TCP IP Architecture Model
Unlike the ISO / OSI reference model, TCP IP architectures are only divided into 4 layers. The exchange of information between layers is also precisely defined, with each service utilizing low-level services and providing its services at a higher level.
In this article, we will see some important TCP, IP Architecture Model, Network layer, Transportation layer, the Application layer.
Network interaction layer (Data link)
Very low TCP / IP model layer. Its function is to provide access to the transmission medium and varies depending on the implementation of the medium.
Network layer
The network layer provides network addresses, routes, and data transfer. The protocols used will be of ongoing interest in DHCP by IP and ARP.
IP Protocol
It is the basic protocol of the network layer and usually the whole internet. It sends datagrams, which are independent units that contain information about the location, source, and a serial number of data.
The sequence number is used to recreate the message, as the order of delivery of the data may not be the same as the order of the message and the reliability of the delivery is not guaranteed at all.
IP protocol versions:
“IP v4 – 32-bit address. Provides approximately 4 billion different addresses which are not yet available.
“IP v6 – 128-bit address. Switching to v6 will bring (bring) higher security, QoS, package splitting, and many other IP addresses. (Transition from IP v4 to IP v6 should be supported by the system provider)
ARP Protocol
The ARP summary represents the Address Resolution Protocol. This legal process is used to locate a local address (MAC) based on a known IP address. If required ARP sends information regarding the required address to all channels in the network – Broadcast.
ext, the channels respond with a message containing their MAC. If the desired device/channel is out of place/part, the appropriate router will respond in its place.
Transportation layer
The transport layer is only used on storage devices and adjusts network behavior according to device/application requirements.
Application layer
The app background is made up of applications that utilize complete resources to meet the needs of users. Examples of specific protocols for example are FTP, DNS, and DHCP.
System agreements use TCP, UDP, or both resources at the same time.
The so-called holes are therefore used to distinguish between application contracts, representing the type of application label. It is possible to change the holes in the service settings, but each service has a default port that is not changed for most services and is used as an unregistered standard.
“FTP = 21
“DNS = 53
“DHCP = 67 + 68

TCP IP Architecture Model FAQ
Why does the TCP/IP model use layers?
Each section manages a different part of the communication. It can be called Transmission Control Protocol/Internet Protocol – TCP/IP – model. Connectivity allows standards to be deployed and adapted as new hardware and software are developed.
How does the TCP/IP architecture work?
Here’s how it works. TCP/IP is a two-layer program: the upper layer (TCP) divides the content of the message into small “data packets” that are then sent over the Internet to be reassembled into the original form of the message by the TCP host computer.
What is the TCP IP architecture model?
TCP/IP is a layered server architecture system where each layer is defined according to a specific function to be performed. All four layers of TCP/IP work together to transfer data from one layer to another. Application layer. The transport layer is the Internet layer.
How many layers are there in TCP IP architecture?
4 The TCP/IP Protocol Stack consists of four main layers: Application, Transport, Network and Link layers.
What is the lowest layer of the TCP IP model?
The connection layer is the lowest layer of the TCP/IP model; also referred to as the network interface layer in some texts. The link layer combines the functions of the physical and data link layers in one layer.
