An enterprise usually has multiple DCs, and each of these controllers has a copy of the main directory for the domain. Any changes made to the directory on one DC- for example, deleting a user account or changing a password are all applied to the other DCs in a domain to keep them up-to-date. Another DC called Global Catalog server stores a copy of all objects within a directory of its domain along with a partial copy of all objects of other domains within a forest.
This allows applications and users to find objects in any domain of its forest quickly. An important thing to know is that AD is exclusive to On-prem Microsoft environments. To run it in cloud Microsoft environments, you need to use Azure Active Directory, which works similar to the On-prem variant.
Azure AD and AD are different but can run together if an organization has a hybrid deployment cloud and on-prem. The values stored in each object, such as phone number, address, email, etc.
Active Directory is vital for organizations as it helps you efficiently manage company users, computers, devices, and applications. For example, IT managers can leverage Active Directory to systematically organize company data in a hierarchy structure, which states which users or computers belong to which network, or which users have access to which network resources, and so forth.
A domain controller contains many computers on the network and allows the system administrators to manage them from the central place. It is a server or computer used to authenticate other computers throughout the network. It stores the login credentials of all other computers and printers in the network.
