Generally, narrowband describes telecommunication that carries voice information in a narrow band of frequencies. More specifically, the term has been used to describe a specific Frequency range set aside by the U.S. FCC for mobile or radio services, typically in the 400Mhz range.
In the AIDC industry Narrow Band communications refer to Ultra High Frequency (UHF) RF.

.NET is a business strategy from Microsoft and programming support tools for Web services, with the ability to use the Web rather than your own computer for various services. Microsoft's goal is to provide users with a seamlessly interoperable and Web-enabled Interface for applications and computing devices and to make computing activities increasingly Web browser- oriented. The .NET Platform includes Servers; building- block services, such as Web-based data storage; and device software. It also includes Passport, Microsoft's fill-in-the-form-only-once identity verification service.
NIC – Network Interface Card
Each device (Node) on a network will have a NIC. The NIC is installed inside the device and serves as the Interface to the network. The NIC can be Ethernet, Token Ring, RF, or other. It provides a Real-Time dedicated connection to the network.
Every NIC in the world has a unique hardware address called a MAC (MediaAccess Control) address. This is not to be confused with an IP Address which is a logical address assigned to the NIC on each computer, printer, Router, and other devices on a local area network (LAN). Nodes may have more than one NIC installed to talk to different networks.
The NiCad battery is a type of battery commonly used in portable computers, camcorders, portable drills, hand held data collection computers, and other small battery-powered devices, having an effective and even power discharge. When compared to Nickel-Metal Hydride (
NiMH) and Lithium Ion batteries (
Li-Ion), NiCd batteries are the most susceptible to
Memory Effect and the effects of overcharging.
NiMH – Nickel Metal Hydride
The Nickel-Metal Hydride battery is a rechargeable power source used in portable computers and other devices. The Ni The Nickel-Metal Hydride battery is a rechargeable power source used in portable computers and other devices. The NiMHbattery provides up to 40 percent longer service life than Nickel-Cadmium (NiCd) batteries as well as greater charge capacity. NiMHbatteries are also used in cellular phones and camcorders. NiMHbatteries are less susceptible to Memory Effect than NiCdbatteries but more susceptible than Lithium Ion (Li-Ion) batteries.
Used in specifying Wavelengths of light. For example, a given Laser scanner might use a light source in the visible light spectrum of 670 nM.
In a network, a node is a connection point, either a redistribution point or an end point for data transmissions. In general, a node has programmed or engineered capability to recognize and process or forward transmissions to other nodes.
In an offshoot meaning, computers, printers, and other devices connected to a network are also referred to as nodes.
Nonvolatile memory is a general term for all forms of solid state (no moving parts) memory that do not need to have their memory contents periodically refreshed. This includes all forms of read-only memory (ROM) such as programmable read-only memory (PROM), erasable programmable read- only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), and Flash memory. It also includes random access memory (RAM) that is powered with a battery.
Typically, nonvolatile memory does not require constant power to maintain its data.
