Java/Javascripts?

[TT661]

can someone clarigy the difference please?

Actually the only similarity between the two is the name,

Java is a programming language developed by sun which is platform independant. (That is once it is written and compiled it can be run on any machine.) The internet uses Java applets (mini applications) to add a certain functionality.

JavaScript however was developed by netscape and originally called liveScript the microsoft eqivilant to JavaScript is JScript, They are similar but not the same leading to difficulties when designing scripts. Essentially JavaScript is a scripting language (this means it does not need to be compiled but is held within the web page itself) and can perform limited tasks such as changing text when the mouse is placed over an Image etc.

Those are the basic defenitions.

XML now there's a lnaguage that need's defining. XML or eXtensible Mark-up Language is an extention of the mark up language idea.
Mark up languages use tags to describe what is shown on screen eg in HTML <TITLE> tags enclose text to be used as a title. Mark up languages were first developed for use in word processors but became the perfect language for the internet as they can be held in coded forms as with scripted languages.

XML is slightly different and is not yet at a position where it is widly supported current browsers only have a limited support for XML.

But what does XML do?

XML is really a meta-language for describing markup languages. In other words, XML provides a facility to define tags and the structural relationships between them.

that is with XML you could create a tag called DOG which always causes text to behave in a certain way. and use this tag over and over insted of using a <H1> tag for example.
