Active Directory Logical Architecture
Active Directory's logical layer determines how you see the information contained in the data store and also controls access to that information.

This provides a consistent way to access directory-stored information regardless of type. For example, you can obtain information about a printer resource stored in the directory in much the same way that you can obtain information about a user resource.
To better understand Active Directory's logical architecture, you need to understand the following topics:
Active Directory objects
Active Directory domains, trees, and forests
