Web Is a Technology consist of Client side technology and Server side technology Client Side Technology Is a Technology which use to show required document to user of web Server Side Technology Is a Technology which use to process data to produce required document Communicator Is a Technology which use to communicate client side with server

Types of Data Delivery (Process to Process)  Document Specific Technology Means which technology that use to display different type of document to the user/client of web.  When a user request to server using web browser for any type of content then server process this request and send back to browser.  When processed document come back to browser then browser show this document to appropriate position and sequence.  For this type of process browser’s need to use some technology which specified the document.

HTML – Hypertext Markup Language SMIL – Synchronized Multimedia Integration Language XSL – eXtensible Stylesheet Language XML – eXtensible Markup Language SVG – Scalable Vector Graphics

CSS – Cascading style sheet JavaScript – For Dynamic display

HTML stands for Hyper Text Markup Language HTML elements are the building blocks of HTML pages HTML describes the structure of Web pages using markup HTML elements are represented by tags Browsers do not display the HTML tags, but use them to render the content of the page HTML is the standard markup language for creating Web pages

Some Important HTML Tags Defines this document to be HTML5 The root element of an HTML page Contains meta information about the document Specifies a title for the document Contains the visible page content Defines a large heading Defines a paragraph Defines a link with other page

XML - eXtensible Markup Language XML is a software- and hardware-independent tool for storing and transporting data XML stands for eXtensible Markup Language XML was designed to be self-descriptive XML was designed to store and transport data XML is a markup language much like HTML

XML is Self Descriptive with no predefine tags :30 Jeet Datta Reminder Don't forget me this weekend! HTMLXML vs XML was designed to carry data - with focus on what data is HTML was designed to display data - with focus on how data looks HTML tags are predefined XML tags are not predefined

Important XML Standards XML AJAX XML DTD XML DOM XML Schema XML Services

AJAX – Asynchronous JavaScript And XML AJAX is not a programming language it consists of JS and XML AJAX is a technique for accessing web servers from a web page Update a web page without reloading the page Receive data from a server - after the page has loaded Send data to a server - in the background DTD – Document Type Definition A DTD defines the structure of an XML document A DTD defines the legal elements of an XML document A DTD defines attributes of an XML document. For Example of DTD The XML DOM is a standard for how to get, change, add, or delete XML elements. an XML Schema is to define the legal building blocks of an XML document DOM – Document Object Model

XSL – eXtensible Stylesheet Language XSL style sheet for XML file XSL Consists of Four Parts XML does not use predefined tags, and therefore the meaning of each tag is not well understood. XSLT - a language for transforming XML documents XPath - a language for navigating in XML documents XSL-FO - a language for formatting XML documents XQuery - a language for querying XML documents

SVG – Scalable Vector Graphics Scalable Vector Graphics (SVG) is an XML-based markup language for describing two dimensional graphics. SVG defines Vector-Based Graphics in XML format. Above code generate this image in an web page

SMIL is a language based on XML that describes multimedia events and objects. It proposed in 1999 by the W3C. SMIL allows easily define and synchronize multimedia elements like video, sound, still images for web presentation and interaction. SMIL enable to divide multimedia content into separate files and streams, send them to a user’s computer individually and then displayed together.
