    The application layer of an R/3 System is made up of the application servers and the message server. Application programs in an R/3 System are run on application servers. The application servers communicate with the presentation components, the database, and also with each other, using the message server.

    An application sever is a set of executables that collectively interpret the ABAP/4 programs and manage the i/o for then. When an application server is started,these executables all start at the same time.When an application server is stopped,they all shut down together.The number of processes that start up when u bring up the application server is defined in a single configuration fiel is called the application server profile.
    For Example: An application server profile specifies:
    * Number of processes and their types
    * Amount of memory each process may use
    * Length of time a user is inactive before being automatically logged off

    The presentation server is actually a program named sapgui.exe. It is usually installed on a user's workstation.
