What is WSS ?

Windows SharePoint Services (WSS) is the basic part of Microsoft SharePoint, offering collaboration and document management functionality by means of web portals, by providing a centralized repository for shared documents, as well as browser-based management and administration of them. It allows creation of Document libraries, which are collections of files that can be shared for collaborative editing. SharePoint provides access control and revision control for documents in a library.

It also includes a collection of web parts, which are web widgets that can be embedded into web pages to provide a certain functionality. SharePoint includes web parts such as workspaces and dashboards, navigation tools, lists, alerts (including e-mail alerts), shared calendar, contact lists and discussion boards. It can be configured to return separate content for Intranet, Extranet and Internet locations. It uses a similar permissions model to Microsoft Windows, via groups of users. Active Directory groups can be added to SharePoint groups to easily tie in permissions. Alternatively, other authentication providers can be added through HTML Forms authentication
