'''Network File System''' ('''NFS''') is a protocol originally developed by [[Sun Microsystems]] in [[1984]] and defined in [[Request for Comments|RFC]] 1094, 1813, (3010) and 3530, a [[file system]] which allows a [[computer]] to access files over a [[network]] as if they were on its local disks.

The original versionsVersions 2 and 3 of the protocol used the [[User Datagram Protocol]] (UDP) and were meant to keep the protocol [[stateless]], with [[Lock (software engineering)|locking]] (for example) implemented outside of the core protocol. Version 4 includedincludes performance improvements and introducedintroduces a [[State (computer science)|stateful]] protocol. It has thus been possible to use NFS over [[TCP]] since version 3.

NFS is strongly associated with [[UNIX]] systems, though it can be used on any platform such as [[Macintosh]] and [[Microsoft Windows]] [[operating systems]]. The [[server message block]] (SMB), a similar protocol, is the equivalent implementation of a [[network file system]] under Microsoft Windows.

The term "network file system" is also often used as a generic term — see [[file system]] for other examples.
