A distributed data store is a computer network where data is stored on more than one single node, very much in a replicated manner. It is explicitly referred to as either a distributed database (wherein users can store information on a number of nodes) or a computer network (wherein users store information on a number of peer network nodes).

- Distributed database: It is a database in which storage devices are not at all connected to a CPU and are controlled by a distributed database management system (collectively at times known as distributed database system). It is either stored in different computers placed in the same physical location or disseminated over a network of unified computers. Contrasting to parallel systems, wherein the processors are closely attached to create a single database system. Distributed database system comprises of slackly-tied sites that share any physical components.

- Peer network node data stores: In it, the end-user can share and permit other users to use their computer as a storage node. Data may or may not be openly accessible to other users contingent on the network design.

Distributed data stores basically use an error detection and correction method. But, there are some distributed data stores which use forward error correction provisions to pull through the original file when any portion of the file is either damaged or inaccessible.
