CSMA/CD
Carrier send multiple access with collision detection. This is a medium access
control technique for bus-tree topologies.
driver
Program that enables the network operating system to communicate with LAN
network interface cards.
Ethernet
A network communication system developed and standardized by Digital, Intel,
and Xerox, using baseband transmission, CSMA/CD access, logical bus
topology, and coaxial cable. The successor IEEE 802.3 standard provides for
integration into the OSI model and extends the physical layer and media with
repeaters and implementations that operate on fiber optics, broadband, and
twisted-pair cable.
frame
A group of bits that include data plus control information. This generally refers
to a link layer (layer 2) protocol.
IEEE 802.3 standard
Standard for the physical and electrical connections in local area networks
(LANs) developed by the IEEE.
interrupt
The signal that causes a momentary switch of control from program to operating
system when input or output is required.
I/O address
The starting address for data input and output.
LED
Light-emitting diode. A semiconductor device used as an indicator or control
light in electronic hardware. The DE305 contains two LEDs on the adapter’s
front panel to indicate link or activity conditions.
