What technique creates different hashes for the same password? ccna routing protocols final answers?

elena-s [515]

The answer is Salted Password Hashing. The process is similar to hashing., but with a twist. A random value is introduced for each user. This salt value<span> is included with the password when the hash value is calculated and is stored with the user record. Including the salt value means that two users with the same password will have different password hashes.</span>

Write a method called makeStars. The method receives an int parameter that is guaranteed not to be negative. The method returns

serious [3.7K]

Answer:

// import the Scanner class

// to allow the program receive user input

import java.util.Scanner;

// The class Solution is defined

public class Solution{

// main method to begin program execution

public static void main(String[] args) {

// scanner object scan is declared

Scanner scan = new Scanner(System.in);

// Prompt the user to enter a number

System.out.println("Enter the number of stars you want: ");

// user input is assigned to numOfStar

int numOfStar = scan.nextInt();

// call the makeStars method

makeStars(numOfStar);

}

// makeStars method print stars using recursion

// the method call itself till starNum == 0

public static void makeStars(int starNum){

if (starNum != 0){

System.out.print("*");

makeStars(starNum -1);

}

Explanation:

The code is well comment and solve the problem using recursion.

A computer has 4 GB of RAM of which the operating system occupies 512 MB. The processes are all 256 MB (for simplicity) and have

Afina-wow [57]

Answer:

$1-p^{14} = 0.99$

$p^{14}= 0.01$

$p =(0.01)^{1/14}= 0.720$

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %

Explanation:

Previous concepts

Input/output operations per second (IOPS, pronounced eye-ops) "is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD)"

Solution to the problem

For this case since we have 4GB, but 512 MB are destinated to the operating system, we can begin finding the available RAM like this:

Available = 4096 MB - 512 MB = 3584 MB

Now we can find the maximum simultaneous process than can use with this:

$\frac{3584 MB}{256 MB/proc}= 14 processes$

And then we can find the maximum wait I/O that can be tolerated with the following formula:

$1- p^{14}= rate$

The expeonent for p = 14 since we got 14 simultaneous processes, and the rate for this case would be 99% or 0.99, if we solve for p we got:

$1-p^{14} = 0.99$

$p^{14}= 0.01$

$p =(0.01)^{1/14}= 0.720$

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %

A city government is attempting to reduce the digital divide between groups with differing access to computing and the Internet.

sergeinik [125]

Answer:

C

Explanation:

Putting all government forms on the city web site is the least activity likely to be effective in the purpose of reducing digital divide.

Holding basic computer classes at the community centers will very much help to reduce the digital divide.

Providing free wireless internet connections at locations in low-income neighborhood will also reduce the gap of digital divide

Requiring that every city school has computers that meet a minimum hardware and software will made computing resources available to users thereby reducing digital divide.
