Glossary
BGA:
Ball Grid Array
BFSK:
binary frequency shift keying. A coding scheme for digital data.
Bit:
A unit of information used by digital computers. Represents the smallest piece of addressable memory within a
computer. A bit expresses the choice between two possibilities and is typically represented by a logical one (1) or
zero (0).
Bit Stuffing:
Insertion of a “0” bit into a data stream to cause an electrical transition on the data wires, allowing a
PLL to remain locked.
Blackberry
: A two-way wireless device (pager) made by Research In Motion (RIM) that allows users to check
e-mail and voice mail translated into text, as well as page other users of a wireless network service. It has a
miniature “qwerty” keyboard that can be used by your thumbs, and uses SMS protocol. A Blackberry user must
subscribe to the proprietary wireless service that allows for data transmission.
Bluetooth:
A short-range wireless specification that allows for radio connections between devices within a 30-foot
range of each other. The name comes from 10th-century Danish King Harald Blatand (Bluetooth), who unified
Denmark and Norway.
BPSK
: binary phase shift keying. A means of encoding digital data into a signal using phase-modulated
communications.
b/s:
Transmission rate expressed in bits per second.
B/s:
Transmission rate expressed in bytes per second.
BTB:
Branch Target Buffer
BTS
: Base Transmitter Station
Buffer:
Storage used to compensate for a difference in data rates or time of occurrence of events, when transmitting
data from one device to another.
Bulk Transfer:
One of the four USB transfer types. Bulk transfers are non-periodic, large bursty communication
typically used for a transfer that can use any available bandwidth and can also be delayed until bandwidth is
available. See also
transfer type
.
Bus Enumeration:
Detecting and identifying USB devices.
Byte:
A data element that is eight bits in size.
Capabilities:
Those attributes of a USB device that are administrated by the host.
CAS
: Cycle Accurate Simulator
CAS-B4-RAS:
See CBR.
CBR:
CAS Before RAS. Column Address Strobe Before Row Address Strobe. A fast refresh technique in which
the DRAM keeps track of the next row it needs to refresh, thus simplifying what a system would have to do to
refresh the part.
CDMA:
Code Division Multiple Access U.S. wireless carriers Sprint PCD and Verizon use CDMA to allocate
bandwidth for users of digital wireless devices. CDMA distinguishes between multiple transmissions carried
simultaneously on a single wireless signal. It carries the transmissions on that signal, freeing network room for the
