Baseband LAN:
A LAN that uses a single carrier frequency over a single channel. Ethernet, Token Ring and Arcnet
LANs use baseband transmission.
Baud:
Unit of signal frequency in signals per second. Not synonymous with bits per second since signals can
represent more than one bit. Baud equals bits per second only when the signal represents a single bit.
Binaries:
Binary, machine readable forms of programs that have been compiled or assembled. As opposed to
Source language forms of programs.
Binary:
Characteristic of having only two states, such as current on and current off. The binary number system
uses only ones and zeros.
Bit:
The smallest unit of data processing information. A bit (or binary digit) assumes the value of either 1
or 0.
Block
A block is a variable-size piece of memory that a task can acquire. Blocks are allocated from heaps.
[Related: Buffer, heap]
BNC:
A standardized connector used with Thinnet and coaxial cable.
BOOTP:
A TCP/IP network protocol that lets network nodes request configuration information from a BOOTP
"server" node.
bps:
Bits per second, units of transmission speed.
Bridge:
A networking device that connects two LANs and forwards or filters data packets between them, based
on their destination addresses. Bridges operate at the data link level (or MAC-layer) of the OSI
reference model, and are transparent to protocols and to higher level devices like routers.
