Active Directory cannot be installed on systems that aren't Microsoft. However, you can have Active Directory functionality on non-Microsoft systems by using third party software such as Samba, which runs in a Unix/Linux environment and provides the Active Directory functionality.
No, you do not. You only install Active Directory if the system is going to be a domain controller. If it is a member server or a standalone server Active Directory should not be installed.
Domain Controller
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.

The DNS Server Role and the active directory is not installed till the adds service is started on the server 2008.if the service is not started(one needs to check the option under roles of the server)the active directory installation wont happen.this feature is only in 2008 not in 2003.The active directory works as service in 2008
Active directory must be installed . Go to start->run->administrative tools->dns select forward lookup zones right click select ZONE and click on next->then select active directory integrated complete the process
Active Directory Federation Services was developed by Microsoft. It is a software component that can be installed on Windows. It is designed to maintain application security and implement federal identity.
SRV records. SRV Records are the locator records withing DNS that allow clients to locate an Active Directory domain controller or global catalog.Source: Microsoft Windows Server 2008 Active Directory Configuration Official Academic Course Textbook.

The physical component of Active directory contain all the physical subnet present in your network like domain controllers and replication between domain controllers.The logical structure of active directory include forest, domains, tree, OUs and global catalogs.Domain : a group of computer and other resources that are part of a windows server2003 network and share a common directory database.Global catalog : Global catalog used to catch information about all object in a forest , the global catalog enables users and applications to find object in an active directory domain tree if the user or application knows one or more attributes of the target object.Tree : Tree as is collection of Active directory Domain, that means the trust relationship can be used by all other domain in the forest as a means to access the domain.Organization Unit - Organization Unit is a Active directory container into which object can be grouped for per mission management.Forest : Active directory forest as due to represents the external boundary of the directory service.These are two types of active directory forest :-I) Single Forest2) Multiple forest
