Active Directory stores user credentials, permissions, and other resources on a centralized and protected location. It logs all user activity and assigns or denies permissions on the network. A domain is a basic building block of the Active Directory structure and clusters computers managed by domain controllers, which are standalone servers running Active Directory services. Multiple domains can exist within a forest, which is the top-level container for an Active Directory implementation and initially contains a single root domain.

 When you create a new installation of active directory
You Create A FOREST ,
 Now another question is that what is This Thing
Called A FOREST in ADDS.
 A Forest initially is the container of single
implementation of the Active Directory and also a
domain is created with its creation and named as
