Which Active Directory term is used for a collection of network resources?

The term "Domain" in Active Directory refers to a fundamental grouping of network resources, which includes users, computers, groups, and other types of objects. A domain serves as a boundary for security and administrative decisions, establishing a framework for managing these resources within a network.

In a domain, resources can be managed as a single entity, allowing for centralized administration, authentication, and management of security policies. Each domain has its own database and maintains security and identity policies, ensuring that only authorized users can access specific resources. This structure facilitates efficient management of large networks by providing a logical organization of resources.

While other terms like "Organizational Unit," "Forest," and "Tree" relate to Active Directory, they denote different levels of hierarchy or logical grouping. Organizational Units are used for organizing users and resources within a domain, a Forest is the highest level that encompasses one or more domains, and a Tree is a collection of one or more domains that share a contiguous namespace. However, none of these terms encapsulate the concept of a collection of network resources the way a Domain does.
