OSI Reference  Model

The cost  reference  model was developed by  the ISO for  international  standardization of  protocols  used at various layers. The model  uses well defined descriptive layers  that specify what happens  at each stages of data processing  during  transmission. It does not specify  the exact  services  and protocols that will be sued in each layer.

The  OSI model  has seven  layers. Each  of the layers is described next.

One  of the main  objective of OSI RM is to define develop protocols to perform the  functions  of each layer and implementation detail of the services it is providing.
