| Glossary Term | Definition |
| BACKBONE | A network that interconnects other networks, employing high-speed transmission paths and often spanning a large geographic area. |
| BACKGROUND | The area surrounding a printed symbol including the spaces and quiet zones. |
| BACKCOATING | Used on a thermal transfer ribbon to prevent the ribbon from sticking to the printhead and to the substrate (media/label material). It also protects the printhead from excessive heat, static, and abrasion.|
| BANDWIDTH | The range of frequencies, expressed in hertz (Hz), that can pass over a given transmission channel. The bandwidth determines the rate at which information can be transmitted through the circuit. |
| BANDWIDTH MANAGEMENT | Functionality that allocates and manages RF traffic by preventing unwanted frames from being processed by the access point. |
| BAR | Any of the dark lines in a printed, machine-readable symbol. |
| BARCODE | An array of parallel rectangular bars and spaces arranged according to the encodation rules of a particular symbol specification in order to represent data in machine-readable form (i.e. Code 39). |
| BARCODE CHARACTER | A single group of bars and spaces which represent an individual number, letter, punctuation mark or other symbol. |
| BARCODE DENSITY | The number of characters represented in a linear unit of measure, often expressed in characters per inch (CPI). |
| BARCODE LABEL |
A label with a bar code that is suitable to be affixed to an article or item. |
| BARCODE READER | A device used to read or decode a bar code symbol. |
| BARCODE SYMBOL |
The combination of symbol characters and features required by a particular symbology, including quiet zones, start and stop characters, data characters, check characters and other auxiliary patterns, that together form a complete scannable entity (see symbol). |
| BAR HEIGHT/LENGTH | The dimension of the individual bars in a bar code symbol or in a row of a multi-row, 2-dimensional symbol that is measured perpendicular to the scanning direction (see Y dimension). |
| BAR REFLECTANCE (BR) |
The reflectance of a bar measured in a locally-selected portion of a scan profile. |
| BAR WIDTH | The transverse dimension of an individual bar in a bar code symbol that is measured parallel to the scanning direction. The number of possible width variations within a particular printed symbol depends on the symbology used (see X dimension). |
| BAR WIDTH REDUCTION | Reduction of the nominal bar width dimension on film masters or printing plates to compensate for printing gain. |
| BC/MC | Broadcast frames; Multicast frames |
| BEACON | A uniframe system packet broadcast by the AP to keep the network synchronized. A beacon Includes the Net_ID (ESSID), the AP address, the Broadcast destination addresses, a time stamp, a DTIM (Delivery Traffic Indicator Maps) and the TIM (Traffic Indicator Message). |
| BEARER BARS | A minimum of two parallel bars running the length of the top and bottom edge of a bar code. Bearer bars, if used, reduce the probability of a misread when a skewed scanning beam enters and/or leaves the symbol through the top or bottom. |
| BFA ANTENNA CONNECTOR | Miniature coaxial antenna connector manufactured by MuRata Manufacturing Corporation. |
| BI-DIRECTIONAL | Denotes that a machine-readable symbol can be read successfully in two directions either backwards or forwards. Also identifies a scanner that can operate or a bar code that can be read independent of scanning direction. |
| BIT |
Denotes a numbering system to base 2 in which numbers are expressed as combinations of the digits 0 and 1 with positional weighting based on powers of 2. In computing, these can be represented electrically by 'off' and 'on' respectively or in machine-readable symbols by narrow and wide elements or by the absence or presence of a bar module. |
