NAS

Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. In this context, the term "NAS" can refer to both the technology and systems involved, or a specialized computer appliance device unit built for such functionality – a NAS appliance or NAS box. NAS contrasts with block-level, storage area networks (SAN) and direct-attached storage (DAS).
