At Which Layer Of The Osi Model Would A Physical Address Be Encapsulated?

At Which Layer of The Osi Model Would a Physical Address Be Encapsulated?

The OSI model is a conceptual model called the open system interconnection model (OSI). Its basic function includes standardize and feature the transmission of telecommunication without considering in a specific way of its intrinsic structure and technology. Its major motive is to collaborate or spread the transmission system along with excellent communication protocol. The OSI model is made of different layers. Do you know which layer of the OSI model is best for the encapsulated physical address?  This is the main topic of this article. We discuss here layers of the OSI model.

In the communication system, the transfer of data occurs through the partition in a model. These partitions are seven different layers. From these layers, the physical execution of the transfer part orbits across a transmission average to the highest-level presentation of data in a diffused application. Each middle layer act afunctional class to an above layer or below the layer. The functionality of each layer is described in software by the excellent communication protocol.

In 1970 the OSI model has been developed to assist the crisis of the diverse networking ways to compete for supplication in large national networking in the world. This model is a working product of the open system interlink to the international organization for standardization.

Composition of layer:

There are seven different layers in the open system interconnection model. The architecture of these seven layers is described below. Let’s have a look.  Out of these seven layers, three are the media layer and four are host layers. The three media layers are

Physical:

Its function is to receive or transmit streams over the physical medium.

Datalink:

Well, ground transfer frame data between two nodes interlink by the physical layer.

Network:

Its function is to manufacture a multi-node network. It includes traffic control, routing, and addressing.

The other four are host layers includes

Transport:

Well-ground transmission of datagram between two networking points includes segmentation, multiplexing, and acknowledgment.

Session:

Its function is to manage transmission sessions means the exchange of information through back-and-forth transmissions between two nodes.

Presentation:

Its function is to translate data through a network service it includes  compression data encryption, and decryption, coding

Application:

Its function is to file access and sharing resources. It is high-level security and APIs.

Out of these seven layers, the layer used in the OSI model the physical layer is encapsulated in the network layer the reason for this response is that the IP addresses are encapsulated in the network layer. In the data link layer, physical addresses are encapsulated. in the transport layer, the port address is encapsulated. But in the physical layer, no address is encapsulated.

Network layer:

In the network layer packets are transferred from one node to another node in a connected system called a different network. The network is a medium size in which all nodes are connected and every node has a different function and every node has an address. This address allows nodes to transfer information to other connected nodes. If the information is large that is transferred on the data link layer between two nodes. It is possible the information is transmitted in several fragments at one node, sending these fragments individually and these fragments are reassembled at another node.

The information delivered with the network layer is may or may be reliable. The network layer in which the physical address is encapsulated.
