Is a ROUTER required for Internet Connectivity ?<br> Yes<br> No

Use the Internet and other sources to research the two disadvantages of standard biometrics: cost and error rates. Select one st

lyudmila [28]

Answer:

Check the explanation

Explanation:

Selecting the bio-metric technique fingerprint, it requires a scanner to read the fingerprint The cost for a scanner is in between 1000 and 5000 Placing two scanners at two entrance of office win cost bellow 10,000 So the cost needed for this technique is medium as compared with other bio-metric techniques

Attacks on this technique can be in saner, channel from scanner to feature extractor, in feature extractor, way in between feature extractor and marcher, in marcher, in database etc this attacks can be protect by using security methods such as cryptography, hashing, watermarking, noses etc

By using watermarking, cryptography and stenography methods, fingerprint has less false detection rate I e it gives high accuracy

I recommend fingerprint technique. Because of it is a standard technique, it has good accuracy and cost is less, and easy to handle, and it is taking small storage space in database.

Write a program that asks the user for three strings. Then, print out whether the first string concatenated to the second string

zepelin [54]

Answer:

import java.util.Scanner;

public class Main {

public static void main(String[] args) throws Exception {

Scanner myObj = new Scanner(System.in);

//Request and receive first String

System.out.println("Enter username");

String firstString = myObj.nextLine();

//Request and receive second string

System.out.println("Enter second string");

String secondString = myObj.nextLine();

//Request and receive third string

System.out.println("Enter third string");

String thirdString = myObj.nextLine();

//Concatenate the first and second string

String concatA_B = firstString + secondString;

if(concatA_B.equals(thirdString)){

System.out.println("First String Concatenated to Second String is equals to the third String");

}

else{

System.out.println("First String Concatenated to Second String is NOT equals to the third String");

}

Explanation:

Import Scanner Class
Request and Receive three variables from the user using the Scanner Class
Concatenate the first and second
Use the .equals() method to check for equality

What is the voltage drop across R4 in the diagram shown above?

pickupchik [31]

R₂ and R₃ can be replaced by:

$R_5 = \frac{1}{\frac{1}{R_2} + \frac{1}{R_3}} = 106 \frac23$

The total R of the circuit is R₁+R₅+R₄ = 706 2/3

So the current in the circuit I=V/R is 100/(706 2/3) = 15/106 A
(I'm deliberately not trying to round the result)

The voltage drop over R₄ is V=I*R = 15/106 * 500 ≈ 70

So answer C would be my choice.
