Network-based file systems can be accessed over the network. Typically, network-based file systems reside on one system, typically a server, and are accessed by other systems across the network. NFSTM is the only available network-based or distributed computing file system.
With NFS, you can administer distributed resources (files or directories) by exporting them from a server and mounting them on individual clients. See "The NFS Environment" for more information.
