Specific computer hardware, as in the phrase
	"platform-independent".  It may also refer to a specific
	combination of hardware and {operating system} and/or
	{compiler}, as in "this program has been ported to several
	platforms".  It is also used to refer to support software for
	a particular activity, as in "This program provides a platform
	for research into routing protocols".

<unit> (fps) The unit of measurement of the {frame rate} of a
	moving image.

<jargon> 1. A piece of {hardware} that encapsulates some
	function but can't be used without some kind of {front end}.
	Today we have, especially, "{print engine}": the guts of a
	{laser printer}.

	2. An analogous piece of software; notionally, one that does a
	lot of noisy {crunching}, such as a "database engine", or
	"{search engine}".

	The hackish senses of "engine" are actually close to its
	original, pre-Industrial-Revolution sense of a skill, clever
	device, or instrument (the word is cognate to "ingenuity").
	This sense had not been completely eclipsed by the modern
	connotation of power-transducing machinery in {Charles
	Babbage}'s time, which explains why he named the
	stored-program computer that he designed in 1844 the
	"{Analytical Engine}".

/de'moh/ 1. A demonstration of a product, often of an early
	version or prototype.  A demo is a far more effective way of
	inducing bugs to manifest themselves than any number of {test}
	runs, especially when important people are watching.

	2. {demo version}.

	3. A program written to demonstrate the programmer's coding
	ability and/or the power of the computer it runs on.  Such
	demos are nearly always written in {machine code} and
	traditionally feature scrolling text about the author, his
	friends, his code and anything else he fancies and animated
	graphics.

See also {complete graph}, {complete inference system},
	{complete lattice}, {complete metric space}, {complete partial
	ordering}, {complete theory}.

<software> Instructions for a computer in some programming
	language, often {machine language}.  The word "code" is often
	used to distinguish instructions from {data} (e.g. "The code
	is marked 'read-only'") whereas "{software}" is used in
	contrast with "{hardware}" and may consist of more than just
	code.

1. <database> {inner join} (common) or {outer join} (less
	common).

	2. <theory> {least upper bound}.

	(1998-11-23)

1. <unit, text> (Sometimes abbreviated "pt") The unit of
	length used in {typography} to specify text character height,
	{rule} width, and other small measurements.

	There are six slightly different definitions: {Truchet point},
	{Didot point}, {ATA point}, {TeX point}, {Postscript point},
	and {IN point}.

	In Europe, the most commonly used is Didot and in the US, the
	formerly standard ATA point has essentially been replaced by
	the PostScript point due to the demise of traditional
	typesetting systems and rise of desktop computer based systems
	running software such as {QuarkXPress}, {Adobe InDesign} and
	{Adobe Pagemaker}.

	There are 20 {twips} in a point and 12 points in a {pica}
	(known as a "Cicero" in the Didot system).

	{Different point systems
	(http://www.vakcer.com/oberon/dtp/fonts/point.htm)}.

	(2004-12-23)

	2. <hardware> To move a {pointing device} so that the
	on-screen pointer is positioned over a certain object on the
	screen such as a {button} in a {graphical user interface}.  In
	most {window systems} it is then necessary to {click} a
	(physical) button on the pointing device to activate or select
	the object.  In some systems, just pointing to an object is
	known as "mouse-over" {event} which may cause some help text
	(called a "tool tip" in {Windows}) to be displayed.

	(2001-05-21)

1. <networking> {network}.

	2. <networking> {network, the}.

	3. <architecture> {neural network}.

	4. <networking> The {top-level domain} originally for
	networks, although it sees heavy use for {vanity domains} of
	all types.

	(1999-01-26)

A string-oriented language designed to support the
	construction of {Modula-3} programs from {modules}, interfaces
	and libraries.  Written by Stephen Harrison of DEC SRC, 1993.
