Network File System, an insecure but sometimes very valuable tool. Essentially, you can export a directory or directories that other computers can mount as local directory that users of your system can access locally. This can be handy for e.g., keeping a central repository of data on one server and sharing the data to other servers or extra storage. It should be noted that NFS is not a secure service and should not be done over the net in the clear. If you must use NFS, use it only between machines that are local to you.

 '''NFS''', or Network File System, is a form of network-based file system share available on almost all UNIX and Unix-like operating systems.  For those familiar with Microsoft operating systems NFS is similar to CIFS or SMB file shares.
