Questions tagged [nfs]

Network File System (NFS) is a network file system protocol originally developed by Sun Micro systems in 1984, allowing a user on a client computer to access files over a network in a manner similar to how local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. The Network File System is an open standard defined in RFCs.
