An indefinite number; or, a variable that is assigned a value depending on the context.
|NACN: North American Cellular Network|
North American Cellular Network (NACN) is an organization of cellular providers that facilitates cellular calls across the country to be linked for seamless roaming.
North American Directory Forum. A group of organizations that offer public Directory Services in North America, according to the CCITT X.500 recommendations.
|NADS: North American Digital Standards|
North American Digital Standards (NADS) refers to the North America cellular standards: the first generation is TDMA and has been in service since 1992. The second generation is CDMA which was accepted by the TIA2.48 as a standard in 1992. The third generation is CDMA2000 and more.
A screen displayed in a shareware program that reminds the user to register and pay the fee. It usually appears when the program is opened or closed.
Shareware that displays a screen when the program is opened or closed that reminds the user to register and pay the fee.
Nagware, also known as annoyware, is a type of shareware software. Other types of shareware include demoware, crippleware, freeware, adware, and even spyware. Nagware reminds —or nags— the user to register it by paying a fee. It usually does this by popping up a message when the user starts the program or, worse, intermittently while the user is using the application. These messages can appear as windows obscuring part of the screen or message boxes that can quickly be closed.
Negative acknowledgement, or not acknowledged (ASCII character 21). The opposite of the ACK signal. It indicates a message was not received correctly, or that the terminal is not ready to send.
(Number Assignment Module). The component of a wireless phone that holds its telephone number and electronic serial number in memory.
|NAM: Number Assignment Module|
Number Assignment Module (NAM) is the programmable module in an AMPS analog phone used to contain the MIN, ESN, home system ID and other information.
In programming languages, name binding refers to the association of values with identifiers. An identifier bound to a value is said to reference that value. Since computers themselves have no notion of identifiers, there is no binding at the machine language level — name binding is an abstraction provided by programming languages. Binding is intimately connected with scoping, as scope determines when binding occurs.
NameD or named. A UNIX process that converts hostnames to Internet addresses for TCP/IP.
The process of mapping a name to its corresponding address. See DNS.
A program or computer that translates one type of name into another. For example, a name server receives a query about a domain name and then sends back the IP address for that domain.
Name Daemon. A UNIX process that converts hostnames to Internet addresses for TCP/IP.
|NAMPS: Narrowband Advanced Mobile Phone |
Narrowband Advanced Mobile Phone Service (NAMPS) is an improved version of AMPS systems. NAMPS is a cellular call-handling system that uses digital signalling techniques to split the existing 30 kHz wideband voice channels into three 10 kHz narrowband voice channels. The result is three times more voice channel capacity than the traditional AMPS system provides. NAMPS cellular phones are manufactured for dual mode operation, and they are compatible with traditional AMPS systems.
Not AND. A Boolean operation which is true unless both of its inputs are true. Another way of stating it: A Boolean operation which is true if any one of its inputs is false. A NAND B = NOT (A AND B) = (NOT A) OR (NOT B). This operation is used in logic gates within the computer.
A logic gate equivalent to an AND gate followed by a NOT gate. If both of its inputs are 1, its output is 0; otherwise its output is 1. NAND gates are important because all Boolean logic operations can be built out of them.
Nanika is a desktop accessory application developed by Sagawa Toyoaki. Nanika is composed of three parts: 'materia', which is the basic foundation of Nanika system; 'shell', which can be described as a skin; 'ghost', which is a pseudo-AI engine. Nanika is heavily influenced by Japanese anime, such as Kanon and Ghost in the Shell.
A hypothetic, future technology robot that is microscopic in size; one possible way of using nanotechnology.
NanoCAD is a Java applet that was intended to eventually evolve into a useful computer-aided design system for nanotechnology. While that goal has yet to come to fruition, NanoCAD has at least influenced the direction of more advanced projects such as OpenChem and Fungimol.
A proposed future computer in which some of the logic elements are single molecules.
One billionth of a meter. The wavelengths of light are measured in nanometers.
