2. Dynamic HTML (DHTML)

3. eXtesible Markup Language (XML)

Now let us "peeled" one by one of the four programming languages on the web:


1. Hyper Text Markup Language (HTML)


-----> File extension:. Html,. Htm,. HTML4


HTML language is a language that is simple and only has a little trouble. The language is the basis of the framework the Internet was invented by Tim Berners-Lee in 1989. Almost every website uses this language, either simply display texs, animation, graphic display or sound.


HTML language actually comes from the old language called SGML (Standard Generalized Markup Language). But the development of HTML has been started since about 10 years that language is introduced.


Here are srtuktur basic HTML language:


<HTML> Sign for the browser to recognize it is the language bahea html.


<HEAD> Page header information. Inside this tag we can put the tags TITLE, BASE, ISINDEX, LINK, SCRIPT, STYLE & META.


<TITLE> As the title page. Text that you put in this tag will appear in the title bar (top part browser).


<BODY> In part this is all laid attributes such as font, bgcolor, background, etc. ..


Here are examples of simple web pages:


<HTML>


<HEAD>


<TITLE> Hello world </ TITLE>


</ HEAD>


<body Bgcolor="#000000" background="images/dark.gif" text="aqua">


<p This is an example web page </ p>


</ BODY>


</ HTML>



2. Dynamic HTML (DHTML)  -----> File extension:. DHTML


DHTML is a language that can be accessed and modified by scripting languages such as VBScript, JavaScript. DHTML is often used to display animation-animation effects such as text, change colors, etc. (even for games!). The language is often also referred to as the object of the HTML version.





3. eXtensible Markup Language (XML)  -----> File Extensions:. Xml


XML is a language that is more limited than the HTML elements. With XML, people can define their own elements and then develop it.


Determining the elements themselves? Yeah, everything is centered on the Document Type Definitions or commonly abbreviated DTD. DTD was the one who has defined the start tag and end tag from an XML file so that the displayed data can be understood.





4. XHTML  -----> File Extensions:. XHTML


The language is still in development. XHTML is a combination of HTML and XML. As with XML, this language is still quite new, but expected to go very involved in coloring the world wide web in the future. More info about this language can you find on www.w3r.org.





5. Personal Home Page (PHP)  -----> File Extensions:. Php, php3, or no extension


PHP was written by Rasmus Lerdorf initially he used to record the number of visitors to the site that opens the page resume. He then rewrite the code in C-code which then makes the language richer ability.


It was only after that many pop figures who contributed to the development of PHP such as Zeev Suraski and Andi Gutmans rewrote the parsing engine that transform and create PHP version 3. PHP Apache module which later became the most frequently used. Here's an example PHP script that will display the text Hello World.


<html>


<head>


PHP <title> displays Hello World </ title>


</ Head>


<? Php


echo "Hello world <br> <h1> <br> </ h1>";


?>


</ Html>


Complete information about this language can be found at www.php.net





6. CGI (Common Gateway Interface) -----> File Extensions:. Cgi,. Pl


CGI (Common Gateway Interface) is a standard Internet's oldest and most developed as a means of passage of information from the web server into a program and returns the result to the browser.


A CGI program can be written in the following languages:


- Perl


- Java


- C, C + +


- Script-UNIX script


- Visual Basic


- MacOS or AppleScript


This is why CGI is not appropriate if it is categorized as a language for its own CGI programs can be written using a variety of languages.





7. PERL (Practical Extraction and Report Language)  -----> File Extensions:. Pl or could be anything


PERL is a high level programming language invented by Larry Wall (1987). PERL has the ability to be applied to almost any type of operating system and most importantly, perl can be obtained for FREE!


On the Web, regular perl executable is run with the CGI (Common Gateway Interface) as mkanisme to display the output text to the browser. More info on Perl and its safety can be found at www.w3.org





8. ColdFusion -----> File Extensions:. Cfm


Coldfusion is an application development system developed by Alaire. Coldfusion main components are:


1) ColdFusion Application Server


2) ColdFusion Markup Language


3) ColdFusion Studio


CFM files are stored in plain text form, as well as PERL and PHP so anyone can view the contents. More information about ColdFusion can be found at www.alaire.com





9. ASP (Active Server Page)  -----> File extension:. Asp


ASP was created specifically for Microsoft's IIS server. This language is a dynamic web programming language. ASP can be used to execute a variety of requests to a database or the commands on the local system.


Here the following simple example which will show the date and time on a web page for server-side:


<% @ Language = "VBScript"%>


<html>


<body>


<h1> Date: </ h1>


<% = Date%>


<h1> Hours </ h1>


<% = Time%>


</ Body>


</ Html>


While the same functionality in Client-Side:


<html>


<body>


<script type="text/vbscript">


document.write ("<h1> Date: </ h1>")


document.write ("<br>" & date () & "<br>)


document.write ("<h1> Hours: </ h1>")


document.write ("<br>" & time () & "<br>)


</ Script>


<body>


</ Html>







10. JAVA  -----> File Extensions: None


Read previous articles on the history of Java to get acquainted with this language.




11. JHTML  -----> File Extensions:. Jhtml

Language standard JavaSoft SUN dicptakan output to include Java in an HTML file has its own tags that are processed before sending the output to the browser. JHTML almost similar to HTML, but it has an additional tag <Java>. Here's a very, very simple example of code that will issue JHTML display "Hello World, I came from ComputerZone"


<Java>


out.print ("Hello World, I came from x7ComputerZone");


</ Java>
