-1 - Physical -> Bits+==== Explanation ====
  
 Since layer 7, 6 and 5 are represent actual data including following basic elements which are component, collaboration,​ interface, function, interaction,​ process, event, service and objects. In short it defines how application should talk to another application,​ defines encryption and decryption of data from application layer, including the data types. Lastly layer 5 controls the connection between computer, in general starting-stopping and managing the connection between applications. If anybody has worked with apache httpd, keep alive variable in configuration closely control this behavior. Since layer 7, 6 and 5 are represent actual data including following basic elements which are component, collaboration,​ interface, function, interaction,​ process, event, service and objects.
