Transcript of OSI Model
Antonio Camacho Molina
What is the OSI model?
Is a model that standardizes communication between network end points.
It was crated because some years ago communication between different networks depend on its brand for example a IBM network was not able to exchange data with an Apple network.
It was created by the ISO to avoid the problem in 1984.
The OSI model standardizes communication in 7 levels.
Open System Interconnection
Layer 1 or Physical Layer
This layer is in charge of generating the codes in 1 and 0 this is called binary code and this layer is located in the cables and in the optical fiber.
Layer 2 or Data Link Layer
This layer as its name says is the physical link that sends the data to other place and provides access to the network.
Layer 3 or Network Layer
The network layer deals with organizing the data for transfer and reassembly it. This layer also handles aspects of Routing Protocols.
Layer 4 or Transport Layer
Detect errors and lost data.
Recover lost data.
Manage retransmission of data.
Layer 5 or Session Layer
This layer organizes the user applications and track your connections to other servers.
Layer 6 or Presentation Layer
This layer is important because it this layer is important because it guarantees that the data can be understood in any system and translates the data if it's necessary.
Layer 7 or Application Layer
The OSI application layer is responsible for displaying data and images to the user in a human-recognizable format. In other words this layer is the user interface
