GLOSSARY
GLOSSARY-2 XEROX DOCUPRINT 96/DOCUPRINT 96MX LPS SYSTEM GENERATION GUIDE
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.
bit map Visual representation of graphic images in which a bit defines a
picture element (pixel); for example, if a bit is 1, the corresponding
pixel is printed.
bit mapped Display image generated bit by bit for each point or dot. A software-
driven scanner is used to create characters or graphics.
