Network File System (NFS) is a client-server service that allows a computer user to view and freely store or update files on a remote computer as if they were located on the user's own computer.
The NFS protocol is one of several distributed file system standards for network-attached storage (NAS).
To access data stored on another computer, the server implements NFS processes to make the data available to clients. The server administrator determines what to make available and recognizes authenticated clients.
Files are most commonly managed in a hierarchy that allows users to view files in the current directory and then navigate to any subdirectories.
