Hi Ashok
R3 stands for the 3 tier architecture.
There are 3 servers in R3:-
1) Presentation Server - SAP GUI.
2) Application Server - ABAP.
3) Database Server.
The R/3 System is an open system. It supports a variety of network communication protocols.
Information can be exchanged between R/3 Systems and other R/3, R2, or non-SAP systems across a
network.
SAP supports the Transmission Control Protocol / Internet Protocol (TCP/IP) and System Network
Architecture: Logical Unit 6.2 (SNA LU6.2) protocols. Communication within the R/3 System uses
the standard protocol TCP/IP. LU6.2 was developed by IBM and is used to communicate with
mainframe-based R/2 Systems.
R/3 application programming supports the following communication interfaces: common
programming interface communication (CPI-C), remote function call (RFC), and object linking and
embedding (OLE) automation.
Pls reward pts if help.

Hi friend,
R/3 stands for Real time and
3 stands for 3 tier architecture.
before R/3 we have client sever architecture.
in this client has to wait for server reply.
which in the sense slow process due to network problems and server config.
so the advanced technique for client server is R/3 arch.
in this we have
1..presentations server : where we can able to write coding and design screen and menus
simply it is front end.
2..application server : once you develop a code it has to be execute.This execution will
comes under application server.your abap code will execute in application server only.
3..database server : once you create a program or some table or some thing,we want to store that
object permanently. so here we want one database.that is called data base server.
reward if useful.
regards.
