and BNC connectors. Sometimes called “thin Ethernet” or
“Thinnet”.
Address
A data structure used to identify a unique entity, such as a

Operation of a network on which events are initiated by a
clock signal. In such instances, individual characters are
encapsulated in control bits called
start
and
stop
charac-
ters.
Baud
Signaling speed equal to the number of signal events per
second.
Baud
is the same as
bits per second
if each signal
event represents exactly one bit.
Bc
Committed Burst rate. See
Chapter 14, Configuring
Frame Relay
.
BCN
Backward Congestion Notification. See
Chapter 14, Con-
figuring Frame Relay
.
BECN
Backward Explicit Congestion Notification. See
Chapter
14, Configuring Frame Relay
.
BootP
Bootstrap Protocol.
Broadcast packets
Packets that are sent to all devices on a network.
BPS
Bits per second. See also
