C

A system that requests the services of another. With the aid of the service
request, the client can access objects (data) on the server. The service is
provided by the server.
Coaxial cable
This cable contains a single wire and a radial shield to transmit information.
CSMA/CD
Carrier Sense Multiple Access with Collision Detection. When a collision is
detected, all subscribers back off. After waiting a random delay time, the
subscribers attempt to re-transmit the data.
D
Data bus
see Bus.
Deterministic ETHERNET
The ETHERNET data is transferred at a defined time constant. The
ETHERNET network can be defined and calculated. A Switched
ETHERNET architecture makes this possible.
Driver
Software code which communicates with a hardware device. This
communication is normally performed by internal device registers.
E
ETHERNET
Specifies a Local Area Network (LAN), which was developed by Xerox,
Intel and DEC in the 70's. The bus access process takes place according to
the CSMA/CD method.
