MAU is an acronym for Medium Attachment Unit which converts signals on an Ethernet cable to and from AUI signals. AUI may stand for: Athena User Interface. ...
On original Thicknet Ethernet, the MAU was typically clamped to the Ethernet cable.
In most modern switched or hubbed Ethernet systems, neither the MAU nor the AUI interfaces exist (apart, perhaps as notional entities for the purposes of thinking about layering the interface), and the CAT5 cable connects directly into an Ethernet socket on the host or router. For backwards compatibility with equipment which still has external AUI interfaces, MAUs still exist which can convert between the signals on Ethernet CAT5 cabling and AUI signals.
However, the tradition of using a separate low-level I/O device in networking has continued in fast optical fiber network interfaces, where the XPAK and XAUI interfaces play a similar role. Optical fibers An optical fiber is a transparent thin fiber, usually made of glass or plastic, for transmitting light. ... An expansion pack is an addition to an existing computer game. ... XAUI (a concatenation of the Roman numeral X, meaning ten, and the initials of Attachment Unit Interface) is a standard for connecting 10 Gigabit Ethernet (10GBE) ports to each other and to other electronic devices on a printed circuit board. ...
The preferred method of leaf attachment in economy binding is double-fan adhesive or side sewing, rather than sewing through the fold, and the volume is given little or no rounding and backing, producing a flat back.
In library cataloging, a discrete unit of data (word, phrase, or group of characters) constituting part of an area of description within the bibliographic record created to represent an item, for example, the publication date in the edition statement or the number of pages or plates in the physical description.
Similarly, a unit of information within a field of a record in a bibliographic database, for example, the journal title or volume number in the source field of an entry representing a periodical article.
