A specific instance of a distributed file system (DFS), developed at Carnegie-Mellon University (CMU), allowing multiple file systems to be shared between organizations and treated, at the user interface level, as one giant file system.
A system (not yet widely used) that allows you to work with files on a remote host as if you were working on your own host. For instance, FTP would not be required to get a file, you could simply copy it to your home directory.
A file service that joins the local file systems of several File Server machines. Files are stored (distributed) on different machines in the computer network but are accessible from all machines.
