Some of the IEEE standards accepted into common use:
__IEEE 754__
- A standard for computer manipulation of floating-point
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 to the ''Apple Numerics Manual, 2nd ed'' (ISBN -201-17738-2) for descriptions of some of this.

__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).
