Trees and Forests in Active Directory

What is Tree:-

• Tress is a set of one or more domains with contiguous names.

• If more than one domain exists, you can combine the multiple domains into hierarchical tree structures.

• The first domain created is the root domain of the first tree.

• Other domains in the same domain tree are child domains.

• A domain immediately above another domain in the same domain tree is its parent.

 What is Forest:-

• Multiple domain trees within a single forest do not form a contiguous namespace.

• Although tree in a forest do not share root a namespace, a forest will have a single root domain, called the forest root domain.

• The forest root domain is the first domain created in the forest.

• These two forest-wide predefined groups reside in forest root domain.
