the server hosting the replica of Active Directory database is called Domain Controller. In it's database is all information about all objects, that exist in particular Active Directory domain.
If your questions is"The directory containing information about objects in a domain resides on computers called ___ controllers?"Then the answer is Domain Controllers.Reference, Pg. 444 Network+ Guide to Networks, Fifth Edition, Tamara Dean.

Active Directory stores information about all the objects, resources on the network, policies applied on them and permissions on the resources..objects can be users, computers, printers etc
LDAP
The DS tools consist of the following commands DSQUERY - search for active directory objects matching criteria DSGET - retrieves selected attributes from active directory objects DSMOD - modify attributes for one or more active directory objects DSADD - create active directory objects DSMOVE - move active directory objects DSRM - removes/deletes active directory objects
In LDAP-compatible directories, a schema is the set of definitions of the kinds of objects and object-related information that the directory can contain.
LDIFDE is a robust utility. This utility enabled you to import/export information from/to Active Directory. LDIFDE queries any available domain controller to retrieve/update AD information. Ldifde creates, modifies, and deletes directory objects on computers running Windows Server 2003 operating systems or Windows XP Professional. You can also use Ldifde to extend the schema, export Active Directory user and group information to other applications or services, and populate Active Directory with data from other directory services
DSADD can add user,computers and groups all
A Domain is a logical group of computers having versions of Microsoft Windows OS.All these computers shares a central database which is known as Active Directory.An Active Directory is basically group of computers, users, objects, etc.
The Active Directory schema defines the kinds of objects, the types of information about those objects, and the default security configuration for those objects that can be stored in Active Directory. The Active Directory schema contains the formal definitions of all objects, such as users, computers, and printers that are stored in Active Directory. On domain controllers running either Windows 2000 or Windows Server 2003, there is only one schema for an entire forest. This way, all objects that are created in Active Directory conform to the same rules. The schema has two types of definitions: object classes and attributes. Object classes such as user, computer, and printer describe the possible directory objects that you can create. Each object class is a collection of attributes. Attributes are defined separately from object classes. Each attribute is defined only once and can be used in multiple object classes. For example, the Description attribute is used in many object classes, but is defined only once in the schema to ensure consistency.
Active Dirctory stores information about all the objects, resources on the network, policies applied on them and permissons on the resources
