Glossary of Terms
AUI Port The connector on the network interface.
AUI Cable The cable between the AUI port and the transceiver (some transceivers plug directly into the AUI port, thus requiring no separate AUI cable).
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 The Internet Protocol that binds dynamically a
Apple Attachment Unit Interface (AAUI) A lower power, smaller connector adaptation of the IEEE 802.3 AUI.
ASCII Code The American Standard Code for Information Interchange is an information code standard by which digits, letters, symbols and control characters can be encoded as numbers.
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 ªtransceiver cableº.
Bit Contraction of Binary Digit. The smallest unit of memory. Can be used to store one piece of information that has only two possible states or values (e.g., One/Zero, On/Off, Yes/No). Data that requires more than two states or values (e.g., numerical values) requires multiple bits (see Word).
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, the address of a file server host, and the name of a file to be loaded into memory and executed.
Broadcast Address A LAN group address that identifies the set of all nodes on a Local Area 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.
Broadcast Sending of a frame that is intended to be accepted by all other nodes on the same 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 immediately to all other nodes connected to the same transmission medium. NOTE: A bus network may be linear, star, or tree topology.
