Application layer

Layer 7 in the OSI reference model. The Application layer provides interfaces to permit applications to request and receive network services.

Application Layer— an end-to-end protocol, in the sense that a direct link is established between the sending device and the receiving device. Facilitates the use of network application programs, such as E-mail. By adhering to a set of protocols (embedded in the software), users can communicate with one another, regardless of the terminal or the hardware platform on which the application resides.
