Application Directory Partition is a partition space in Active Directory which an application can use to store that application specific data. This partition is then replicated only to some specific domain controllers. The application directory partition can contain any type of data except security principles (users, computers, groups).

yes all the DCs have full information about different partions except for application partion The dcs which have application partition activated can get additional updates for it.
Application PartitionApplication partitions store information about application in Active Directory. Each application determines how it stores, categorizes, and uses application specific information. To prevent unnecessary replication to specific application partitions, you can designate which domain controllers in a forest host specific application partitions. Unlike a domain partitions, an application partition cannot store security principal objects, such as user accounts. In addition, the data in an application partition is not stored in the global catalog.As an example of application partition, if you use a Domain Name System that is integrated with Active Directory you have two application partitions for DNS zones -- ForestDNSZones and DomainDNSZones:ForestDNSZones is part of a forest. All domain controllers and DNS servers in a forest receive a replica of this partition. A forest-wide application partition stores the forest zone data.DomainDNSZones is unique for each domain. All domain controllers that are DNS servers in that domain receive a replica of this partition. The application partitions store the domain DNS zone in the DomainDNSZones.Each domain has a DomainDNSZones partition, but there is only one ForestDNSZones partition. No DNS data is replicated to the global catalog server.
At Active Directory configuration partition
Active Directory data is logically partitioned so that each domain controller does not store all objects in the directory. Each directory partition, also called a naming context, contains objects of a particular scope and purpose. Below are the three major Active Directory partitions described:-· Schema Partition defines the object classes and their attributes for the entire directory. The configuration is replicated to everydomain controller in the forest.· Domain Partition contains all the objects stored in a domain, including users, groups, computers, and group policy containers (GPCs). This partition information is replicated to all domain controllers within a domain, but not to domain controllers in other domains.· Configuration Partition contains objects that represent the logical struct-er of the forest, domains, as well as the physical topology, including sites, subnets, and services.Application Directory Partition replicates directory partition only to specific domain controllers. This is responsible for generating and maintaining Replication topology. Objects stored in Application directory partition are not replicated to the Global Catalog.
The Schema and Configuration partition
Boot.ini file is stored in the root directory of the active partition. pag 786
Two DNS application directory partitions below the forest root domain are automatically created by the DNS Server service when the computer restarts after the Active Directory Installation Wizard has finished. One application directory partition is created for the forest, ForestDnsZones, and one for the domain, DomainDnsZones. You can use the DNS administrative tool or the dnscmd.exe command-line tool, located in the \Support\Tools directory on the Windows Server 2003 product CD, to use these application directory partitions for DNS zone storage. If you are installing an additional domain controller in an existing forest, the domain controller holding the domain naming operations master role must be online, available, and running Windows Server 2003 for these application directory partitions to be created. If the domain naming master is unavailable or is running Windows 2000, the DNS Server service will attempt to create the application directory partitions again at a later time.
