National Electrical Code (NEC)
The NEC is a set of safety standards and rules for the design and installation of electrical circuits, including network and telephone cabling.

Network Basic Input/Output System (NetBIOS)
NetBIOS is a software system originally developed by Sytek and IBM to allow a NOS to communicate with computer hardware. NetBIOS has been adopted by Microsoft Windows NT and Novell NetWare, and has become the de facto standard for application interface to all types of LANs. Thus, many LANs are described as "NetBIOS compatible."

Network File System (NFS)
NFS is a file management system commonly used in UNIX-based computer systems.
