The ratio between the widths of wide elements and narrow elements in a two-width symbology.
named pipe
A high-level interprocess communication facility that allows bidirectional, multipoint communications between processes. In an OS/2 LAN Server environment, named pipes may also be used to communicate across the LAN. Remote named pipes use NETBIOS as the underlying communications protocol.
A unit of measure used to define the wavelength of light. Equal to 10-9 meters.
Network addressable unit. A network address that allows a device to communicate with IBM hosts in a 3270 network.
Negative acknowledgment character. Indicates a negative acknowledgment to a solicitation event or a data transmission event.
net data density
In a linear bar code symbol, the number of characters in the symbol divided by the overall symbol length, measured from the leading edge of the start code to the trailing edge of the stop code.
1. Network communications process. Enables communication between DCM and remote application programs. NetComs are necessary when the target application is operating on a node that DCM does not reside on (remote node.) 2. Applications communicate with the Model 200 Controller through network communications processes called NetComms. NetComms are responsible for safely routing data from remote applications across a network to the controller and back.
A collection of devices that can store and manipulate electronic data, interconnected in such a way that their users can store, retrieve, and share information with each other.
network administrator
The person who is responsible for the installation, management, and control of a network.
network ID
A number used by a device during channel search to locate the controller's RFNC address.
network interface card
NIC. An adapter card that is installed in the controller that allows it to connect to a network (for example, Ethernet, Token Ring, Twinaxial). The card contains both the hardware to accommodate the cables and the software to use the network's protocols. The NIC is also called a network adapter card.
network node
An end point in a network to which or from which data can be routed. Usually this is a workstation or host.
A software term that refers to the practice of grouping bits into sets of four, which are called nibbles. Usually bits are grouped into sets of eight, which are called bytes.
NiCad backup battery
The terminal contains a rechargeable NiCad backup battery that is designed to back up all memory and the real-time clock while you change the lithium-ion main battery pack. The NiCad battery will provide backup battery power for a maximum of 1 month if a fully-charged main battery pack is installed, or for a maximum of 3 days if a main battery pack is not installed.
NiCad battery pack
Provides the main power source to operate the reader. The battery pack contains rechargeable nickel-cadmium (NiCad) battery cells.
National Language Support. A DOS feature that provides country-specific information and character set (code page) switching for international language support.
The exact (or ideal) intended value for a specified parameter. Tolerances are specified as positive and negative deviations from this value.
In a bar code system, the absence of data output after an attempted scan due to no code, defective code, scanner failure, or operator error.
Refers to memory that is saved when power is lost or turned off. See also volatile.
Novell user name
Parameter that identifies the user to the Novell software running on a remote host.
null modem cable
A cable that connects two computers and allows transmission of data between them without requiring a modem.
A character set that includes only numbers.
number pad
A set of keys on the reader that allows you to move the cursor around the screen and to type numbers and mathematical symbols. The reader's number pad is designed to work like the number pad on a regular PC keyboard.
