N
Network File System (NFS)
An open operating system designed by Sun Microsystems that allows all network
users to access shared files stored on computers of different types. Users can manip-
ulate shared files as if they were stored locally on the user’s own hard disk.
With NFS, computers connected to a network operate as clients while accessing
remote files, and as servers while providing remote users access to local shared files.
The NFS standards are publicly available and widely used.

applicable for this device. A master NIS server may manage multiple file sets and the
NIS domain defines which set is associated with this device.
NIS Server address

User and Group files.

a resource.

Bits that identify the read/write/execute (rwx) privileges for a UNIX file’s owner, group,
