ago about 3 weeks there was a symposium Information Technology, and I remember a conference I attended, who spoke of the OSI model, I had no idea that was, I imagined something like rules about something, but I realized that research was not entirely lost. OSI Model This is a descriptive network model which was developed by OSI .
Briefly is a framework for defining interconnection architectures devices. Surge
Briefly is a framework for defining interconnection architectures devices. Surge
This arises because having many technologies, manufacturers and who developed or ivan develop communication devices , a standard which everyone could understand in some way no matter what their technologies do not match. It is similar as the rules used for the manufacture of clothing, hygiene and ecology, among others.
Layers:
layers are handled by this model, 7 in these layers, you specify the protocol to be used in each layer. These include:
Physical Layer 1: in this layer handles the physical connections from the computer to the network.
Layer 2 traffic link: In this layer, making the physical address (assigned the network type and sequence of packets used)
Layer 3 network layer In this, determine how that data will be sent to the team that will
Layer 4 Transportation: In this, the monitor, if the data comes from more than one application and integrates each application data into a single network flow
Layer 5 Session: in this layer is to establish maintain backward and log in communication devices
Layer 6 presentation: In this, what is done is to collect information to make it available to other application and these can be implemented.
Layer 7 application: The latter is that it interacts with the OS or application when you decide to do an action, either send data, read, among others. Interaction
including:
This can give and needs to be a interaction, since this is an exchange of data or information , but this works on each layer add control information data and each layer analyzes the destination and removes the control information.
