Answer:

Rainbow table attack

Explanation:

A rainbow table attack is a type of network attack or hacking where the hacker tries to utilize a rainbow hash table to crack the passwords in a database system. A rainbow table itself is a hash function used in cryptography for saving important data in a database. Especially passwords.

In this process, sensitive data are hashed two or multiple times with the same key or with different keys so as to avoid rainbow table attack. In a rainbow table attack, the hacker simply compares the hash of the original password against hashes stored in the rainbow table and when they find a match, they then identify the password used to create the hash.

mafiozo [28]

Answer:

Following are the code to this question:

#include<iostream>//import header file

using namespace std;

int main()//defining main method

{

int ar[7];//defining 1_D array that stores value

int i,x=0,l1=1,j; //defining integer variable

for(i=0;i<7;i++)//defining for loop for input value from user ends

{

cout<<"Enter a Number: ";//print message

cin>>ar[i];//input value in array

if(l1<=2 && i>0)//using if block that checks the array values

{

x++;//increment the value of x by 1

}

if(l1>2 && i>0)//using if block that checks the array values

{

l1=l1-2;//using l1 variable that decrases the l1 value by 2

}

j=i-x;//using j variable that holds the index of the root of the subtree

if(i>0 && ar[j]>ar[i])// use if block that checks heap condition

{

l1++; //increment the value of l1 variable

}

if(i>0 && ar[j]<ar[i])// using the if block that violate the heap rule

{

cout<<ar[i]<<" "<<"Violate the heap";//print message with value

break;//using break keyword

}

return 0;

}

Output:

Enter a Number: -15

Enter a Number: -5

-5 Violate the heap

Enter a Number: 45

Enter a Number: 0

Enter a Number: 55

55 Violate the heap

Explanation:

In the above-given C++ language code, an array "ar" and other integer variables " i,x,l1, j" is declared, in which "i" variable used in the loop for input values from the user end.
In this loop two, if block is defined, that checks the array values and in the first, if the block it will increment the value of x, and in the second if the block, it will decrease the l1 value by 2.
In the next step, j variable is used that is the index of the root of the subtree. In the next step, another if block is used, that checks heap condition, that increment the value of l1 variable. In the, if block it violate the heap rule and print its values.

What usually happens at a police check? Do they just look up your name in their system?

sdas [7]

it depends on the kind of police check. like if its a road block type of check, they make sure everything is right. if you get pulled over you get your name ran in the system to check if you have warrents or warning and depends on what you get pulled over for, you could get a ticket or detained.

Piecewise functions are sometimes useful when the relationship between a dependent and an independent variable cannot be adequat

Andru [333]

Answer:

//Set a piecewise function v(t).

function v = vpiece(t)

//Set the condition first for t.

if ((0<=t)and(t<=8)) //Set if condition

// first equation of velocity.

v = 10*t^2 - 5*t;

//Set the condition second for t.

elseif((8<=t)and(t<=16)) //Set elseif condition

//second equation of velocity.

v = 624 - 5*t;

//set the condition third for t.

elseif((16<=t)and (t<=26)) //Set elseif condition

//third equation of velocity.

v = 36*t + 12*(t - 16)^2;

//Set the fourth condition for t.

elseif t>26

//fourth equation of velocity.

v = 2136*exp(-0.1*(t-26));

//Last condition.

else

//fifth equation of velocity.

v = 0;

//End of the function v.

end

//set a variable and initialize it to 0.

a=0;

//Starting the loop.

for j = -5: 0.5 : 70

//Increment the value of a by 1.

a = a + 1;

t(a) = j;

v(a) = vpiece(t(a));

//End of for loop.

end

//Plot the graph between t and v.

plot(t,v)

//Write the label for the x-axis.

xlabel('t')

//Write the label for the y-axis.

ylabel('velocity')

//Write the title of the plot.

title('Plot of velocity vs t')

Explanation:

Firstly, we set the piecewise method.

Then we set the first condition, after that we apply the condition of velocity.

Then we set the second condition, after that we apply the condition of velocity.

Then we set the third condition, after that we apply the condition of velocity.

Then we set the fourth condition, after that we apply the condition of velocity.

Then we set the last or fifth condition, after that we apply the condition of velocity.

Then we set the variable "a" to 0.

Then start the loop and increase the value by 1.

And after all, we write the title of the plot.

AUPs ensure that an organization’s network and internet are not abused. Select 3 options that describe AUPs.

tigry1 [53]

AUPs often involves not going onto unauthorized sites or downloading certain content, not using the service to violate any law, and not connecting to unauthorized devices through the network.

AUP stands for Acceptable Use Policy, which refers to a policy that regulates users when they access a corporate newtork.

<h3>How does an AUP regulates users?</h3>

Most AUPs imply:

Users can only access certain sites and dowloading specific content is forbidden.
The access to the internet or network cannot be used for criminal purposes.
Only authorized users can connect to the corporate network.
