Open System Interconnection Reference Model (OSI Reference Model or OSI Model)

The OSI model is the model that is used to when data is sent over any network. The process starts the top of the model (layer 7) and works its way down until it is sent on its way through the network.

When the package has reached its destination its starts at the bottom of the model (layer 1) and makes its way back up again
