"Explain the functionality of the different layers found in the network protocol stack of an operating system such as Linux"

arsen [322]

Answer:

There are 7 layers in linux.

Explanation:

As networking is difficult and complex.

Imagine if every application had to know how to communicate on every step that would be more than just complex. So, rather than reinvent something which will help it to communicate let’s just make something that will automatically controls the communication and for that protocols came in to live.

As for the linux operating system, it is not exceptional from other operating systems.

There are 7 layers on network protocol stack use to communicate with other network protocol stack.

1. Application layer

2. System call interface

3. Protocol agnostic interface

4. Network protocol

5. Device agnostic interface

6. Device drivers

7. Physical hardware

All the layers vary in their functionality.

One more important thing to remember is that the network protocol stack layers is not one way its 2 way communication. First, when a client request to a network and second, when the request is full filled.

The top most layer is a part of user space, the next five layers comes in the kernel space and the final layer is the physical layer.

Application layer:

When a client or user request to a network the request initially comes to this layer.

On this layer we use tcp/ip protocol.

System call interface(SCI):

When application layer make a call to the kernel this layer handles that call. And take the request to the next layer.

Protocol agnostic interface:

This layer has two functions “talking” or “listening”. There is a thing called sockets which perform these functions and each socket has an id which is used specifically for an application.

Network protocol:

This layer is used for how the data is sent or received.

Device agnostic interface:

It is used to connect data from/to kernel user space and the network device drivers which allows the data to prepare itself for transmission over the medium from the network device.

Physical hardware :

This layer is responsible for the data packets transmission and received from the network medium being used whether cable or wireless.

Write, compile, and test the MovieQuoteInfo class so that it displays your favorite movie quote, the movie it comes from, the ch

Irina18 [472]

Using the knowledge of computational language in JAVA it is possible to write a code that removes your favorite phrase from the movie. It consists of two classes in which one is driver code to test the MovieQuoteInfo class.

<h3>Writing code in JAVA:</h3>

public class MovieQuoteInfo { //definition of MovieQuoteInfo class

//All the instance variables marked as private

private String quote;

private String saidBy;

private String movieName;

private int year;

public MovieQuoteInfo(String quote, String saidBy, String movieName, int year) { //parameterized constructor

super();

this.quote = quote;

this.saidBy = saidBy;

this.movieName = movieName;

this.year = year;

}

//getters and setters

public String getQuote() {

return quote;

}

public void setQuote(String quote) {

this.quote = quote;

}

public String getSaidBy() {

return saidBy;

}

public void setSaidBy(String saidBy) {

this.saidBy = saidBy;

}

public String getMovieName() {

return movieName;

}

public void setMovieName(String movieName) {

this.movieName = movieName;

}

public int getYear() {

return year;

}

public void setYear(int year) {

this.year = year;

}

//overriden toString() to print the formatted data

public String toString() {

String s = quote+",\n";

s+="said by "+this.saidBy+"\n";

s+="in the movie "+this.movieName+"\n";

s+="in "+this.year+".";

return s;

}

}

Driver.java

public class Driver { //driver code to test the MovieQuoteInfo class

public static void main(String[] args) {

MovieQuoteInfo quote1 = new MovieQuoteInfo("Rosebud", "Charles Foster Kane", "Citizen Kane", 1941);//Create an object of MovieQuoteInfo class

System.out.println(quote1); //print its details

}

}
