BIOS Basic Input Output System. A collection of ROM-based
code with a standard API used to interface with standard
PC hardware.
Bit Binary digit. One bit is the basic unit of binary information.
Generally, eight consecutive bits compose one byte of data.
The pattern of 0 and 1 values within the byte determines its
meaning.
Bits per Second (bps) Bits transmitted or received.

bps See Bits Per Second .
Byte On an addressable boundary, eight adjacent binary digits (0
and 1) combined in a pattern to represent a specific
character or numeric value. Bits are numbered from the
right, 0 through 7, with bit 0 the low-order bit. One byte in
memory is used to store one ASCII character.
BOOTP A protocol for remote booting of diskless devices. Assigns
an IP address to a machine and may specify a boot file. The
client sends a bootp request as a broadcast to the bootp
server port (67) and the bootp server responds using the
bootp client port (68). The bootp server must have a table of
all devices, associated MAC addresses and IP addresses.
boot or boot-up The process a computer goes through when it starts. During
boot-up, the computer can run self-diagnostic tests and
configure hardware and software.
CDMA Code Division Multiple Access. Digital cellular phone
service method that separates multiple transmissions over
a finite frequency allocation using Spread Spectrum
techniques.
CDRH Center for Devices and Radiological Health. A federal
agency responsible for regulating laser product safety. This
agency specifies various laser operation classes based on
power output during operation.
CDRH Class 1 This is the lowest power CDRH laser classification. This
class is considered intrinsically safe, even if all laser output
were directed into the eye's pupil. There are no special
operating procedures for this class.
