1. <programming> An independent piece of {software} which
	forms part of one or more larger {programs}.  Different
	languages have different concepts of a module but there are
	several common ideas.

	Modules are usually compiled seperately (in compiled
	languages) and provide an {abstraction} or information hiding
	mechanism so that a module's implementation can be changed
	without requiring any change to other modules.  In this
	respect they are similar to {objects} in an {object-oriented
	language}, though a module may contain many {procedures}
	and/or {functions} which would correspond to many objects.

	A module often has its own {name space} for {identifiers} so
	the same identifier may be used to mean different things in
	different modules.

	[Difference from {package}?].

	2. <hardware> An independent assembly of electronic components
	with some distinct function, e.g. a RAM module consisting of
	several RAM chips mounted on a small circuit board.

<jargon> To transfer data from one computer to another.
	Downloading usually refers to transfer from a larger "host"
	system (especially a {server} or {mainframe}) to a smaller
	"client" system, especially a {microcomputer} or specialised
	peripheral, and "{upload}" usually means from small to large.

	Others hold that, technically, download means "receive" and
	upload means "send", irrespective of the size of the systems
	involved.

	Note that in communications between ground and space,
	space-to-earth transmission is always "down" and the reverse
	"up", regardless of size.  So far the in-space machines have
	invariably been smaller; thus the upload/download distinction
	has been reversed from its usual sense.

<programming, library> A collection of {subroutines} and
	{functions} stored in one or more files, usually in compiled
	form, for linking with other programs.  Libraries are one of
	the earliest forms of organised {code reuse}.  They are often
	supplied by the {operating system} or {software development
	environment} developer to be used in many different programs.
	The routines in a library may be general purpose or designed
	for some specific function such as three dimensional animated
	graphics.

	Libraries are linked with the user's program to form a
	complete {executable}.  The linking may be {static linking}
	or, in some systems, {dynamic linking}.

1. <operating system, software> The sequence of states of an
	executing {program}.  A process consists of the program {code}
	(which may be shared with other processes which are executing
	the same program), private data, and the state of the
	{processor}, particularly the values in its {registers}.  It
	may have other associated resources such as a {process
	identifier}, open files, {CPU time} limits, {shared memory},
	{child processes}, and {signal handlers}.

	One process may, on some {platforms}, consist of many
	{threads}.  A {multitasking} {operating system} can run
	multiple processes {concurrently} or in {parallel}, and allows
	a process to spawn "child" processes.

	2. <business> The sequence of activities, people, and systems
	involved in carrying out some business or achieving some
	desired result.  E.g. software development process, project
	management process, configuration management process.

/uhp'lohd/ To transfer programs or data over a digital
	communications link from a smaller or peripheral "client"
	system to a larger or central "host" one.

	Opposite: {download}.

1. <storage> Integrated Drive Electronics, see {Advanced
	Technology Attachment}.

	2. <programming, tool> {integrated development environment}.

	3. <company> {Interactive Development Environments}.
