**This reduces the disk space requirements for individual systems
**Remote file sharing is transparent to user and to any applications, because these resources appear as if they were resident on local systems
**NFS provides file sharing in a heterogeeneous (many different O/S's..,unix, windows, solaris) environment, potentially containing many different operating systems.

hi guys,
i have few doubts in computer network programming. Anyone can help me.
