Battery Backed-up Random Access Memory
Having big-endian and little-endian byte ordering capability.
A byte-ordering method in memory where the address n of a
word corresponds to the most significant byte. In an addressed
memory word, the bytes are ordered (left to right) 0, 1, 2, 3,
with 0 being the most significant byte.
Basic Input/Output System. This is the built-in program that
controls the basic functions of communications between the
processor and the I/O (peripherals) devices. Also referred to as
ROM BIOS.
Bit Boundary BLock Transfer. A type of graphics drawing
routine that moves a rectangle of data from one area of display
memory to another. The data specifically need not have any
particular alignment.
BLock Transfer
The term more commonly used to refer to a PCB (printed
circuit board). Basically, a flat board made of nonconducting
material, such as plastic or fiberglass, on which chips and
other electronic components are mounted. Also referred to as
a circuit board or card.
bits per inch
bits per second
The pathway used to communicate between the CPU,
memory, and various input/output devices, including floppy
and hard disk drives. Available in various widths (8-, 16-, and
32-bit), with accompanying increases in speed.
A high-speed memory that resides logically between a central
processing unit (CPU) and the main memory. This temporary
memory holds the data and/or instructions that the CPU is
most likely to use over and over again and avoids accessing
the slower hard or floppy disk drive.
