print()

#print the minimum number in list

print('The lowest number in the list: ',min(lst))

#print the maximum number in list

print('The highest number in the list: ',max(lst))

#print the total of the list

print('The total of the numbers in the list: ',sum(lst))

#print the average of the list

print('The average of the numbers in the list: ',sum(lst)/len(lst))

Output:

Enter the 1 element :53

Enter the 2 element :65

Enter the 3 element :41

Enter the 4 element :23

Enter the 5 element :21

Enter the 6 element :12

Enter the 7 element :96

Enter the 8 element :85

Enter the 9 element :74

Enter the 10 element :98

Enter the 11 element :75

Enter the 12 element :41

Enter the 13 element :54

Enter the 14 element :56

Enter the 15 element :36

Enter the 16 element :25

Enter the 17 element :14

Enter the 18 element :12

Enter the 19 element :45

Enter the 20 element :65

The lowest number in the list: 12

The highest number in the list: 98

The total of the numbers in the list: 991

The average of the numbers in the list: 49.55

Explanation:

The following are the description of the program.

Firstly, we declare the empty list type variable 'lst' to store elements.
Then, set the for loop statement that iterates from 1 and end at 20.
Then, set a variable that get elements of the list from the user and appends those user defined inputs in the list type variable 'lst'.
Finally, print the lowest and the largest elements in the list as well as print the total and average of the elements in the list.
