Operator Guide Glossary-3
binary Numbering system based on 2 that uses only the symbols 0 and
1. Binary is used in computers and related devices since
information can be represented with electric pulses (0=off,
1=on). Most computer calculations are binary.
binary digit (bit) In the binary numbering system, either of the characters 0 or 1.
The “bit” is the base unit of information used by computers. It can
take the form of a magnetized spot, an electric pulse, or a
positive or negative charge. A sequentially stored set of bits
represents a character on a computer. Multipliers are: 1 or 0 byte
= 8,192 bits kilobyte (KB) or 1,024 bytes = 8,388,608 bits.
Computer space equivalents are: 1.5 KB = about 1 single
spaced typed page 30 KB = about 20 typed pages 150 KB =
about 100 typed pages
binary
synchronous
transmission
Data transmission in which synchronization of characters is
controlled by timing signals generated at the sending and
receiving stations.
bit Abbreviation for binary digit, the smallest unit of information
recognized by a computer. See also binary digit.
bit mapped Display image generated bit by bit for each point or dot. A
software driven scanner is used to create characters or graphics.
bitmap An electronic image. It is comprised of a matrix of picture
elements (pixels or dots), where a bit value of one means that
the picture element is imaged, and a bit value of zero means that
the picture element is not imaged. The number of picture
elements in a square area is a function of the display device
resolution.
blocking Process of combining two or more records into a single block of
data which can then be moved, operated upon, or stored, as a
single unit by the computer.
block length Number of characters or bytes contained in a block of data (the
block is treated as a unit within the computer). Block length is
usually invariable within a system and may be specified in units
such as records, words, computer words, or characters.
boot To load the initial instructions of a program into computer
memory; these instructions then direct the loading of the rest of
the program. Booting may require entry of a few commands at
the keyboard or the flip of a switch to begin the process.
bps bits per second. In serial communication, the instantaneous bit
speed with which a device or channel transmits a character.
