In case you are wondering how networks exchange data or connect with each other, the OSI model comes into play here. Today I will show you what the OSI model protocol is for. Based on the characteristics assigned to it by a manufacturer or a developer, we can know that the network protocols are different.
I'll show you how standards established by ISO, ensure better operation and greater compatibility among the great variety of network technologies. I invite you to continue reading on the OSI model protocol, in order to learn how information travels from an application to other computers over 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 like finding your Android build number or finding your Windows Server product key easily.
At the 7 levels that are responsible for the operation of the OSI protocol several specific functions are assigned, in so that it can do its job correctly. Therefore, when you send information to others via a computer, the layers of the OSI model work in such a way that it does information come received completely.
The layers of the OSI Model protocol and their characteristics
The layers in the OSI model protocol they are responsible for the operation and management of the physical part of the connection in the network, such as routing, communication, among others.
Physical
The first layer we find is the physical layer. It is responsible for working only with elements that are physical in the connection part. It works focused on the electronic part in so that 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 the transmission and access to support. Here the bits are constructed with all the information, along with the other elements, so that the information transmission work is done 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 coverage.
Network
In level number 3 we find the network that can identify the routing between two, three or more connected networks. In this level you work so that the data can arrive from the transmitter to the receiver, carrying out the routing and switching necessary for the message to arrive. This level has the task of knowing the type of network topology in which it operates so that it can carry out the work to send information.
Freight
In the fourth layer we find the layer of transportation. As the name suggests, it is in charge of carrying the data within the transmission from its inception to its destination.
In this level, sufficient quality is given so that the information sent by the user can reach its destination correctly.
The session
In the fifth level is the session level. It is responsible for maintaining open contact between two devices during the transmission of information. This way you can send information from one place to another and the session level will remain open till a when the information is not transmitted in its entirety.
The presentation
The sixth level is the presentation level. This level can be described as the translator, since he has the ability to translate the information of bit in our language. Remember that when you submit information, it comes converted into codes to be sent in bit format, when they arrive at their destination, the presentation takes care of translating the codes into an understandable language.
The application
In the last level is the application level. It allows people to take action. For example, the option to submit a webpage from Mac, just to name one.
