.Why are protocols important for networking?

1 answer:

6 0

Answer: Networking protocols are important as they define a set of rules to be used for exchanging information between computer nodes.

Explanation:

in terms of networking it is required for the source and the destination to have a set of predefined rules which enables the router to send and receive information across the network in such as way that both the ends are able to receive the messages.

The information exchange takes place first by the client by introducing itself to the remote server. the remote server upon receiving the information uses some form of handshaking and acknowledges the client of the receipt of the message.

besides this there are many routing protocols which tells us about the way how packets are sent from the client to the source. There are two types of routing protocols:

1. static routing protocols

2. dynamic routing protocols.

Hit and Slopes Program: A Write a program that can be used by a ski resort to keep track if local snow conditions for one week.

Llana [10]

Answer:

The java program is as follows.

import java.lang.*;

import java.util.Scanner;

public class Main

{

//array declaration

static int weekdays=7;

static int[] snowfall_inch = new int[weekdays];

static String[] snowfall_date = new String[weekdays];

//variables to store average and maximum

static double avg;

static int max;

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Enter the month: ");

String month = sc.next();

for(int n=0; n<weekdays; n++)

{

System.out.print("\nEnter the date for day "+(n+1)+ ": ");

snowfall_date[n] = sc.next();

System.out.print("Enter the inches of snowfall for day "+(n+1) +": ");

snowfall_inch[n] = sc.nextInt();

avg = avg + snowfall_inch[n];

}

avg = avg/weekdays;

System.out.printf("The average snowfall for the week is %.4f",avg);

for(int n=0; n<weekdays-1; n++)

{

if(snowfall_inch[n] < snowfall_inch[n+1])

max=snowfall_inch[n+1];

}

System.out.println("\nThe maximum snowfall for the week is "+max);

}

OUTPUT

Enter the date for day 2: 12-2-2019

Enter the inches of snowfall for day 2: 23

Enter the date for day 3: 12-3-2019

Enter the inches of snowfall for day 3: 13

Enter the date for day 4: 12-4-2019

Enter the inches of snowfall for day 4: 14

Enter the date for day 5: 12-5-2019

Enter the inches of snowfall for day 5: 34

Enter the date for day 6: 12-6-2019

Enter the inches of snowfall for day 6: 34

Enter the date for day 7: 12-7-2019

Enter the inches of snowfall for day 7: 22

The average snowfall for the week is 21.7143

The maximum snowfall for the week is 34

Explanation:

1. Two arrays are declared to store dates and snowfall inches with string and integer datatypes respectively.

2. Variables are declared to store maximum and average snowfall values with integer and double datatypes respectively.

3. User input is taken for the month, and the dates and snowfall inch values for a week. The input is taken in for loop.

4. Next, for loop is used to find the average and maximum snowfall of the week.

5. These values are displayed to the user as shown in the output.

Var faceS = 100; var mouthS = 30; ellipse(200, 200, faceS, faceS); ellipse(200, 220, mouthS, mouthS); How wide is the second ell

kenny6666 [7]

The first two parameters of the ellipse function are the beginning x and y coordinates. The last two are the width and height of the ellipse. The second ellipse starts at (200px, 200px) and has a width and height equal to mouthS. We are given mouthS as 30, therefore the mouth is 30 pixels wide.
