Application layer protocols

A few examples of application layer protocols are the Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), Post Office Protocol (POP), Simple Mail Transfer Protocol (SMTP), and Domain Name System (DNS). The presentation layer prepares data for the application layer.

What are Layer 7 applications?

Layer 7 or the application layer of the OSI reference model deals directly with applications. Within this narrow scope, layer 7 is responsible for displaying data and images to the user in a format humans can recognize. This in turn enables users to interface with the presentation layer below the application level.
