C
Client
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.
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.
DHCP
Dynamic Host Configuration Protocol. This protocol allows to configure the
network of a computer automatically as well as to assign addresses or to set
parameters. The DHCP uses a fixed IP address pool when assigning a
temporary IP address to a networked computer (client). This is done
automatically and saves a lot of network configuration work. The client also
obtains other information, such as the gateway address (router) and the IP
address of the name server (DNS).
