GLOSSARY
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.
BSC binary synchronous communication. 1. Communication using
binary synchronous line discipline. 2. Uniform procedure using
a standardized set of control characters and control character
sequences for synchronous transmission of binary-coded data
between stations.
buffer Compartment of memory in which this data is stored during
transfer from one device to another. This is useful for
accumulating data into blocks before storage or processing and
for adjusting differences of speed between devices, or between a
device and a communicating facility.
Bypass Transport Optional module that moves paper from the last stacker bin to a
finishing device.
byte Fixed number of bits (in data processing, usually 8) operated
upon as a unit. A byte may represent a character, a machine
instruction, or some other logical unit of information.
character Single printable letter (A-Z), numeral (0-9), symbol (& % #), or
punctuation mark (, . ! ?) used to represent data. Characters can
also be nonprinting, such as space, tab, or carriage return.

character set Number of different characters used by a particular device,
including alphabetic, numeric, and special characters such as
symbols.
cluster Group of paper feeder trays, usually containing the same size and
type of paper (stock). Each cluster has a name, consisting of one
to six alphanumeric characters. See also stock; stockset.
CME copy modification entry. Entry modifying the output printing
characteristics of a report on a copy-to-copy basis.
code 1. Set of symbols representing data or instructions to a
computer. 2. To write a list of instructions (software) to cause
the product/system to perform specified operations.
code conversion Translation of one type of character or symbol code to another.
