schema ( cheater, go look in the book next time)
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.

, 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.
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
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.
Group PolicyIn the Active Directory are abailable several group scopes. The groups scope controls which objects the group can contain, limiting the objects to the same domain or permitting objects from remote domains, and controls the location in the domain or forest there the group can be used.
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.
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
All databases have a schema which is a formal definition (set of rules) which govern the database structure and types of objects and attributes which can be contained in the database. The schema contains a list of all classes and attributes in the forest.The schema keeps track of:ClassesClass attributesClass relationships such as subclasses (Child classes that inherit attributes from the super class) and super classes (Parent classes).Object relationships such as what objects are contained by other objects or what objects contain other objects.There is a class Schema object for each class in the Active Directory database. For each object attribute in the database, there is an attributeSchema object.PartitionsActive Directory objects are stored in the Directory Information Tree (DIT) which is broken into the following partitions:Schema partition - Defines rules for object creation and modification for all objects in the forest. Replicated to all domain controllers in the forest. Replicated to all domain controllers in the forest, it is known as an enterprise partition.Configuration partition - Information about the forest directory structure is defined including trees, domains, domain trust relationships, and sites (TCP/IP subnet group). Replicated to all domain controllers in the forest, it is known as an enterprise partition.Domain partition - Has complete information about all domain objects (Objects that are part of the domain including OUs, groups, users and others). Replicated only to domain controllers in the same domain. Partial domain directory partition - Has a list of all objects in the directory with a partial list of attributes for each object.The DIT holds a subset of Active Directory information and stores enough information to start and run the Active Directory service
