Glossary - 2 MC909X Mobile Computer User Guide
ANSI Terminal. A display terminal that follows commands in the ANSI standard terminal language. For example, it uses
escape sequences to control the cursor, clear the screen and set colors. Communications programs support the ANSI
terminal mode and often default to this terminal emulation for dial-up connections to online services.
ASCII. American Standard Code for Information Interchange. A 7 bit-plus-parity code representing 128 letters, numerals,
punctuation marks and control characters. It is a standard data transmission code in the U.S.
Association. The process of determining the viability of the wireless connection and establishing a wireless network's root
and designated access points. A mobile computer associates with its wireless network as soon as it is powered on or
moves into range.
Autodiscrimination. The ability of an interface controller to determine the code type of a scanned bar code. After this
determination is made, the information content is decoded.
B
Bar. The dark element in a printed bar code symbol.
Bar Code. A pattern of variable-width bars and spaces which represents numeric or alphanumeric data in machine-readable
form. The general format of a bar code symbol consists of a leading margin, start character, data or message character,
check character (if any), stop character, and trailing margin. Within this framework, each recognizable symbology uses
its own unique format. See Symbology.
Bar Code Density. The number of characters represented per unit of measurement (e.g., characters per inch).
Bar Height. The dimension of a bar measured perpendicular to the bar width.
Bar Width. Thickness of a bar measured from the edge closest to the symbol start character to the trailing edge of the same
bar.
Bit. Binary digit. One bit is the basic unit of binary information. Generally, eight consecutive bits compose one byte of data.
The pattern of 0 and 1 values within the byte determines its meaning.
Bits per Second (bps). Bits transmitted or received.
Bluetooth. A low-cost, short-range radio link between two devices. Bluetooth can replace cables and can be used to create
ad hoc networks and provide a standard way to connect devices.
Bit. Binary digit. One bit is the basic unit of binary information. Generally, eight consecutive bits compose one byte of data.
The pattern of 0 and 1 values within the byte determines its meaning.
bps. See Bits Per Second.
Byte. On an addressable boundary, eight adjacent binary digits (0 and 1) combined in a pattern to represent a specific
character or numeric value. Bits are numbered from the right, 0 through 7, with bit 0 the low-order bit. One byte in
memory is used to store one ASCII character.
BOOTP. A protocol for remote booting of diskless devices. Assigns an IP address to a machine and may specify a boot file.
The client sends a bootp request as a broadcast to the bootp server port (67) and the bootp server responds using the
bootp client port (68). The bootp server must have a table of all devices, associated MAC addresses and IP addresses.
