SharePoint sites are organized into folders, just like any other web site, but there are some terms SharePoint uses that should be explained up front:
- Virtual server
The root location for one or more web sites. SharePoint can host multiple virtual servers on a single server. Each virtual server can have its own domain name. For example, www.usingsharepoint.com and http://www.mstrainingkits.com are hosted on the same SharePoint server.

A group of top-level sites on one virtual server. Site collections allow separate administration of related sites.
- Top-level site

- Subsite
