The acronym RFID (Radio Frequency Identification) describes
networked devices that contain microcomputers but are not thought of as
computing devices, such as refrigerators, automobile components, light
bulbs, and industrial control devices. RFIDs are battery-powered sensors that gather and transmit data to a reading device. Some sensor based technologies are scanning electron microscopes, LiDAR,radar, GPS, x-ray, sonar, infrared and seismic.
Answer:
The Variable is out of scope
Explanation:
In programming variables exists with scopes This could be local or global. When a variable is declared as a global variable it is available to all methods and procedures in the program. Java programming language as well as C++ and several others use the open and close braces to define the scope in programs. consider the following example
<em>public class ANot {</em>
<em> public static void main(String[] args) {</em>
<em> int i = 0;</em>
<em> while ( i<10){</em>
<em> int sum = 0;</em>
<em> sum = sum+i; </em>
<em> }</em>
<em> }</em>
<em>}</em>
In this example, the variable i is global and can be assessed within the while loop but the variable sum is local to the while loop and cannot be assessed outside of it

Answer:
b. data type of arguments
Explanation:
One of the ways to overload a method is using different type of arguments. Let's say we have a method that finds and returns two integer values
public int sumValues(int num1, int num2){
return num1 + num2;
}
We can overload this method by passing double values as arguments
public double sumValues(double num1, double num2){
return num1 + num2;
}
