This AD diagram example was created based on the picture "AD LDS as a phone book service" from the book "Active Directory for Dummies".
"Directory services are a great way of providing information that can be fre-
quently retrieved and searched on in a hierarchical way. ... Well, there’s no reason that you can’t create a directory service that’s actually a phone book. Imagine that you need to make a searchable phone directory of your organization available on the Internet. ... This isn’t a difficult task, but it has security repercussions. If you’ve already deployed AD DS and you have the employees’ phone numbers available in that directory, it might not be a good idea to expose your AD DS environment to the Internet for security reasons. Using AD LDS is a great alternative because it can be deployed separately from AD DS and it’s designed to simply provide the information retrieval service that you need without the complications involved with Kerberos authentication and group policies."

"Satellite television is television programming delivered by the means of communications satellite and received by an outdoor antenna, usually a parabolic reflector generally referred to as a satellite dish, and as far as household usage is concerned, a satellite receiver either in the form of an external set-top box or a satellite tuner module built into a TV set. Satellite TV tuners are also available as a card or a USB peripheral to be attached to a personal computer. In many areas of the world satellite television provides a wide range of channels and services, often to areas that are not serviced by terrestrial or cable providers.
Direct-broadcast satellite television comes to the general public in two distinct flavors - analog and digital. This necessitates either having an analog satellite receiver or a digital satellite receiver. Analog satellite television is being replaced by digital satellite television and the latter is becoming available in a better quality known as high-definition television." [Satellite television.

"Microsoft Windows 2000 Server introduces Active Directory to replace domain functionality. Active Directory will continue to get the job done, but in a much more efficient way. Active Directory can be replicated between multiple domain controllers, so no single system is critical. In this way, the crucial data stored within Active Directory is both redundant and load-balanced.
A directory, in the most generic sense, is a comprehensive listing of objects. A phone book is a type of directory that stores information about people, businesses, and government organizations. Phone books typically record names, addresses, and phone numbers. Active Directory is similar to a phone book in several ways, and it is far more flexible. Active Directory will store information about organizations, sites, systems, users, shares, and just about any other network object that you can imagine. Not all objects are as similar to each other as those stored in the phone book, so Active Directory includes the ability to record different types of information about different objects."
