Where does googles directory listing come from?
Google's directory listing comes from it's servers. Google has huge number of servers with it. They are capable to managing Huge data.
What is the recommended tool for populating the Active Directory with data from other directory servers?
because this is important
What is GCs and Universal Groups?
Every domain controller in a forest stores three full writable directory partitions: a domain directory partition, a schema directory partition, and a configuration directory partition. A Global Catalog is a domain controller that stores these writable directory partitions, as well as a partial, read-only copy of all other domain directory partitions in the forest. The additional directory partitions are "partial" because, although they collectively contain every object in the directory, only a limited set of specific attributes are included for each object. The Global Catalog is built automatically by the Active Directory replication system.All of the directory partitions on a Global Catalog server, whether full or partial partitions, are stored in a single directory database (Ntds.dit) on that server. There is no separate storage area for Global Catalog attributes; they are treated as additional information in the domain controller directory database.When a new domain is added to the forest, the information about the new domain is stored in the configuration directory partition, which reaches the Global Catalog server (and all domain controllers) through replication of forest-wide information. When a new Global Catalog server is designated, this information is also stored in the configuration directory partition and replicated to all domain controllers in the forest.Universal Group MembershipThe reason that a Global Catalog must be available for the domain logon process is that the membership for universal groups is not stored on all domain controllers. Because the membership of all universal groups is replicated to Global Catalog servers, the complete universal group membership of a user can be determined by querying a Global Catalog server. Universal groups are available only when a domain is in native mode.During the logon process, a security token that contains the groups to which the user belongs is associated with the user. Because universal group membership is stored only on Global Catalog servers, only these servers can identify a user as having membership in a specific universal group. If a universal group is present as an access control entry in an access control list on a specific directory object, the access token associated with the user during the logon session must contain that group in order for the Allow or Deny access permission to be applied to the user. Otherwise, a user could be granted access (on the basis of another group membership) to an object that is specifically denied that user as a member of the universal group. Similarly, this user would not be able to gain access to resources to which he or she has legitimate access as a member of the universal group.
What is DSACCESS?
There are many components within Exchange that require access to Active Directory services, such as the information store and the message categorizer. The DSAccess component optimizes the communication between these components and Active Directory. The Exchange components that need to interact with Active Directory use DSAccess to retrieve Active Directory information rather than communicating directly with domain controllers and global catalog servers. As a result, DSAccess is therefore a very important part of Exchange. DSAccess is good for system performance, since it maintains a cache that effectively reduces the number of LDAP queries that these Exchange server components make to Active Directory. This is good for query speed as well as load reduction on both domain controllers and global catalog servers.

Gcs port number?
A Microsoft Active Directory (AD) Server can only answer directly queries about objects which are in its domain. When using LDAP, you may want to get information about objects in other domains or subdomains within the organization. Most AD servers, therefore, cache information from other AD servers using a facility called the Global Catalog. To query the Global Catalog on an AD server which is also a Global Catalog Server (GCS) you must connect to the GCS port, 3268 instead of to the default LDAP port.
Where the global catalog available?
The global catalog contains a complete replica of all objects in Active Directory for its Host domain, and contains a partial replica of all objects in Active Directory for every other domain in the forest. The global catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multidomain Active Directory forest. The global catalog is stored on domain controllers that have been designated as global catalog servers and is distributed through multimaster replication. Searches that are directed to the global catalog are faster because they do not involve referrals to different domain controllers. In addition to configuration and schema directory partition replicas, every domain controller in a Windows 2000 Server or Windows Server 2003 forest stores a full, writable replica of a single domain directory partition. Therefore, a domain controller can locate only the objects in its domain. Locating an object in a different domain would require the user or application to provide the domain of the requested object. The global catalog provides the ability to locate objects from any domain without having to know the domain name. A global catalog server is a domain controller that, in addition to its full, writable domain directory partition replica, also stores a partial, read-only replica of all other domain directory partitions in the forest. The additional domain directory partitions are partial because only a limited set of attributes is included for each object. By including only the attributes that are most used for searching, every object in every domain in even the largest forest can be represented in the database of a single global catalog server.
Which directory partition contains all objects in a domain?
Contains a < domain > container (for example, the abc.com container), which stores users, computers, groups, and other objects for a specific Windows domain (for example, the abc.com domain). Updates to the < domain > container are replicated to only domain controllers within the domain and to Global Catalog servers if the update is made to an attribute that is marked for replication to the Global Catalog. The < domain > container is displayed in the Active Directory Users and Computers console. The hierarchy of domain directory partitions can be viewed in the Active Directory Domains and Trusts console, where trust relationships between domains can be managed.

What is the role of a global catalog in Active Directory?
"The global catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multidomain Active Directory forest.
