What is Active Directory?

Role of System Administrator

As a system administrator or as a technical support professional, you will need to have a thorough understanding of Active Directory. In this lesson, we will provide a global view of Active Directory, what it is, how it works, and how it relates to network topology. The topics discussed here will be explored in greater detail later in this course.

Overview of Active Directory

This is the Active Directory

The SlideShow below will give you a global view of Active Directory's contents.

  1. Active Directory is Windows Directory Service. It is a centralized database that contains network information.
  2. Active Directory contains information on all network resources, such as users, groups, and printers, anything that interacts and uses the network
  3. These resources are represented by objects.
  4. The objects have attributes that provide you with a way to define and access the object.
Active Directory Pictorial Description

Active Directory and Network Topology

If Active Directory has geographically different locations, you may wish to divide or partition a network into sites, which you will learn about in detail in the module that follows.
In sum, Active Directory not only lets you view the contents of a system from the most general to the most particular. It also provides you with the tools to make that information accessible, no matter what the size or configuration of your network. In subsequent lessons, we will examine the Active Directory and its structure in greater depth. In the next lesson, you will learn about the technologies supported by Active Directory.
