Window SharePoint Service (WSS) 3.0 and Microsoft Office SharePoint Server (MOSS) 2007 both provide a platform for communication, collaborative development, content management, search capability etc. But how do they differ from each other, what benefits do each of them provide over other, in which scenario to use WSS and in which to use MOSS?
Gone are days when file based sharing approach was a way of collaborative development. Even though this approach had been in use for long time but it had several of its inherent problems and limitations. Microsoft offers solutions for all these problems/limitations and even much more with "SharePoint Products and Technologies" which has two products viz. Windows SharePoint Service 3.0 and SharePoint Server 2007 in its arsenal. Both of these products provide a power platform for communication, collaborative development, content management, powerful and enhanced search and helps people in staying connected across divisional, organizational and geographic boundaries. Both of these products are based on .NET framework for development and SQL Server as back-end to store content and configuration data.

Microsoft Office SharePoint Server (MOSS) 2007
Microsoft Office SharePoint Server (MOSS) 2007 is an application which runs on the WSS 3.0 platform and extend the collaborative development foundation of WSS 3.0 to a new level i.e. MOSS 2007 is superset of WSS 3.0.
