What is the OSI model protocol for, how does it work, characteristics and its layers?

In case you are wondering how networks exchange data or connect with each other, the OSI model comes in here. Today I will show you what the OSI model protocol is for. According to the characteristics assigned to it by a manufacturer or a developer, we can know that the network protocols are different.

I will show you how the standards established by ISO, grant a better operation and more compatibility between the great variety of network technology. I invite you to continue reading about the OSI model protocol, so that you learn how information travels from an application to other computers through the network.

How does the OSI model protocol work?

The OSI model protocol works directly with its 7 layers, into which the laborious digital information and its communication process are divided. It’s something like locating the Android build number or finding the Windows Server product key easily.

The 7 layers that are responsible for the operation of the OSI protocol are assigned different specific functions, so that it can carry out its work properly. Therefore, when you send information through one computer to others, the layers of the OSI model work so that this information is received completely.

The layers of the OSI Model protocol and their characteristics

The layers in the OSI model protocol are responsible for working and managing the physical part of the connection in the network, such as routing, communication, among others.


what is the OSI protocol


The first layer that we find is the physical layer. It is responsible for working only with the elements that are physical in the connection part. It works focused on the electronic part so that the information in the form of bits is directed from one place to another.

The data link of the OSI Model protocol

In layer 2 we find the data link, which is responsible for addressing the physical data, detecting errors in transmission and access to the medium. Here the bits are built with all the information, along with the other elements so that the work of transmitting the information is executed correctly.

The element that works with this layer is the router or also known as a switch, it works to send and receive information. Hence the importance of choosing a good router, for example, choosing the best dual band router for greater Internet reach.


In layer number 3 we find the network that can identify the routing between two, three or more networks that are connected. In this layer we work so that the data can get from the transmitter to the one who receives it, carrying out the routing and the necessary switching so that the message can arrive. This layer is in charge of knowing the type of topology of the network in which it works so that it can carry out the work of sending the information.


In the fourth layer we find the transport layer . As its name implies, it is in charge of transporting the data within the transmission from its inception to its destination.


how the OSI model works

In this layer, sufficient quality is given so that the information sent by the user can reach its destination in the correct way.

The session

In the fifth layer is the session layer. It is responsible for maintaining open contact between two devices while information is being transmitted. In this way, you can send information from one place to another and the session layer will remain open until the information is transmitted in its entirety.

The presentation

The sixth layer is the presentation layer. This layer can be described as the translator, since it has the ability to translate the information of the bits in our language. Remember that when you are sending information, it is converted into codes to be sent in bit form, when it reaches its destination the presentation is responsible for translating the codes into an understandable language.

The application

In the last layer is the application layer. It allows people to take actions. For example, the option to mail a web page from Mac , just to name one.
