1. The {supervisor} program or {operating system} on a
	computer.

	2. The entire computer system, including input/output devices,
	the {supervisor} program or {operating system} and possibly
	other {software}.

	3. Any large program.

	4. Any method or {algorithm}.

	[{Jargon File}]

A processor's clock or one {cycle} thereof.  The relative
	execution times of instructions on a computer are usually
	measured by number of clock cycles rather than seconds.  One
	good reason for this is that {clock rates} for various models
	of the computer may increase as technology improves, and it is
	usually the relative times one is interested in when
	discussing the {instruction set}.

1. A new or better version of some {hardware} or {software}.

	Often used in {marketroid}-speak to mean "{bug fix}".

	2. The act of developing or installing a new version.

What many users feel for computers.

	"I don't really love computers, I just say that to get them
	into bed with me". (Terry Pratchet)

<operating system> (From {boot}) A {boot} with the implication
	that the computer has not been down for long, or that the
	{boot} is a {bounce} intended to clear some state of
	{wedgitude}.

	See {warm boot}.

<messaging> One of {Usenet}'s huge collection of topic groups
	or {fora}.  {Usenet} groups can be "unmoderated" (anyone can
	post) or "moderated" (submissions are automatically directed
	to a {moderator}, who edits or filters and then posts the
	results).  Some newsgroups have parallel {mailing lists} for
	{Internet} people with no netnews access, with postings to the
	group automatically propagated to the list and vice versa.
	Some moderated groups (especially those which are actually
	gatewayed {Internet} {mailing lists}) are distributed as
	"{digests}", with groups of postings periodically collected
	into a single large posting with an index.

	Among the best-known are comp.lang.c (the {C}-language forum),
	comp.arch (on computer architectures), comp.Unix.wizards (for
	{Unix wizards}), rec.arts.sf-lovers (for science-fiction
	fans), and talk.politics.misc (miscellaneous political
	discussions and {flamage}).

	Barry Shein <bzs@world.std.com> is alleged to have said,
	"Remember the good old days when you could read all the group
	names in one day?"  This gives a good idea of the growth and
	size of {Usenet}.

	See also {netiquette}.

	(1994-12-13)

A message sent to a {newsgroup} or {mailing list} (may also be
	called "a post") or the act of sending it.  Distinguished from
	a "letter" or ordinary {electronic mail} message by the fact
	that it is broadcast rather than point-to-point.  It is not
	clear whether messages sent to a small mailing list are
	postings or e-mail; perhaps the best dividing line is that if
	you don't know the names of all the potential recipients, it
	is a posting.
