A great part of network administration involves management of users,
computers, and groups. A successful operating system must ensure that
only properly authenticated users and computers can logon to the network
and that each network resource is available only to authorized users.
Active Directory feature provides the solution to these problems.
An active directory is a directory structure used on Microsoft Windows based computers and servers to store information and data about networks and domains. It is primarily used for online information and was originally created in 1996. It was first used with Windows 2000. An active directory (sometimes referred to as an AD) does a variety of functions including the ability to provide information on objects, helps organize these objects for easy retrieval and access, allows access by end users and administrators and allows the administrator to set security up for the directory. An AD can be defined as a hierarchical structure and this structure is usually broken up into three main categories, the resources which might include hardware such as printers, services for end users such as web email servers and objects which are the main functions of the domain and network.
When understanding active directories, it is important to know the framework that objects can be viewed at. In fact, an active directory can be viewed at either one of three levels; these levels are called forests, trees or domains. The highest structure is called the forest because you can see all objects included within the active directory. Within the Forest structure are trees, these structures usually hold one or more domains. Going further down the structure of an active directory are single domains. To put the forest, trees and domains into perspective, consider the following example.
A large organization has many dozens of users and processes. The forest might be the entire network of end users and specific computers at a set location. Within this forest directory are now trees that hold information on specific objects such as domain controllers, program data and system, among others. Within these objects are even more objects which can then be controlled and categorized. If you are a computer administrator for a large corporation or organization, you can easily update all end users computers with new software, patches and files simply by updating one object in a forest or tree.
It is important to note that active directories are a great way to organize a large organization or corporation's computers' data and network. Without an active directory, most end users would have computers that would need to be updated individually and would not have access to a larger network where data can be processed and reports can be created. While active directories can be technical to a good extent and require considerable expertise to navigate, they are essential to storing information and data on networks
