In common usage, NFS is more commonly used as the name of the network filesystem &#x2F; protocol, like ZFS, XFS, and FAT are the names of local filesystems. They all have official expansions, but  nobody talks about, say, the &quot;File Allocation Table&quot; filesystem.<p>It is <i>not</i> being used here as an acronym for the general concept of network file systems. It&#x27;s a specific filesystem&#x2F;protocol named &quot;NFS&quot;, originally the Sun Network Filesystem.
