AUI Full Form Name
Full Form of AUI:
Attachment Unit Interface
AUI Full Form is Attachment
Unit Interface. AUI is a physical connector interface between
Computer Network Interface Card and an Ethernet Cable. It is the part of
Ethernet standard located between MAC (Media Access Control) and MAU (Media
Access Attachment Unit). It actually details how a cable would be connected to
an Ethernet card. A coaxial cable is specifying by AUI to make junction with
transceiver. AUI has a 15 pin connection that act as a signal path between a
node and transceiver.
The AUI cable is approx. 50
meters long. In practice long cables are avoided for connection as MAU and MAC
are in straight connection with each other. AUI connectors are rarely used due
to the incorporation of MAU in computers itself. An AUI connector has a clip
instead of thumbscrews that holds two connectors together. Apple Macintosh
computers introduced a modified form of AUI called AAUI in 1991 but it
discontinued in 1998. MAU is a transceiver that converts signal from Ethernet
cable to and from AUI (Attachment Unit Interface).
In the modern world neither MAU
nor AUI exists in interfaces as the cables are connected directly into an
Ethernal socket through a host or router. The drop cable is connected via AUI
port connector in NIC (Network. The other end of the cable mostly connects to
the transceiver. The transceiver is then joined to cabling using a tap which
then pierces the cable jacket and insulation in order to make a connection.
