Answer:
Using a one time password OTP and using a three factor authentication.
Explanation:
Social engineering is a form system and network attack, drafted by an attacker, to steal user credentials needed for accessing their accounts, to steal information.
Social engineering attacks like phishing, spear phishing, baiting and quid quo pro are used to fool users to giving out their user details.
One time password is an implied use of a password just once and a new password his generated to boost security. In a three factor authentication, OTP can be used as well as biometrics of a user which can not be giving away by a user to an attacker.
Answer:
FALSE
Explanation:
The exit function is used to terminate or halt the process.
Syntax-
void exit(int status)
Exit function (exit()) can be used in any function not only main() and it will terminate your whole process.
<u></u>
<u>Example-</u> C Program
#include<stdio.h>
#include <stdlib.h>
// function declaration
float exitexample ( float x );
// Driver program
int main( )
{
float a, b ;
printf ( "\nEnter some number for finding square \n");
scanf ( "%f", &a ) ;
// function call
b = exitexample ( a ) ;
printf ( "\nSquare of the given number %f is %f",a,b );
/*This will not printed as exit function is in exitexample() function*/
}
float exitexample ( float x ) // function definition
{
exit(0); //exit function
float p ;
p = x * x ;
return ( p ) ;
}
Answer:
The answer is "ICANN"
Explanation:
In the given question some information is missing, that is option, which can be described as follows:

- IAB, It provides a protocol to manage IETF, that's why it is wrong.
- W3C is used in web development.
- ISOC is used to provide internet accessibility.
Answer:
while(userNum>=1){
System.out.print(userNum/2+" ");
userNum--;
}
Explanation:
This is implemented in Java programming language. Below is a complete code which prompts a user for the number, receives and stores this number in the variable userNum.
<em>import java.util.Scanner;</em>
<em>public class TestClock {</em>
<em> public static void main(String[] args) {</em>
<em> Scanner in = new Scanner (System.in);</em>
<em> System.out.println("Enter the number");</em>
<em> int userNum = in.nextInt();</em>
<em> while(userNum>=1){</em>
<em> System.out.print(userNum/2+" ");</em>
<em> userNum--;</em>
<em> }</em>
<em> }</em>
<em>}</em>
The condition for the while statement is userNum>=1 and after each iteration we subtract 1 from the value of userNum until reaching 1 (Hence userNum>=1)
