The Open Systems Interconnection (OSI) is a conceptual model whose purpose is to make networks more manageable. Its objectives i

nclude allowing for more portable hardware and software integration, the creation of standard interfaces that would allow manufacturers of different systems to interconnect their equipment and the creation of a model that would be used world-wide. There are seven layers to the OSI. The lowest - or first - layer allows a contiguous sequence of bits to be transmitted through the network. Which is the first layer: A. data-link layer, B. physical layer, C. network layer, D. transport layer

Answer:

A. data-link layer

Explanation:

Data-link layer is the first layer and allows a contiguous sequence of bits to be transmitted through the network.

On top of it is the Network Layer and it handles the task of routing network messages from one computer to another.

Then comes the Transport Layer which is the basic layer at which one network computer communicates with another network computer.

tekilochka [14]

Answer:

The following are the program to the given question:

import java.util.*;//import package for user input

public class Make  //define class Make

{

public static void main(String[] ask)  //define a main method

{

  Scanner obx = new Scanner(System.in);   //declare the Scanner class object

  int size=obx.nextInt(); //get the size of the array from the user

  int a[]=new int[size]; //declare an integer array with given size

  String word[]=new String[size]; //declare a string array with given size

  for(int i=0;i<size;i++) //set the for loop  

  word[i]=obx.next(); //get string input from the user

  for(int i=0;i<size;i++)   //iterates with the array, increase the count

  {

    for(int j=0;j<size;j++)   //defining a loop to check value

    {

      if(word[i].equals(word[j]))  //use if to check that elements of words          

      a[i]++;//increamenting array size

    }

  }

 System.out.print("\n");  //use print for break line  

  for(int i=0;i<size;i++)//set for loop to print the following result

    System.out.println(word[i]+" "+a[i]);//print value

 }

}

Output:

Please find the attachment file.

Explanation:

  • First, establish the predefined package required and instead define the main class and define the main method within the class and method.
  • Declare the scanner class object and receive an object size in the 'size' variable thru the array.
  • Next create two arrays, the integer type "a" with both the input size given and the string type "word" with the input size supplied.
  • Define the loop for which string array elements are acquired and set two to again for loop, which increases with loop iteration the integer data type array by one.
  • Lastly, set the loop for which this result is printed.
