Network - Application Protocols (Http, Ssh, …)


A page about the transfers/transport protocol of data between two different services.

This is the application level (layer 4) of the OSI.

Not to confound with the transport layer (layer 3) of the OSI model that is only focused on the transport from data from host-to-host (no data format, no security, …)

An application is in this context defined as responsible for displaying received information to the user.

  • a web document for a web client such as a browser.
  • a email

See also I/O - (Input/Output|Read/Write) - Data Access for local data transport.
