2.3.7. Application Layer

The application layer, layer 7, controls how the OS and its programs collaborate with the network. The applications you utilize, for example, Microsoft Word or Lotus 1-2-3, are not a part of the application layer, but rather they unquestionably profit by the work that goes ahead there. A case of programming at the application layer is the network client software you utilize, for example, the Windows Client for Microsoft Networks, or the Windows Client for Novell Networks. It likewise controls how the OS and applications associate with those clients.
