application layer: It allows applications access to network services, such as file and printer sharing, as well as file transfer and management services. This would be the layer that a programmer uses to allow his application to access a network service, such as linking into a database.

Although this explains the flow of data and what processes are performed by each layer starting with the physical layer and working to the top, or application, layer, the process would be the same, only reversed, for data flowing from the application layer and down to the bottom, or the physical layer.
