Answer: a replay attack, a replay attack is used so that the attacker can go sniff out the hash, and get whatever they are trying to get, then once it goes to the attacker it will go back to the original connection after replaying the hash

Hackers use packet sniffing attacks to intercept or steal potentially unprotected data from networks. A network-generated threat is a sniffing attack, also known as a packet sniffing assault. Thus, option D is correct.

Snooping gives ethical hackers a lot of information about how a network functions and how its users behave, which can be used to improve a company's cybersecurity.

Sniffing can, however, be utilized by unscrupulous hackers to conduct catastrophic attacks against gullible targets.

A network sniffer can detect someone using excessive bandwidth at a college or commercial organization and hunt them down.

Therefore, replay attacks are employed so that the attacker can find the hash and obtain the desired object. Once the attacker has received the object, the replay attack causes the object to return to the original connection.

Answer:

D) Static method

Explanation:

A static method is a method that is created only for the class and not it's instance variables or objects. Such methods can only be accessed by calling them through the class's name because they are not available to any class instance. A static method is created by prefixing the method's name with the keyword static.

A static method cannot be overridden or changed. You create a static method for a block of code that is not dependent on instance creation and that can easily be shared by all instances or objects.

Answer:

The method definition to this question can be defined as follows:

int getPop(char myCode[3])//defining a method getPop that takes char array in its parameter

{

FILE* f = NULL;//defining a pointer variable

int pop;//defining integer variable

char s_code[2];//defining char array state_code

char s_name[100];//defining char array stateName

f = fopen("state", "r");//using pointer variable that use fopen method for open file

if(f == NULL)//defining if block that check file is empty

{

return -1;//return value -1

}

while(!feof(f))//defining while loop for input value in file

{

fscanf(f, "%s %s %d",s_code, s_name, &pop);//input value

if(strncmp(myCode, s_code, 2) == 0)//use if block to compare string value

{

printf("Population for %s: %d", s_name, pop);//print value

return 0;//return 0

}

}

fclose(f);//close file

return 0;

}

Explanation:

In the above code, a method "getPop" is defined that accepts a character array "myCode" in its parameter, and inside the method, one pointer variable "f", one integer variable "pop", and two char array "s_code and s_name" is declared.

In the method firstly fopen method is used that holds a file and use if block to check it is not empty, if the condition is true it will give a value that is "-1".

In the next step, a while loop is declared, that input value and use if block to compare string value, and return 0, and at the last, it closed the file.

Option 4: 50 is the correct answer.

Explanation:

Arithmetic operations can be performed using the programming languages. Some symbols used in programming languages are different from what we use in mathematics.

The symbol * is used to represent multiplication in programming languages.

B = 10

So, A*B will be equal to: 5*10 = 50

Hence,

   int array_one[n][n];

   int array_transpose[n][n];

   for (int i = 0; i < n; i++){

           array_transpose[j][i] = array_one[i][j];

       }

Explanation:

The C source code has three variables, 'array_one', array_transpose' (both of which are square 2-dimensional arrays), and 'n' which is the row and column length.

The program loops n time for each nth number of the n size to assign value to the two-dimensional array_one. the assign values to the array_transpose, reverse the 'i' and 'j' values to the two for statements for array_one to 'j' and 'i'.

C. Doesn't make any sense

D. Complete Garbage

Answer:

- Iterate over the Bellman-Ford algorithm n-1 time while tracking the parent vertex and store in an array.

- Do another iteration and if no relaxation of the edges occurs in the nth iteration then print of return "There are no negative cycle".

- Else, store the vertex of the relaxed edge at the nth iteration with a variable name.

- Then iterate over the vertexes starting from the store vertex until a cycle is found then print it out as the cycle of negative weight.

Explanation:

The Bellman-Ford algorithm can be used to detect a negative cycle in a graph. The program should iterate over the algorithm, in search of a relaxed edge. If any, the vertex of the specified edge is used as a starting point to get the target negative cycle.

Explanation:

SQL or structured query language is a database querying language used to communicate or interact with databases. A database query could be as simple as returning all the columns from a database table to complex like joining several query results which in turn forms an algebra expression.

Every query statement or expression is executed with time, execution time needs to be minimized for efficiency, so, a well-arranged and reduced joining in the query improves the efficiency of the query.

We start from the bottom-most and rightmost internal node of min Heap and then heapify all internal modes in the bottom-up way to build the Max heap.

To build a heap, the following algorithm is implemented for any input array.

BUILD-HEAP(A)

   heapsize := size(A)

   for i := floor(heapsize/2) downto 1

       do HEAPIFY(A, i)

   end for

Convert the given array of elements into an almost complete binary tree.

Ensure that the tree is a max heap.

Check that every non-leaf node contains a greater or equal value element than its child nodes.

If there exists any node that does not satisfy the ordering property of max heap, swap the elements.

Start checking from a non-leaf node with the highest index (bottom to top and right to left).

   else:

       print(f"the word {word} is a negative word with review\

{round(np.mean(acc), 2)}")

Explanation:

The python program gets the text from the review file, using the user input word to get the definition of reviews based on the word, whether positive or negative.

The program uses the 'with' keyword to open the file and created the acc variable to hold the reviews gotten. The mean of the acc is calculated with the numpy mean method and if the mean is equal to or greater than 2 it is a positive word, else negative.

Vector graphics consist of mathematical descriptions of shapes as a combination of these numerical vectors. Because the vector graphics define the path that the lines should take, rather than a set of points along the way, they can be used to calculate any number of points, and so can be used at any image resolution.

The characteristics of vector graphics are they are based on mathematical/geometric expression. The correct option is A.

Vector graphics are mathematical descriptions of shapes created by combining these numerical vectors. Because vector graphics indicate the course that the lines should travel rather than a set of locations along the way, they may be used to calculate any number of points and thus work at any image resolution.

Raster images generate commonly used image files such as gif, jpeg, jpg, and so on. These can be made with picture editing software such as "Photoshop." Because these work on pixels, when we zoom the image, we can see tiny squares that are nothing more than pixels.

Therefore, the correct option is A, they are based on mathematical/geometric expression.
