Answer:
Option A (Radio Frequency Identification)
Explanation:
Option A (Radio Frequency Identification)
Radio Frequency Identification:
This technology uses radio waves to transfer data between a reader and movable items. The benefit of this technology is we do not require physical contact with items and scanner.
Components of RFID:
There are two RFID standards:
B. contiguous signals
C. ramp signals
D. exponential signals
Answer: A) Digital signals
Explanation:
Answer:
i think digital signals
Explanation:
A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on one of a finite number of values.[1][2][3] This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.
Answer:
import java.util.Scanner;
public class num9 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter year");
int givenYear =in.nextInt();
if(givenYear>=2101){
System.out.println("Distant Future");
}
else if(givenYear>=2001){
System.out.println("21st Century");
}
}
}
Explanation:
B. Quantitative risk assessment
C. Qualitative assessment of risk
D. Business impact scoring
E. Threat modeling
Answer:
The correct answer to the following question is option B). Quantitative risk assessment.
Explanation:
QRA ( Quantitative Risk assessment) is the objective risk assessment tool that is used to project threat impacts.
Quantitative Risk Assessment provides the estimate of magnitude of the consequences for each of the identified budget threats.
It set out to measure, define, provide, and predict the confidence level of the likelihood and the occurrence of the threat impacts.

Answer:
The constructor are executed when the constructor object are comes in the existence as per the general rule in the computer programming language. The constructor is the special type of the class function that basically perform the initialization of the each object in the computer science.
Then, the constructor initialized actual value of the member of an object are allocated to the given object in the system.
