[Acronym] for __I__nstitute of __E__lectrical and __E__lectronics __E__ngineers
This nonprofit U.S. engineering organization develops, defines, and reviews standards within the electronics and computer science industries.
+
+Some of the IEEE standards accepted into common use:
+
+__IEEE 754__
+
+ A standard for computer manipulation of FloatingPoint numbers, rounding behaviour under various calculations etc. Commonplace on computer hardware these days, and it’s hard to believe that, before this came along, getting meaningful results from numerical calculations involved some quite amazing voodoo black magic. See the [foreword by Professor William Kahan|http://groups.google.co.nz/group/comp.lang.python/msg/5aaf5dd86cb00651] to the ''Apple Numerics Manual, 2nd ed'' (ISBN 0-201-17738-2) for descriptions of some of this.
+
+__IEEE [802]__
+
+ A grouping for a whole bunch of standards governing local-area networking, including Ethernet and Wi-Fi.
+
+ __IEEE 802.2__
+
+ The definition for the common frame format used in Ethernet, Wi-Fi and other IEEE 802 protocols.
+
+ __IEEE 802.3__
+
+ Also known as [Ethernet]. Addenda to the original (10Mb/s) spec include 802.3u (“fast” Ethernet, 100Mb/s) and 802.3z (gigabit Ethernet, 1000Mb/s).
+
+ __IEEE 802.5__
+
+ Also known as TokenRing.
+
+ __IEEE [802.11]__
+
+ A set of specifications for wireless networks, also known as [Wi-Fi]. Comes in various flavours: [802.11b] (the first popular form, on the 2.4GHz band, with a claimed bandwidth of 11Mb/s), 802.11a (on the 5GHz band, never very popular), [802.11g] (also on 2.4GHz but with claimed bandwidth up to 54Mb/s, probably the most common nowadays), 802.11n (even higher bandwidth, still not yet finalized, which hasn’t stopped vendors bringing out products conforming to “pre-N” or “draft-N” specs).
+
+ __IEEE 802.16__
+
+ Another specification for wireless networks, also known as Wi-Max. Intended for fixed locations, whereas Wi-Fi is designed to cope with communication between moving units.
+
+__IEEE 1003__
+
+ Also known as [POSIX].
+
+__IEEE 1275__
+
+ Also known as OpenFirmware.
+
+__IEEE 1394__
+
+ Also known as FireWire.
