During the data transmission there are chances that the data bits in the frame might get corrupted. This will require the sender

to re-transmit the frame and hence it will increase the re-transmission overhead. By considering the scenarios given below, you have to choose whether the packets should be encapsulated in a single frame or multiple frames in order to minimize the re-transmission overhead.
Justify your answer
Scenario A: Suppose you are using a network which is very prone to errors.

Scenario B: Suppose you are using a network with high reliability and accuracy.

1. Based on Scenario A, the packets should be encapsulated in multiple frames to minimize the re-transmission overhead.

This is because there will be the need to re-transmit the packets because the network environment is not reliable and accurate.  Therefore, a single frame may be too costly when the need for re-transmission arises.

2. Based on Scenario B, the packets should be encapsulated in a single frame because of the high level of network reliability and accuracy.  

There will not be further need to re-transmit the packets in a highly reliable and accurate network environment.  This environment makes a single frame better.

Encapsulation involves the process of wrapping code and data together within a class so that data is protected and access to code is restricted.

With encapsulation, each layer:

  • provides a service to the layer above it
  • communicates with a corresponding receiving node

Thus, in a reliable and accurate network environment, single frames should be used to enhance transmission and minimize re-transmission overhead.

X = 9 % 2if (x == 1):  print ("ONE")else:  print ("TWO")
IgorC [24]

Answer:

ONE

Explanation:

It prints one because % is modulus, which is remainder division. It divides the numbers provided and returns the remainder of the division. 9 / 2 = 4 with 1 remainder, which leads us to our answer.

Marina86 [1]

Answer:

I am writing a C++ and JAVA program.    

import java.util.Scanner; //for using input output functions

public class LabProgram { // class name

public static void main(String[] args) {//start of main function body

Scanner input = new Scanner(System.in);

// creates input instance of  Scanner type

     String str;  // declares String type variable str for a string value

     int num;  // declares integer type variable num to hold an integer value

     str = input.next(); //scans and reads input string from user

     num = input.nextInt();  //scans and reads input integer from user

//while loop continues to execute until user enters quit 0

while(str!="quit" && num!=0) {  

/* prints the following message, for example if value of num = 2 and value of str = apples then the following print statement prints Eating 2 apples a day keeps the doctor away. */

System.out.println("\nEating " + num +" " + str + " a day keeps the doctor away.");

//takes string and integer as input again and keep taking input until user //enters quit 0

str = input.next();  

num = input.nextInt(); }   } }

Explanation:

The program is well explained in the comments mentioned with each statement of the program. The program simply prompts user to enter a string and an integer. The while loop keeps executing until user enters quit 0. The program keeps taking input string and integer from user and prints the message System.out.println("\nEating " + num +" " + str + " a day keeps the doctor away.");  The loop breaks when the use enters quit 0. The screenshot of the program along with its output is attached.
