WSS Versus MOSS
Many people are unclear about the difference between Windows SharePoint Services (WSS) and Microsoft Office SharePoint Server 2007 (MOSS).
Windows SharePoint Services (WSS) are free with Windows Server. In contrast, MOSS is not free and it is installed on top of WSS. MOSS has both a server cost and a client access license (CAL) cost. To upgrade the standard CAL to the Enterprise CAL is an additional cost.
MOSS provides the following additional features beyond what is included with WSS.
1. The My Site personal site
2. Site Directory (automatically creates a site map and presents it in an easy-to-use format)
3. User Profiles and Profile Store
4. Audience Targeting
5. Pre-built workflow templates (Approval, Collect Feedback, Collect Signatures, Disposition Approval, Translation Management, Issue Tracking). WSS does not provide workflow templates like MOSS. Custom workflows can be built using Visual Studio or SharePoint Designer.
