Answer:
RFID scanning or Barcode reader
Explanation
Smart refrigerators have inbuilt RFID scanning technology that help monitor the stock that is inside your fridge. Once you pass your items through the inbuilt RFID scanner in the fridge, the barcode of your items is cross-referenced with a database and given a unique tag for identification. This technology helps detect and track the stock that is inside your fridge and when you start running low, the RFID can be triggered to send a reminder as a notification on your email or a text message.
Answer:
Tags can be identified as they are written as <tagname> Something </tagname>
<tagname> this tag is called start tag.
</tagname> this tag is called as end tag.
for ex:<p> This is a paragraph </p>
There are some elements with no end tag.for ex:- <br> tag.
Attributes are used to provide additional information to an HTML element.
Every element can have attributes.
for Ex:- <h1 style="background-color:red";>MY WEBSITE </h1>
So the background of h1 will become red.

Answer:
The output of the given code as follows:
Output:
Area is: 12.60676
Explanation:
In the given code some information is missing so, the correct code to this question can be described as follows:
Program:
public class Test //defining class
{
public static void main(String[] args)//defining the main method
{
double radius= 2; //defining double variable radius
final double PI= 3.15169; //defining double variable PI
double area = radius * radius * PI; //defining double variable area that calculates values
System.out.println("Area is: " + area); //print values
}
}
Explanation:
- In the given java code a class "Test" is defined, in which a double variable "radius" is defined, which holds a value, that is 2.
- In the next step, a double constant variable, that is PI is defined, that holds a value, that is "3.15169".
- Then another double variable area is defined, that calculates the area value, and prints its value.
