Analog Output Module
A module that outputs a signal proportional to a number transferred to the
module from the processor.
Arithmetic Capability
The ability to do addition, subtraction, multiplication, division, and other
advanced math functions with the processor.
ASCII
American Standards Code for Information Interchange. It is a 7-bit code
with an optional parity bit used to represent alphanumerics, punctuation
marks, and control code characters.
Asynchronous
Recurrences or repeated operations that take place in patterns unrelated
over time.
Asynchronous Shift Register
A shift register that is loaded and or unloaded based on external conditions
and/or timing function.
Attribute
A means of flashing, underlining, and or blinking data on a display device.
Backplane
A printed circuit board, located in the back of a chassis, that contains a data
bus, power bus, and mating connectors for modules to be inserted in
the chassis.
Battery Backup
A battery or set of batteries that provides power to processor memory only
in case of a system power outage.
Battery Low
A condition that exists when the backup battery voltage drops low enough
to require battery replacement.
Baud
(1) A unit of data transmission speed equal to the number of code
elements (bits per second). (2) A unit of signalling speed equal to the
number of discrete conditions or signal events per second.
BCD
See Binary Coded Decimal.
Binary
A numbering system using only the digits 0 and 1. Also called base-2.
