whats difference between domain partition and application directory partition

Can someone tell me the difference between them ..


where do each partition data stores in the server...

All directory data is stored in the Active Directory database ntds.dit.

Within the database, data is split into partitions. The domain partition holds data about objects in the domain, e.g. groups, users, computers and the domain partition is replicated to all domain controllers in the domain.

The schema partition and configuration partition are replicated to every domain controller in the forest, although only the server that holds the Schema Master FSMO role can write to the schema partition.

Application directory partitions store data specific to applications, such as DNS, and do not have to be replicated domain or forest wide. For example, if you have three domain controllers and only two of them are DNS servers, then the application directory partition will only replicate between the two DNS servers.

This is the TechNet article on how the data store works.
