Microsoft SharePoint Services: Windows SharePoint Services acts as the foundation for collaboration across client and server environments and is a component of the Windows Server. It is used to create Web sites for sharing and document collaboration and provides a platform for application development focused on well-established sharing and communication services like portals and Web-based conferencing. Microsoft has been developing additional applications by using the Window SharePoint Services platform as a base. For example, Microsoft now offers a collaborative portal application called the Microsoft Office SharePoint Server, which is based on Windows SharePoint Services.
