The statement is true about biometrics as an authentication method in options b and c.
<h3>What is Biometrics?</h3>
Biometrics is the measurement worried in measuring behavior or physiological traits of the human being. It is used for verifying the identification of a specific man or woman. It is probably operated in modes, particularly authentication and enrollment.
The complete question is :
Which of the following are true in biometric systems?
- a. For authentication application, a user template is compared against a single template stored in the database.
- b. For verification/identification application, a user template is compared against all the templates stored in the database.
- c. Multimodal biometrics is used to improve accuracy.
- d. None of these.
In the first mode, the facts is used and proven to test who the man or woman is. The second mode is obtaining the man or woman's facts and storing it in a database. Usually, multi-version biometrics are used for enhancing popularity accuracy.

Wouldn’t you be the one responsible since your the one taking the image?
Answer:
Check the explanation
Explanation:
#include <bits/stdc++.h>
using namespace std;
class Rectangle{
public:
int length;
int breadth;
Rectangle(int l,int b){
length = l;
breadth = b;
}
int area(){
return length*breadth;
}
int perimeter(){
return 2*(length+breadth);
}
bool equals(Rectangle* r){
// They have the exact same length and width.
if (r->length == length && r->breadth == breadth)
return true;
// They have the same area
if (r->area() == area())
return true;
// They have the same perimeter
if (r->perimeter() == perimeter())
return true;
// They have the same shape-that is, they are similar.
if (r->length/length == r->breadth/breadth)
return true;
return false;
}
};
int main(){
Rectangle *r_1 = new Rectangle(6,3);
Rectangle *r_2 = new Rectangle(3,6);
cout << r_1->equals(r_2) << endl;
return 0;
}
Answer:
a. True
Explanation:
A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user. Computers can be classified on the basis of their size and capacity as follows;
I. Supercomputers.
II. Mainframe computers.
III. Mini computers.
IV. Micro computers.
Mainframe computers were developed and introduced in the early 1950s.
Mainframe computers are specifically designed to be used for performing multi-programming because they are high-performance computers with the ability to handle multiple users. As a result, it simply means that mainframe computers can be used to effectively and efficiently perform the work of over one hundred (100) users at a time on the computer. Some examples of mainframe computers include the following; IBM Es000 series, CDC 6600 and ICL39 Series.
Furthermore, mainframe computers are mostly or commonly used by large companies, business firms or governmental institutions for performing various complex tasks such as census, financial transactions, e-commerce, data sequencing, enterprise resource planning, etc.
Answer:
c. Cloud computing
Explanation:
Cloud computing -
It refers to the on - time need of the computer resource , in order to store data , computing power by the user , is referred to as cloud computing.
It refers to the availability of the data centers to the user .
This method enables the sharing of resources .
Hence, from the information of the question,
The correct option is c. Cloud computing .
