One of the fundamental kinds of Web sites that SharePoint 2010 allows you to create is a team site. A team site is a SharePoint site that you can use to collaborate with your coworkers. If the team site is hosted in your company’s extranet or by a public hosting company, you may even be able to collaborate with people outside your organization. In most cases, an administrator will create a team site for you. Many kinds of teams can use a SharePoint team site to collaborate.
 For example:
✓ Department members can use document libraries to upload document files and enter meetings in a team calendar.
✓ Project members can use a team site home page to post announcements and track important dates.
✓ Corporate communications can use a team site to store the documents and track the tasks required for preparing the company’s annual report.
