auxiliary menu
Menu that contains options not displayed in a window. The symbol
for an auxiliary menu is a box containing three horizontal lines.
B4
Paper size measuring 250 by 353 mm.
background job
Low-priority job, usually batched, that is executed automatically as
system resources become available.
backup file
File copied to a storage medium for safekeeping in case the original
is damaged or lost.
band
Rectangular area in printer memory into which an image sent to the
printer from a computer is divided.
batch processing
Allows for repetitive operations to be performed sequentially on
batched data without much involvement of the computer operator.
baud
Measurement of data rate in bits per second. This term is used to
describe information flow between two devices. Unit of data
transmitting and receiving speed is roughly equal to a single bit per
second. Common baud rates are 110, 300, 1200, 2400, 4800, and
9600.
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.
