Glossary
This appendix contains a list of conventional communications terms.
Adapter Name A name assigned to locally identify a module (e.g., an Ethernet Interface) in the
local station. (See also Network Address Name.)
Address Administration The assignment of LAN addresses locally or on a universal basis.
Address Field The part of a Protocol Data Unit (PDU) that contains an address.
Address Resolution Protocol (ARP) The Internet Protocol that binds dynamically a high-level
Internet Address to a low-level physical hardware address such as a MAC address.
Advanced User Parameters (AUP) .....
Apple Attachment Unit Interface (AAUI) A lower power, smaller connector adaptation of the
IEEE 802.3 AUI.
Attachment Unit Interface (AUI) In a network node on a Local Area Network, the interface
between the medium attachment unit (MAU) and the data terminal equipment. Often called
“transceiver cable”.
AUI/AAUI Port A connector on the network interface.
AUI/AAUI Cable The cable between the AUI/AAUI port and the transceiver (some transceivers
plug directly into the AUI/AAUI port, thus requiring no separate cable).
AUP See Advance User Parameters.
BOOTP BOOTP is a bootstrap protocol that allows a TCP/IP network node (such as a Series 90
PLC with Ethernet Interface) to discover its own IP address and other configuration
information. This information is supplied from a BOOTP Server device on the network.
Bridge A functional unit that interconnects two Local Area Networks (LANs) that use the same
logical link control protocol, but may use different medium access control protocols. A
bridge connects network nodes at the Data Link Layer, ISO layer 2.
Broadcast Sending of a frame that is intended to be accepted by all other nodes on the same
Local Area Network.
Broadcast Address A LAN group address that identifies the set of all nodes on a Local Area
Network.
Bus Network A Local Area Network in which there is only one path between any two network
nodes and in which data transmitted by any node is available to all other nodes connected to
the same transmission medium. NOTE: A bus network may be linear, star, or tree topology.
