(Common Internet File System) The file sharing protocol used in Windows. It evolved out of the SMB (Server Message Block) protocol in DOS, which is why the terms CIFS/SMB and SMB/CIFS are sometimes seen. The word "Internet" in the CIFS name has little relevance. It stems back to the 1996/97 time frame when Microsoft submitted CIFS to the IETF, but that draft has expired. See file sharing protocol, SMB and Samba.
