Its use of the message digest 5 (MD5) hash algorithm for security.

CHAP uses a combination of MD5 hashing and a challenge-response mechanism, and authenticates without sending passwords as plaintext over the network. The security of the MD5 hash function is severely compromised.

Given a typical magnetic hard drive with five platters, answer the following:

Nataly_w [17]

Answer:

Given the number of platters =5

A. Hence, the number of recording surface =10

B. number of read-write heads =10

C. Number of arms holding the read-write heads = 10

Explanation:

We know that number of recording surface = 2 *( number of platters)

= 2*5=10

And the number of read-write heads = number of recording surface= 10

Also, number of arms holding the read-write head = one for each read-write head= 10

And hence, the above answer.

Write a program that prompts the user for the lengths of the two legs of a right triangle, and which reports the length of the h

timurjin [86]

Answer: The following code is in c++

#include <iostream>

#include<math.h>

using namespace std;

int main()

{

float a,b,c;

cout<<"Enter height and base of triangle\n";

cin>>a>>b; //reading two sides from user

c=sqrt(pow(a,2)+pow(b,2)); //calculating hypotenuse

cout<<"Length of hypotenuse is "<<c; //printing third side of triangle

return 0;

}

OUTPUT :

Enter height and base of triangle

Length of hypotenuse is 5

Explanation:

In the above code, three variables a, b and c of int type are declared. After that, it is asked from user to enter the value of a and b. The user puts the value and then c is calculated with the help of Pythagoras theorem formulae which squares the values of two sides and then adds them to calculate hypotenuse of a right angled triangle and finally c is printed to console.

double salary;

double salaryToHome;

double Federal_Tax,TAX_RATE,Depen_tax;

Payroll(double salry,int nod)

{

TAX_RATE=28.0;

Depen_tax=2.5;

}

double getTAX_RATE()

{

return TAX_RATE*salary/100;

}

double Federal_Tax()

{

return Federal_Tax*salary/100;

}

double getDepenAmount()

{

return numOfDependents*(Depen_tax*salary/100);

}

double getTakeHomeSalary()

{

return salary+getDepenAmount()-(getTAX_RATE()+Federal_Tax());

}

void printOutput()

{

System.out.print("\nState Tax: $"+getTAX_RATE());

System.out.print("\nFederal Tax: $"+Federal_Tax());

System.out.print("\nDependents: $"+getDepenAmount());

System.out.println("\nTake Home Pay: $"+getTakeHomeSalary());

}

public static void main(String args[])

{

Payroll obj=new Payroll(1250,2);

obj.printOutput();

}

// ModifiedPayroll.java

import java.util.Scanner;

}

double getTAX_RATE()

{

return TAX_RATE*salary/100;

}

}

double getDepenAmount()

{

}

double getTakeHomeSalary()

{

return salary+getDepenAmount()-(getTAX_RATE()+Federal_Tax());

}

void printOutput()

{

System.out.print("\nState Tax: $"+getTAX_RATE());

System.out.print("\nFederal Tax: $"+Federal_Tax());

}

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.print("\nEnter Salary: $");

double salary=sc.nextDouble();

System.out.print("\nEnter number Of Dependents:$");

int nob=sc.nextInt();

ModifiedPayroll obj=new ModifiedPayroll(salary,nob);

obj.printOutput();

}

Explanation/Output:

// For Payroll.java

State Tax: $350.0

Federal Tax: $81.25

Dependents: $62.5

Salary: $1250.0

Take Home Pay: $881.25

// For ModifiedPayroll.java

Enter Salary:$1550.0

Enter number of Dependents:$3

State Tax: $434.0

Federal Tax: $100.75

Dependents: $116.25

Salary: $1550.0

Take Home Pay: $1131.5
