The three networking models that provide a framework for network communication are :
A networking model represents a common structure or protocol to accomplish communication between systems.
These models consist of layers. You can think of a layer as a step that must be completed before you can go on to the n,ext step and, ultimately, to communicate between systems.
A protocol is a formal description of messages to be exchanged and rules to be followed for two or more systems to exchange information.
- Model = Structure
- Layer = Function
- Protocol = Rules
