Hierarchical Network Topology

This example was drawn on the base of the Figure 2 illustrating the "Active Directory FAQ" from the website "Information Management Systems & Services" (IMSS) of the California Institute of Technology (Caltech) campus. [imss.caltech.edu/ node/ 412]
"By using the Active Directory® Domain Services (AD DS) server role, you can create a scalable, secure, and manageable infrastructure for user and resource management, and you can provide support for directory-enabled applications, such as Microsoft® Exchange Server. ...
AD DS provides a distributed database that stores and manages information about network resources and application-specific data from directory-enabled applications. Administrators can use AD DS to organize elements of a network, such as users, computers, and other devices, into a hierarchical containment structure. The hierarchical containment structure includes the Active Directory forest, domains in the forest, and organizational units (OUs) in each domain. A server that is running AD DS is called a domain controller." [technet.microsoft.com/ en-us/ library/ 9a5cba91-7153-4265-adda-c70df2321982]
The Active Directory Domain Services diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Active Directory Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

"A hierarchical organization is an organizational structure where every entity in the organization, except one, is subordinate to a single other entity. This arrangement is a form of a hierarchy. In an organization, the hierarchy usually consists of a singular/ group of power at the top with subsequent levels of power beneath them. This is the dominant mode of organization among large organizations; most corporations, governments, and organized religions are hierarchical organizations with different levels of management, power or authority. ... Members of hierarchical organizational structures chiefly communicate with their immediate superior and with their immediate subordinates. Structuring organizations in this way is useful partly because it can reduce the communication overhead by limiting information flow; this is also its major limitation." [Hierarchical organization.

"A company's organizational chart typically illustrates relations between people within an organization. Such relations might include managers to sub-workers, directors to managing directors, chief executive officer to various departments, and so forth. When an organization chart grows too large it can be split into smaller charts for separate departments within the organization. The different types of organization charts include: Hierarchical, Matrix, Flat (also known as Horizontal)." [Organizational chart. Wikipedia]
The org chart sample "Hierarchical organization" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the 25 Typical Organizational Charts solution from the Management area of ConceptDraw Solution Park.

"Pyramids or hierarchical.
A hierarchy exemplifies an arrangement with a leader who leads other individual members of the organization. This arrangement is often associated with bureaucracy.
These structures are formed on the basis that there are enough people under the leader to give him support. Just as one would imagine a real pyramid, if there are not enough stone blocks to hold up the higher ones, gravity would irrevocably bring down the monumental structure. So one can imagine that if the leader does not have the support of his subordinates, the entire structure will collapse." [Organization. Wikipedia]

"Organizational structure affects organizational action in two big ways. First, it provides the foundation on which standard operating procedures and routines rest. Second, it determines which individuals get to participate in which decision-making processes, and thus to what extent their views shape the organization’s actions." [Organizational structure.
