SharePoint 2010 Tutorial Free - SharePoint 2010 Architecture

     It has 4 layers

    1) SharePoint Sever 2010(Enterprise/Standard)
    2) SharePoint Foundation 2010
    3) SQL Server 2008,IIS 7.0 and .Net 3.5 Framework
    4) Windows server  2008(64bit)

Considering that you have just started learning SharePoint,trust me even if you know this you have started very well.Cheers !

So normally when I go for interviews in companies ,I just draw 4 storey building and name each block as mentioned when asked to define the architecture of SharePoint 2010

And as you learn SharePoint,eventually you will come to know what each layer contains.
