<language, text> An {SGML}, {HTML}, or {XML} {token}
	representing the beginning (start tag: "<p ...>") or end (end
	tag: "</p>") of an {element}.  In normal SGML {syntax} (and
	always in {XML}), a tag starts with a "<" and ends with an
	">".

	In {HTML} jargon, the term "tag" is often used for an
	"{element}".

<programming> (Or "procedure") A sequence of {instructions}
	for performing a particular task.  Most programming languages,
	including most {machine languages}, allow the programmer to
	define subroutines.  This allows the subroutine code to be
	called from multiple places, even from within itself (in which
	case it is called {recursive}).  The programming language
	implementation takes care of returning control to (just after)
	the calling location, usually with the support of call and
	return instructions at {machine language} level.

	Most languages also allow {arguments} to be passed to the
	subroutine, and one, or occasionally more, {return values} to
	be passed back.

	A {function} is often very similar to a subroutine, the main
	difference being that it is called chiefly for its return
	value, rather than for any {side effects}.

<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.

	(2000-04-08)

1. <hardware> {monitor}.

	2. <language> A vector of pointers to {activation records}.
	The Nth element points to the activation record containing
	variables declared at {lexical depth} N.  This allows faster
	access to variables from outer {scopes} than the alternative
	of linked activation records (but most variable accesses are
	either local or global or occasionally to the immediately
	enclosing scope).  Displays were used in some {ALGOL}
	implementations.

<database> A collection of {records} in a {relational database}.

	(1997-06-04)

1. <database> One or more large structured sets of persistent
	data, usually associated with software to update and {query}
	the data.  A simple database might be a single file containing
	many {records}, each of which contains the same set of
	{fields} where each field is a certain fixed width.

	A database is one component of a {database management system}.

	See also {ANSI/SPARC Architecture}, {atomic}, {blob}, {data
	definition language}, {deductive database}, {distributed
	database}, {fourth generation language}, {functional
	database}, {object-oriented database}, {relational database}.

	2. <hypertext> A collection of {nodes} managed and stored in
	one place and all accessible via the same {server}.  {Links}
	outside this are "external", and those inside are "internal".

	On the {World-Wide Web} this is called a {website}.

	3. All the facts and rules comprising a {logic programming}
	program.

<programming, World-Wide Web> (JSP) A freely available
	specification for extending the {Java Servlet} {API} to
	generate dynamic {web pages} on a {web server}.  The JSP
	specification was written by industry leaders as part of the
	Java development program.

	JSP assists developers in creating {HTML} or {XML} pages that
	combine static (fixed) page templates with dynamic content.
	Separating the {user interface} from content generation allows
	page designers to change the page layout without having to
	rewrite program code.  JSP was designed to be simpler than
	pure servlets or {CGI} {scripting}.

	JSP uses XML-like tags and scripts written in Java to generate
	the page content.  HTML or XML formatting {tags} are passed
	back to the client.  Application logic can live on the server,
	e.g. in {JavaBeans}.

	JSP is a {cross-platform} alternative to {Microsoft's} {Active
	Server Pages}, which only runs in {IIS} on {Windows NT}.

	Applications written to the JSP specification can be run on
	compliant web servers, and web servers such as {Apache},
	{Netscape Enterprise Server}, and Microsoft {IIS} that have
	had Java support added.  JSP should soon be available on
	{Unix}, {AS/400}, and {mainframe} platforms.

<security> An arbitrary string of characters chosen by a user
	or {system administrator} and used to authenticate the user
	when he attempts to log on, in order to prevent unauthorised
	access to his account.

	A favourite activity among unimaginative {computer nerds} and
	{crackers} is writing programs which attempt to discover
	passwords by using lists of commonly chosen passwords such as
	people's names (spelled forward or backward).  It is
	recommended that to defeat such methods passwords use a
	mixture of upper and lower case letters or digits and avoid
	proper names and real words.  If you have trouble remembering
	random strings of characters, make up an acronym like
	"ihGr8trmP" ("I have great trouble remembering my password").
