TCP / IP Protocol: The 4 Layer Model
[Solved] Which of the following is NOT the layer of TCP 
Which of the following is NOT the layer of TCP/IP protocol?. The application layer interacts with an application program, which is the highest level of the OSI model
It means the OSI application layer allows users to interact with other software applications.. An internet layer is a second layer of TCP/IP layers of the TCP/IP model
The transport layer builds on the network layer in order to provide data transport from a process on a source system machine to a process on a destination system. It is hosted using single or multiple networks, and also maintains the quality of service functions.
Which one is NOT one of the 4 layers of the TCP 
Which one is NOT one of the 4 layers of the TCP/IP model. Application layer is the top most layer of four layer TCP/IP model
Application layer defines TCP/IP application protocols and how host programs interface with Transport layer services to use the network.. Application layer includes all the higher-level protocols like DNS (Domain Naming System), HTTP (Hypertext Transfer Protocol), Telnet, SSH, FTP (File Transfer Protocol), TFTP (Trivial File Transfer Protocol), SNMP (Simple Network Management Protocol), SMTP (Simple Mail Transfer Protocol) , DHCP (Dynamic Host Configuration Protocol), X Windows, RDP (Remote Desktop Protocol) etc.
The position of the Transport layer is between Application layer and Internet layer. The purpose of Transport layer is to permit devices on the source and destination hosts to carry on a conversation
What are the four layers that make up TCP 
Chances are that in your day-to-day life, you use the Internet to do all kinds of tasks or enjoy your leisure time, but it isn’t likely that you’ve ever stopped to think about how it works.. Yes, basically, all we need is a computer and an internet network to connect to and that’s it.
In a simple Google search or when we want to watch a movie on Netflix, our devices develop communication with the internet network that is quite complex.. This is when the TCP/IP protocol comes into use and when it becomes important that its four layers work well.
To get into the subject, you need to know what TCP/IP is so that you have a basic definition of the subject and so that you can understand each of its layers.. Its acronym comes from the full name of Transmission Control Protocol/Internet Protocol.
TCP/IP MODEL 
Today’s most popular protocol in use is the Transmission Control Protocol/Internet Protocol (TCP/IP). Currently, the Internet and most enterprise intranets use TCP/IP because of its popularity, flexibility, compatibility, and ability to deploy on large and small networks
The TCP/IP model consists of four layers instead of the seven of the OSI model. The four layers of the TCP/IP model correlate to the seven layers of the OSI model, but layers of the TCP/IP model combine several layers of the OSI model.
In other words, the Internet layer and the network layer describe the same thing, just as the transport layers, the other two layers of the TCP/IP model are composed of multiple layers of the OSI model.. TCP/IP is open-source; its standards and protocols are defined in a public forum through the IETF (Internet Engineering Task Force (IETF)) and published by RFC (Requests for Comments).

Both models have different layers, functions, and standards. In this article, you will learn about the benefits and drawbacks of using TCP/IP model over OSI model.
Enhance Network Connectivity with Network Insight 
To understand network connectivity, we will break networking down into layers. Then we can fit the different networking and security components that make up a network into each layer
Networking does not just magically happen; we need to follow protocols and rules so that two endpoints can communicate and share information. These rules and protocols don’t just exist on the endpoint, such as your laptop; they also need to exist on the network and security components in the path between the two endpoints.
These networking models are like a blueprint for building a house. They allow you to follow specific patterns and have certain types of people, which are protocols in networking.
IP and How Does it Work? 
TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP is also used as a communications protocol in a private computer network (an intranet or extranet).
TCP and IP are the two main protocols, though others are included in the suite. The TCP/IP protocol suite functions as an abstraction layer between internet applications and the routing and switching fabric.
TCP/IP requires little central management and is designed to make networks reliable with the ability to recover automatically from the failure of any device on the network.. The two main protocols in the IP suite serve specific functions
TCPIP Protocol Suite 
A protocol is a set of rules and conventions that govern how devices on a network exchange information. This section discusses one of the more commonly used protocol suites: TCP/IP
Nevertheless, TCP/IP needs to be covered to some degree so that you can better understand the overall operation of network protocols; these discussions are expanded in later chapters concerning OSPF.. The TCP/IP protocol suite is also referred to as the TCP/IP stack, and it is one of the most widely implemented internetworking standards in use today
TCP and IP are the two core protocols that exist within the TCP/IP protocol suite, and their place in the TCP/IP protocol stack is clarified in the following paragraphs.. Although at the time, the Internet was a private network and TCP/IP was designed specifically for use within that network, TCP/IP has since grown in popularity and is one of the most open protocols available for use in networks today

People have always communicated with each other – initially by face-to-face communication through gestures and sounds, then over a distance through written messages and signals in the form of fires, lights or flags. Technology, for instance in the form of electrical signals, has reduced many of the limitations of distance
In this unit we regard a communication network as the means of interconnecting devices so that two-way communication is possible, and we shall focus on networks that interconnect telephones or computers. However, you should bear in mind other forms of network such as television and radio networks, which are primarily one-way, broadcast networks
This OpenLearn course provides a sample of postgraduate study in Computing & IT. evaluate technical descriptions of communication protocols and demonstrate an understanding of their operation
Layers, Structure & Functions 
The TCP/IP model is a part of the Internet Protocol Suite. This model acts as a communication protocol for computer networks and connects hosts on the Internet
This concept of TCP/IP is not just important for people in the computer or IT fields but also is an essential part of the Computer Knowledge syllabus, included in major competitive exams.. Before, diving deep into the different aspects of the structure, refer to the table below and know about some basic and introductory features of the model:

To discuss computer networking, it is necessary to use terms that have special meaning. Even other computer professionals may not be familiar with all the terms in the networking alphabet soup
Although descriptions and examples should make the meaning of the networking jargon more apparent, sometimes terms are ambiguous. A common frame of reference is necessary for understanding data communications terminology.
This architectural model, which is called the Open Systems Interconnect (OSI) Reference odel, provides a common reference for discussing communications. The terms defined by this model are well understood and widely used in the data communications community — so widely used, in fact, that it is difficult to discuss data communications without using OSI’s terminology.
What is TCP/IP? 
When two computers communicate over a network, they need a means of routing traffic from the source computer to the destination. Every computer on the Internet and on private internal networks is identified by an IP address.
The IP header in a network packet contains the information needed to get a packet from point A to point B. In addition to the IP address, an IP header contains values designed to reorganize out-of-order packets and perform other critical tasks.
IPv4 addresses have the format X.X.X.X, where each X is a value in the range 0-255. Due to concerns about depleting the pool of available IPv4 addresses, the IPv6 protocol was created
Let us have a look at the topics covered in this article:. Before going any further, look at this video in which our Cyber Security specialists explain the nitty-gritty of network security in detail:
The architecture  of TCP has evolved from studies in methods for connecting multiple packet-switched networks. The central aim of the TCP/IP model is to enable the sending of data packets to one application on a single computer
The TCP/IP model sets out how packets exchange information through the web. This set of communication protocols determines how data is to be broken, addressed, transferred, routed, and received for sharing
