Answer:

D: A single direct connection is established between any two devices connected to the Internet.

Explanation:

The internet is a complex network system made of protocols, packets, and other things. For a network to be connected, it requires the use of multiple pathways. It is unnecessary for a single direct connection because of most of the networks in this real-world travel in multiple direct connections. For example, if you want to go to Brainly.com. It first needs your IP address and then the protocols like HTTP and TCP to send it. Networks are just like traffic. If one section or a part gets blocked, they go on a different path and reach their destination. It is the same here for networks. Networks go into multiple directions to get to their destination. Therefore, a single direct connection is not required or necessary to make it possible.

tiny-mole [99]

Answer:

  1. import java.util.Scanner;
  2. public class Main {
  3.    public static void main (String [] args) {
  4.        int jersey_num [] = new int[5];
  5.        int rating [] = new int[5];
  6.        Scanner inStream = new Scanner(System.in);
  7.        for(int i=0; i < 5; i++){
  8.            System.out.print("Enter player " + (i+1) + "'s jersey number:");
  9.            jersey_num[i] = inStream.nextInt();
  10.            System.out.print("Enter player " + (i+1) + "'s rating:");
  11.            rating[i] = inStream.nextInt();
  12.        }
  13.        System.out.println("ROSTER");
  14.        for(int j=0; j < 5; j++){
  15.            System.out.println("Player " + (j+1) + "-- Jersey number: " + jersey_num[j] + ", Rating: " + rating[j]);
  16.        }
  17.    }
  18. }

Explanation:

The solution code is written in Java. Firstly create two array, jersey_num and rating, with int type. This is to hold the five pairs of numbers input by user (Line 6 -7).

Next, create a for loop that run for 5 iterations and in each iteration prompt user to input jersey number and rating (Line 11 -17). The input number and rating will be set to the array, jersey_num and rating, respectively.

Next, print the title "Roster" (Line 19).

Create another for loop to display the five input pair of values (Line 21 - 23).
