Layer 7 refers to the top layer in the 7-layer OSI model of the Internet. It is also known as the "application layer." It's the top layer of the data processing that occurs just below the surface or behind the scenes of the software applications that users interact with. The main similarity is in their construction, as both use layers, although the OSI model consists of seven layers, while TCP/IP consists of just four layers. Another similarity is that the upper layer for each model is the application layer, which performs the same tasks in each model but may vary according to the information each receives.
