OSI Basic Reference Model

OSI Basic Reference Model - Architecture model that describes how communication can be executed between systems of different vendors. Basically this model is the logical structure of network operations that have been standardized by the ISO (which consists of seven layers). This model allows a computer or device that meets the requirements of OSI to be able to interact with other equipment that meets the requirements of OSI.
to -7 layer starts from the bottom of the physical, data link, network, transport, session, presentation, and application

OSI Seven Layers in the Networking World

Seven OSI Layer - In the world there is a term with osi network layer, layer osi seven parts. There was the seventh osi layer, is

1. Physical is the lowest layer in the OSI model. Serves to define the network transmission media, signaling method, synchronization bits, network architecture (such as Ethernet or Token Ring), network topology and wiring.

Definition of OSI Layers

OSI LAYER - Understanding the OSI model (Open Systems Interconnection) is a conceptual model consisting of seven layers, each layer has a different function.
OSI Layer counting starts from the top was the highest to the bottom,

7. Application is the highest layer of the OSI model, the layer below it works for this layer, application layer is the task of Functioning as an interface with applications with network functionality, govern how applications can access the network, and then make the error messages.
