Answer:
The process of converting information, such as text, numbers, photos, or music, into digital data that can be manipulated by electronic devices is called Digitization
Explanation:
It is the process of converting “information in to a digital form”. Here the information are organized into bits. Mostly these data will be converted into the form of image. But these can be edited by converting once again into necessary format and even back to image too. There are specific tools which the user needs to install for editing the digital documents.
The reason why we need digitization is that
a) We want to convert hard copy into soft copy and store it in system.
b) We would like to edit the data in the hard copy and preserve as a fresh copy.
Answer:
import java.util.Scanner;
class Main {
public static void main(String args[]) {
Scanner scan = new Scanner(System.in);
System.out.print("Enter a decimal value (0 to 15): ");
int num = scan.nextInt();
scan.close();
if (num < 0 || num >15) {
System.out.printf("%d is an invalid input\n", num);
} else {
System.out.printf("The hex value is %X\n", num);
}
}
}

Hopefully this example will get you going for the other assignments.
Answer:
- <u>1,000W</u> (rounded to one significant figure)
Explanation:
I will answer in English.
The question is:
- <em>What is the power of a filament lamp that connects to the 220 V network, knowing that it has a resistance of 50 ohms?</em>
<em />
<h2>Solution</h2>
<em />
<em>Power</em>, <em>voltage</em>, <em>resistance</em>, and current, are related by either of the following equations:
Where:
- R is resistance in ohms (Ω)
- V is voltage in volts (V), and
- I is current in amperes (A)
Since you know the voltage (<em>220V</em>) and the resistance (<em>50Ω</em>), you can use the last equation:
Since the magnitude 50Ω has one significant figure, your answer should be rounded to one significant figure. That is <u>1,000W.</u>
Answer: I a reference to the next node
III a data element
Explanation:
A linked list is simply referred to as a linear data structure, whereby the elements would not be stored at memory locations that are together in the sequence.
In simple words, we can simply say that a linked list is made up of nodes in which, every node has a data element and also a link or reference to the next node that is in the list.
Therefore, based on the explanation above, the correct option will be:
I. a reference to the next node
III a data element
