#Write a function called find_max_sales. find_max_sales will #have one parameter: a list of tuples. Each tuple in the #list will have two items: a string and an integer. The #string will represent the name of a movie, and the integer #will represent that movie's total ticket sales (in millions #of dollars). # #The function should return the movie from the list that #had the most sales. Return only the movie name, not the #full tuple. #Write your function here!

Explanation:

Remember, an absolute value is the non-negative value of a number in this case the integer.

First, using the abs() function. Here's an example:

# Some random integers

variableA = -308

variableB = 301

Second, # Get the absolute values of those integers

absA = abs(variableA)

absB = abs(variableB)

Next,

# Output the results

print("Absolute values of integers with `abs()`:")

print("|", variableA, "| = ", absA, sep="")

Finally,

Use abs(variableA-variableB):

In [1]: abs(-308-301)

Out[1]: 307

import java.util.Scanner; //Scanner class to take input from user

public class BandMatrix{ // start of the BandMatrix class

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

   Scanner scanner = new Scanner( System.in );

//creates Scanner class object scanner

              int n = scanner.nextInt(); //reads the value of n from user

                   int width = scanner.nextInt(); //reads input value of width

//the outer and inner loops to form a n by n pattern

   for (int i=0; i<n; i++)    {

       for (int j=0; j<n; j++)        {

           if (j==i || Math.abs(i-j) <= width) {

/*if the value of j become equal to the value of i OR if the difference between i and j is less than or equal to the value of width input by user then asterisks are printed in the pattern otherwise 0 is printed. This simply moves through each element of and calculates its distance from main diagonal */

System.out.print(" * ");   } //displays asterisks when above if condition is true

           else            { //when the above IF condition evaluates to false

 System.out.print(" 0 "); }  }  //displays 0 in pattern when if condition is false    

       System.out.println();    } } }

Explanation:

The program is well explained in the comments mentioned with each statement of the program. The program first takes two integer arguments from user i.e. n and width and uses for loops if (j==i || Math.abs(i-j) <= width) condition to print n-by-n pattern with a zero 0 for each element whose distance from the main diagonal is strictly more than width, and an asterisk * for each entry that is not. I will explain the working of loops.

Suppose n=8 and width=0

The first outer for loop has an i variable that is initialized to 0. This loop executes until the value of i exceeds the value of n. So at first iteration i=0. The loop checks if i<n. Its true because n=8 and i=0 So 8>0. Now the program enters the body of outer loop.

There is an inner loop which has a j variable that is initialized to 0. This loop executes until the value of j exceeds the value of n. So at first iteration j=0. The loop checks if j<n. Its true because n=8 and j=0 So 8>0. Now the program enters the body of inner loop.

There is an if statement inside the body of inner loop. It checks each entry whose distance from the main diagonal is strictly less than or equal width and prints asterisks * when the statement evaluates to true otherwise prints a 0. Lets see how it works.  

i=0 j=0 So j==i is True. If we check the second part of this if statement then

i - j = 0 - 0 = 0. Math.abs() method is used to return the absolute value of this subtraction in case the result comes out to be a negative number. So the result is 0. As the value of width is 0 so this part is true because i-j=0 and width is also 0. So one asterisk is printed when this condition evaluates to true.

This way the loops keeps executing and printing the asterisks or 0 according to the if statement at each iteration. The program along with its output is attached.

Complete Question:

A network security analyst received an alert about a potential malware threat on a user’s computer. What can the analyst review to get detailed information about this compromise? Check all that apply.

A. Logs.

B. Full Disk Encryption (FDE).

C. Binary whitelisting software.

D. Security Information and Event Management (SIEM) system.

Answer:

A. Logs.

D. Security Information and Event Management (SIEM) system.

Explanation:

If a network security analyst received an alert about a potential malware threat on a user’s computer. In order to get a detailed information about this compromise, the analyst should review both the logs and Security Information and Event Management (SIEM) system.

In Computer science, logs can be defined as records of events triggered by a user, operating system and other software applications running on a computer. Log files are used to gather information stored on a computer such as user activities, system performance and software program.

Security Information and Event Management (SIEM) system is the process of gathering and integration of all the logs generated by a computer from various software application, service, process, or security tool.

These logs collected through the SIEM are shown in a format that is readable by the security analyst and this help in real-time detection of threats.

Hence, logs and SIEM systems are important tools for network security analyst for detection of threats in real-time and event management functions.

<?php  

function word_count($string){   // function that takes a string a parameter and returns the number of words in that string

   $space = 0;   // this variable is used in order to detect space, new line and tab spaces in a string

   $words = 1; // this variable is used to identify word presence in string

   $include = $space;  //used to maintain the state of $words and $space

   $counter = 0;  // this counts the number of words in the string

   $i = 0;  //this moves through each character of the string

   while ($i < strlen($string)){  // iterates through every character of string until the last character of string is reached

       if ($string[$i] == " "||$string[$i] == "\n" || $string[$i] == "\t")  //if the space or new line or tab space is identified in the string

           $include = $space;  //set the state of include as space if the next character is a space newline or a tab space

       else if ($include == $space) {  //if next character is a word and current state i.e. $include holds $space

           $include = $words;   //  then set the state i.e. $include as $words

           ++$counter; } //increments i to move to next character at each iteration

       ++$i;  } //returns the number of words in a string

   return $counter; }

$str = "Hello, how are you ";  //sample string

echo "Words: " . word_count($str);  // calls word_count function to return number of words in str.

?>  

Explanation:

The program has a function word_count that accepts a string as its parameter and returns the number of words in the string. In the function there are three variables $space and $words and $include used as state variables. For instance $space identifies space, new line and tab spaces in the $string so it specifies that a space has occurred. $words identifies words in the $string so it specifies that a word has occurred. $include holds this state information. $i moves through every character of the $string and when a space occurs in the $string then the state $include is set to $space. When a word occurs then state $include is set to $words. $counter variable, which is used to count the number of words is incremented to 1 when previous state is $space and next character is a word character. Every time a word is seen in the string, this variable is incremented to 1 to keep track of number of words in the string. When $i reaches the end of the string then this loop stops and counter returns the number of words in the $string.

Explanation:

AES is based on Rijndael Algorithm.

The Rijndael algorithm enables a choice of block sizes and key sizes. The choices are for each of 128, 192, or 256 bits. Once NIST implemented Rijndael for AES, it only specified one block size,128 bits, but maintained three major lengths of selection. IEEE 802.11I go a step and further limits when both the main size and length of the block for 128 bits. It simplifies deployment and relieves users during development from having to make yet again another decision.

Answer:

The answer is option (a) permutation of data at byte level.

Explanation:

Solution

During the process of AES (Advanced encryption Standard) algorithm, these two steps shift rows and mix columns are two sub-steps of process, in which, shift row works on rows and basically shifts nth row by n-1 bytes to left side, that is, the first row will not shift at all, the second row by one place shift left, and apart from it mix columns works on columns. in this each column is transformed with a particular function, so these two steps are very different.

Answer:

a. 2100

b. 2199

Explanation:

GIven that:

The file size = 1000 MB

The  payload size is  = 100 bytes

The negotiated window size is = 1000 bytes.

This implies that the sliding window can accommodate maximum number of 10 packets

The sender receives an ACK 1200 from the receiver.

Total byte of the file is :

1000 MB = 1024000000 bytes

a.

Sender receives an ACK 1200 from the receiver but still two packets are still unacknowledged

=1200 + 9 * 100

= 1200 +  900

= 2100

b. What is the last byte number that can be sent without an ACK being sent by the receiver?

b. Usually byte number starts from zero, in the first packet, the last byte will be 99 because it is in 1000th place.

Thus; the last byte number send is :

= 1200 + 10 *100 -1

= 1200 + 1000-1

= 1200 + 999

= 2199

Answer:

(c) the dynamic type of reference will determine which of the methods to call.

Explanation:

Polymorphism in Object Oriented Programming typically means the same method name can cause different actions depending on which object it is invoked on. Polymorphism allows for dynamic binding in that method invocation is not bound to the method definition until the program executes.

So in the case of Animal superclass and Mammal subclass, both having a method called eat() with identical signatures and return types, depending on which reference, the correct method eat() will be called dynamically upon execution.

For example, if we have the following;

================================

Mammal mammal = new Animal();

mammal.eat()

================================

The eat() method that will be called is the one in the Mammal subclass.

However, if we have;

================================

Animal animal = new Animal();

animal.eat()

================================

The eat() method of the Animal superclass will be called.

Explanation:

It is risky to drive while you are on drugs!

The is_positive function should return True if the number received is positive, otherwise it returns None. Can you fill in the gaps to make that happen?

def is_positive(number):

       if  _____ :

           return _____

def is_positive(number):

   if (number > 0):

       return True

  else:

       return "None"

---------------------------------------------------------------------------------

print(is_positive(6))

>> True

print(is_positive(-7))

>> None

----------------------------------------------------------------------------------

The code above has been written in Python.

Now, let's explain each of the lines of the code;

Line 1: defines a function called is_positive which takes in a parameter number. i.e

def is_positive(number):

Line 2: checks if the number, supplied as parameter to the function, is positive. A number is positive if it is greater than zero. i.e

if (number > 0):

Line 3: returns a boolean value True if the number is positive. i.e

return True

Line 4: defines the beginning of the else block that is executed if the number is not positive. i.e

else:

Line 5: returns a string value "None" if the number is not positive. i.e

return "None"

All of these put together gives;

===============================

def is_positive(number):

   if (number > 0):

       return True

   else:

       return "None"

================================

An example test of the code has also been given where the function was been called with an argument value of 6 and -7. The results were True and None respectively. i.e

print(is_positive(6))   = True

print(is_positive(-7))  = None

Following are the python program to check input number is positive or negative:

def is_positive(n):#defining the method is_positive that takes one variable in parameter

   if (n > 0):#defining if block that check input number is positive

       return True#return boolean value that is True

   else:#else block

      return "None"#return string value

n=int(input("Enter number: "))#defining n variable that input a number

print(is_positive(n))#using print method that calls and prints method return value

Answer:

C. ATA Secure Erase

D. Smash the USB drive

Explanation:

Zero fill utility is a specialized way of formatting a storage device particularly secondary storage such as hard disk, flash drive e.t.c. In this process, the disk contents are overwritten with zeros. Once this has been done, undoing is essentially hard but possible. In most cases, this might just mean that the data content is corrupt and as such might still be recovered, maybe not in its pure entirety.

Formatting the drive on another hand does not essentially mean cleaning the drive and wiping off data. It just means that operating systems cannot see those data contents anymore. They are still present in the drive and can be recovered.

ATA Secure Erase is actually a way of completely and permanently erasing the content in a drive. Once the function has been done, undoing is not possible. Both the data content and even the data management table will be completely gone.

Smashing the USB drive is the surest way of cleaning data as that will permanently destroy the working components of the drive such as the memory chip. And once that happens then there's no drive let alone its contents.

2. right below the application layer

Explanation:

TLS (Transport Layer Security) is an improved and more secured version of the SSL (Secure Socket Layer) used as cryptographic protocol for providing authentication and encryption over a network. It is initialized at the transport layer of the IP stack and finalized at the application layer. In other words, it is located between the transport and application layer of the Internet protocol stack. And this is necessary so that data received in the application layer from the transport layer are protected from start to end between these two layers.

Therefore, it is safe to say that the TLS is located right below the application layer.
