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.
