Broadband:
A data transmission technique allowing multiple high-speed signals to share the bandwidth of a single
cable via frequency division multiplexing.
Broadband Network:
A network that uses multiple carrier frequencies to transmit multiplexed signals on a single cable.
Several networks may coexist on a single cable without interfering with one another.
Brouter:
A device that routes specific protocols, such as TCP/IP and IPX, and bridges other protocols, thereby
combining the functions of both routers and bridges.
Bus:
A LAN topology in which all the nodes are connected to a single cable. All nodes are considered equal
and receive all transmissions on the medium.
Byte:
A data unit of eight bits.
Channel:
The data path between two nodes.
CHAP:
(Challenge Handshake Authentication Protocol) Authentication scheme for PPP where the password
not only is required to begin connection but also is required during the connection - failure to provide
correct password during either login or challenge mode will result in disconnect.
Coaxial Cable:
An electrical cable with a solid wire conductor at its center surrounded by insulating materials and an
outer metal screen conductor with an axis of curvature coinciding with the inner conductor - hence
"coaxial." Examples are standard Ethernet cable and Thinwire Ethernet cable.
Collision:
The result of two network nodes transmitting on the same channel at the same time. The transmitted
data is not usable.
Collision Detect:
A signal indicating that one or more stations are contending with the local station's transmission. The
signal is sent by the Physical layer to the Data Link layer on an Ethernet/IEEE 802.3 node.
