Suppose the length of each packet is L bits. Also, assume the path from a server to a client includes N links each of rate R (i.

e., there are N-1 routers between the server and the client).a. With store-and-forward packet switching, what is the end-to-end delay to transmit one packet over the N links (ignoring propagation, processing, and queueing delays)?b. What is the delay if the server sends P such packets back-to-back over the N links?

Every preprocessing directive must begin with:
Anni [7]

Answer:

B. #

Explanation:

Every preprocessing directive must begin with the # character.

For example:

#define : Used to define a macro

#ifndef : Conditional evaluation of macro

#include : Used to include other preprocessor header file as part of the code

As we can see each of the directives begins with the # character. This is a signal to the preprocessor to interpret the subsequent keyword as a directive.

Lady_Fox [76]

Answer:

Check the explanation

Explanation:

// include the necessary packages

import java.io.*;

import java.util.*;

// Declare a class

public class DataReader

{

// Start the main method.

public static void main(String[] args)

{

// create the object of scanner class.

Scanner scan = new Scanner(System.in);

// Declare variables.

boolean done = false;

boolean done1 = false;

float sum = 0;

double v;

int count = 0;

// start the while loop

while (!done1)

{

// start the do while loop

do

{

// prompt the user to enter the value.

System.out.println("Value:");

// start the try block

try

{

// input number

v = scan.nextDouble();

// calculate the sum

sum = (float) (sum + v);

}

// start the catch block

catch (Exception nfe)

{

// input a character variable(\n)

String ch = scan.nextLine();

// display the statement.

System.out.println(

"Input Error. Try again.");

// count the value.

count++;

break;

}

}

// end do while loop

while (!done);

// Check whether the value of count

// greater than 2 or not.

if (count >= 2)

{

// display the statement on console.

System.out.println("Sum: " + sum);

done1 = true;

}

}

}

}

Sample Output:

Value:

12

Value:

12

Value:

ten

Input Error. Try again.

Value:

5

Value:

nine

Input Error. Try again.

Sum: 29.0
