Answer:
3.WDM
Explanation:
WDM ( wavelength division multiplexing ) involves signals composed of light beams WDM is used in communication where fibers are used it is used for multiplexing of number of carrier signals which are made of optical fibers by using different wavelength of laser light it has different wavelength so this WDM is used for signals composed of light beams it has property of multiplexing of signal
Answer:
Technology refers to methods, systems, and devices which are the result of scientific knowledge being used for practical purposes. Technology is changing fast. They should be allowed to wait for cheaper technologies to be developed.
Concatenation, which mean we combine two or more strings into one.
Answer:
import java.util.Scanner;
public class num10 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter the numbers to add up. enter 999 to stop");
int num = in.nextInt();
int sum = 0;
while (num!=999){
sum = sum+num;
System.out.println("Enter the next number");
num = in.nextInt();
}
System.out.println("The sum is: "+sum);
}
}
Explanation:
The application is implemented in Java
A while loop is used to continously prompt user for inputs. The condition of the while loop is while (num!=999)
When the number 999 is entered, it displays the sum which is initialized to 0
Answer:
b. selection sort
b. 8 11 17 30 20 25
Explanation:
The options above are the correct answers to the given questions.
Selection sort is a simple comparison-based sorting algorithm.
selection sort. (algorithm) Definition: A sort algorithm that repeatedly searches remaining items to find the least one and moves it to its final location. The run time is Θ(n²), where n is the number of elements. The number of swaps is O(n).
It is this sorting algorithm that will best ne suitable in the given event.
