ETHERNET TCP/IP
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

Coaxial cable
This cable contains a single wire and a radial shield to transmit information.

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.
