backup Procedure by which copy of important information is saved in
case of later loss or damage to the original.
batched data Information that has been grouped with other information to
increase the efficiency of transmission or processing.
batch processing Allows the computer to perform repetitive operations
sequentially on batched data without much involvement of the
computer operator.
baud rate
Data transfer rate between the computer and the printer. The
computer and the printer must be configured at the same baud
rate, which can be set from between 300 and 19,200 baud
depending on the type of computer used. The baud rate is set
only if the serial interface is used.
bind In SNA, a request to activate a session between two logical
units and to complete the logon process.
boot To start or restart the printer.
bps
bits per second
BSC binary synchronous communication. Character–oriented
communication protocol that uses a set of special characters to
define the structure of the data transmission frame.
carriage return
Control character that, unless set to be interpreted as a line end,
causes the printer to begin printing at the left margin of the
current line.
channel Sometimes called a circuit, facility, or link. 1. In data
communications, a path or line that enables two or more
devices to communicate. 2. Path for communication between
the CPU and input/output units or between the CPU and
peripheral devices.
character code
Code (such as ASCII or EBCDIC) that assigns numerical values
to characters.
character–coded logon
In SNA, a logon statement that is encoded and transmitted as a
character string. It is also known as an unformatted logon.
character or symbol set
Particular way in which alphabetic and numeric characters and
symbols of a font are grouped. Each character set has been
designed for a special purpose. Some sets include all printable
characters found on most standard computer keyboards.
Others are intended for such applications as math, foreign
language typesetting, and law.
CME
copy modification entry
code conversion Translation of one type of character or symbol code to another.
collate
To arrange or assemble into ordered sets.
