Network File System

Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, allowing a user on a client computer to access files over a computer network much like local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. NFS is an open IETF standard. After the first experimental version developed in house at Sun Microsystems, all subsequent versions of the protocol are defined in a series of Request for Comments i.e. RFCs, allowing anyone to implement the protocol.
