 ## NFS
 
-NFS is an acronym for Network File System. It allows the sharing of files and folders over a network with other systems. NFS provides a simple way for making the contents of the local file system available to multiple users (or systems) on a network.

 This sharing is traditionally between UNIX/Linux like systems, but systems running Microsoft Windows operating systems can also access NFS shares if they have the proper software installed to do this. 
 
 Support for NFS must be enabled or compiled into the kernel. 
 
-As with most networking concepts, there is a client side and a server side to NFS. The server side consists of the system that exports (shares) file systems to other systems. The client side consists of the systems that needs access to file system exported by the server.
