NC (Numerical Control) - a method for controlling machine tools, such as mills, using simple programs.
NEMA (National Electrical Manufacturers Association) - this group publishes numerous standards for electrical equipment.
network - a connection of typically more than two computers so that data, email, messages, resources and files may be shared. The term network implies, software, hardware, wires, etc.
NFS (Network File System) - a protocol developed by Sun Microsystems to allow dissimilar computers to share files. The effect is that the various mounted remote disk drives act as a single local disk.
NIC (Network Interface Card) - a computer card that allows a computer to communicate on a network, such as ethernet.
NIH (Not Invented Here) - a short-lived and expensive corporate philosophy in which employees believe that if idea or technology was not developed in-house, it is somehow inferior.
noise - 1. electrical noise is generated mainly by magnetic fields (also electric fields) that induce currents and voltages in other conductors, thereby decreasing the signals present. 2. a sound of high intensity that can be perceived by the human ear.
non-fatal error - a minor error that might indicate a problem, but it does not seriously interfere with the program execution.
normally opened/closed - refers to switch types. when in their normal states (not actuated) the normally open (NO) switch will not conduct current. When not actuated the normally closed (NC) switch will conduct current.
NOVRAM (NOn Volatile Random Access Memory) - memory that does not lose its contents when turned off.
NPN - a bipolar junction transistor type. When referring to switching, these can be used to sink current to ground.
NSFNET (National Science Foundation NETwork) - funded a large network(s) in USA, including a high speed backbone, and connection to a number of super computers.
