What Does Layer 7 Mean?
Layer 7 refers to the seventh and topmost layer of the Open Systems Interconnect (OSI) Model known as the application layer. This is the highest layer which supports end-user processes and applications. Layer 7 identifies the communicating parties and the quality of service between them, considers privacy and user authentication, as well as identifies any constraints on the data syntax. This layer is wholly application-specific.
Techopedia Explains Layer 7
In the OSI model’s application layer, as opposed to the Internet model, is narrow in scope and defines it as interacting directly with the application which is responsible for displaying images and data to the user as a human-recognizable format in order to allow the user to interface with the layer below it, which is the presentation layer. This layer interacts with software applications which implement a communication component.
