Application Layer: OSI Model

  • The Application Layer is the topmost layer of the OSI Model and has the responsibility for providing interface among users and the software application.
  • It is the front-end layer where users actually communicate and the other six-layer only play their respective roles in the back-end.
  • Application Layer does not directly act as an application but, it is an intermediate between an actual software application and the users.
  • File transfer, emails, remote access, etc. are some of the examples of applications where users interact.

Application Layer : Functions & Features

  • Some of the major functions & features of this layer are:
    • Proper UI/UX of software application on different devices.
    • Synchronization.
    • Communication establishment.
    • Identifying communication users/partners.
