Whats the difference between HTML, PHP, ASP, XML, CSS, and what are their uses?

HTML - stands for Hypertext Markup Language. Web pages ware created with HTML. HTML "tags" are used to tell your browser how text should be displayed on your screen.





PHP - stands for PHP: Hypertext Preprocessor. This is script sitting in the web server. When request information from the server calling a php. The php will create HTML page based upon your request. This is why PHP is called server side scripting language.





ASP - stands for Active Server Page. Some purpose as PHP. This language has been developed by Microsoft.





XML - stands for eXtensible Markup Language. A common misunderstanding is that XML is newer version of HTML. Not true. HTML tells the browser how to display the text, whereas, XML is used to determine how data is being stored. We know that a persons name consists of a first name and a last name -- XML can be used to enforce that hierarchy of data.





CSS - stands for Cascaded Style Sheet. CSS is modifies HTML or XML to apply a style to the displayed page.





This is a very simplistic explanation. Search the internet to find more about them.

who really knows
Reply:This is really a broad question, but the common theme for all of these is web programming:





1. Hypertext Markup Language


2. Hypertext Preprocessor


3. Active Server Pages


4. Extensible Markup Language


5. Cascading Style Sheets
Reply:HTML is hyper text markup language. HTML was designed to display data and to focus on how data looks.





PHP (recursive acronym for "PHP: Hypertext Preprocessor") is a widely-used Open Source general-purpose server side scripting language that is especially suited for Web development and can be embedded into HTML





ASP is Active server pages widely used as Server side scripting language.





XML is Extensible Markup Language. XML was designed to describe data and to focus on what data is.





CSS is Cascading Style Sheets control the style and layout of multiple Web pages all at once.
Reply:ASP, a specification for a dynamically created Web page with a .ASP extension that utilizes ActiveX scripting -- usually VB Script or Jscript code.


ASPs are similar to CGI scripts, but they enable Visual Basic programmers to work with familiar tools.





PHP can perform any task that any CGI program can do, but its strength lies in its compatibility with many types of databases. Also, PHP can talk across networks using IMAP, SNMP, NNTP, POP3, or HTTP.





HTML, protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands.





XML, allows designers to create their own customized tags, enabling the definition, transmission, validation, and interpretation of data between applications and between organizations.





CSS, a new feature being added to HTML that gives both Web site developers and users more control over how pages are displayed. With CSS, designers and users can create style sheets that define how different elements, such as headers and links, appear.
