Which Of The Following Represents The Tcp/Ip Four-Layer Reference Model?

Which of the following represents the TCP/IP four-layer reference model?
The TCP/IP model is a set of communication protocols. These are developed in 1974 by the department of defense. We all know that every network protocol consists of a set of rules. It governs how the data is exchanged between the network.

But when we talk about the network protocol, the TCP/IP model will act as a rulebook. These TCP/IP has an end-to-end data knowledge. It tells how the data should be packetized and get addressed. It also tells how it gets transmitted and received.
Without the presence of the TCP/IP protocol, most of the computers didn’t even know where to start the process. Let us know how we can understand the TCP/IP rulebook. The TCP/IP protocol has separated the protocol into four distinct layers. This can also be called the four-layer model.

Let us know the four different layers in detail. They are the application layer, transport layer(also called the TCP layer), Internet layer(IP layer) and the last one is a network interface. Let us learn in detail about these four layers.

The first type of layer is the application layer. The application layer can easily get understand. The application layer is nothing but, which is visible to the user. For suppose the video that we are watching, or a website that we are seeing on the internet is the example of the application layer. In simple words, the application layer contains all types of programs, web browsers, and web servers that are used to exchange information. It sends the files and information to the transport layer and receives them from the transport layer.

Here, after receiving the message from the application layer, the transport layer(TCP layer) doesn’t care about the information that the application layer has sent. The transport layer(TCP layer) is only interested in how the information sent is going to get its desired location.
This information is packetized by the transport layer of the TCP/IP protocol. Here the TCP/IP protocol cannot send the information that is in fully assembled form, because it is too complex. Here the TCP/IP protocol plays the main role by breaking down the complex information into smaller parts. These parts we call the packets. These packets are only 1-kilo bytes in size. After dividing this into smaller packets, these packets are sent into the next layer called the IP layer/Internet layer.

The Internet/IP layer will only deal with things called IP addresses. We can simply say that the IP address is similar to the address of our home. It defines the exact location or a specific network that can be found with the help of the IP addresses.
The internet or IP layer send the packet through the proper interface by addressing each tiny packet to the proper destination.
The network interface is like the central hub where all the information is passed through it. It is where all the information is moved to the different IP addresses. This four-layer model is always used on the internet. It allows to send, print, and receive images or information from other users.
