TCPIP Model What are Layers and Characteristics

What does TCP/IP stand for? 

The TCP/IP Model helps you figure out how to connect a certain computer to the internet and how to send data from one computer to another. When multiple computer networks are linked, it helps make a virtual network. The TCP/IP model aims to make it possible to talk across long distances. 

Transmission Control Protocol and Internet Protocol are what TCP/IP stands for. TCP/IP Stack was made as a model to offer a highly reliable byte stream from one end of the internet to the other. Get the knowledge of different types of layers in the TCP IP model by joining CCNA Course in Chennai.

What Makes Up TCP? 

Here are the most important things about TCP/IP protocol: 

Support for a TCP/IP architecture that can be changed. It’s easy to add more systems to a network. In the TCP/IP protocols suite, the network stays together until both the machine at the source and the machine at the destination work properly.

TCP is a protocol for making connections. TCP is reliable and ensures that data that comes in out of order is put back in order. TCP lets you control the flow of data so that the sender never sends too much information to the receiver. The TCP/IP model has four layers. In this TCP/IP tutorial, we’ll talk about the different layers and what each one does: 

Layer of Applications 

The top level of the OSI model is the application program, which talks to the application layer. The OSI layer that is most important to the end-user is the application layer. This means that the OSI application layer lets users talk to other software programs. 

The application layer works with software applications to create a component that can talk to each other. The OSI model never covers how an application program figures out what data means. 

Layer of Transport 

The transport layer constructs on the network layer to move data from a process on a source system to a process on a destination system. 

It can be hosted on one or more networks, and the quality of service functions is also kept up to date. 

It figures out how much data should be sent, and where and how fast it should be sent. This layer takes the message from the application layer and adds to it. It helps make sure that data units are sent without mistakes and in the right order. 

The transport layer lets you control the reliability of a link by controlling flow, handling errors, and segmenting or de-segmenting data. The transport layer also confirms that the data was sent successfully and sends the next data if there were no errors. The most famous example of a transport layer is TCP.

Internet Layer 

The next layer of the TCP/IP model is the Internet layer. A network layer is another name for it. This layer’s main job is to ensure that packets sent from any network or computer get to their destination, no matter how they get there. 

With the help of different networks, data sequences of varying lengths can be sent from one node to another using the Internet layer. This is both a functional and procedural method. Message delivery at the network layer doesn’t mean that the network layer protocol is reliable. 

The Network Interface Layer (NIL) 

This layer of the last TCP/IP model is the Network Interface Layer. A network access layer is another name for this layer. It lets you specify how data should be sent over the network. It also tells how bits should be signaled optically by hardware devices that connect directly to a network medium, such as coaxial, optical, coaxial, fiber, or twisted-pair cables. A network layer is made up of the data line as it is described in the OSI reference model article. This layer tells the network how the data should be sent through it. This layer is in charge of getting data from one device to another on the same network.
