The word transceiver sounds awfully close to two other words: transmitter and receiver. This is because a transceiver is a combination of a transmitter and receiver. There are a variety of types of transceivers, one being an AUI transceiver.

AUI, Attachment Unit Interface, transceivers are used to connect workstations to other devices by means of an AUI port. The mechanisms that use AUI technology are routers, servers, bridges, hubs, and a range of others.

AUI transceivers can support data transfer rates and can connect to AUI ports using STP and UTP. AUI devices can transmit high quality data and are used with AUI cables.
