Database Layer where the RDBMS database is for example SQL Server or Oracle.
Application Layer is the layer where the SAP executables are installed. This layer connects to the database layer to do all the processing and contains a SAP instance.
Presentation Layer is the GUI that you use to connect to the SAP System via the application layer. This could be through the SAP GUI (SAP FrontEnd), a Web GUI or even a Java GUI (on a mobile phone).
Communication between the layers is via TCP/IP
Two tier architecture would have the database and application layers on one machine and the presentation on another however the three tier architecture is the most common. I will however build a two tier system due to lack to hardware.
