=What is it?=

The World Wide Web (as known as the "WWW" or the "Web") is a global information which allow people to view and to interact with a lot of sources and information, including books magazines, news, library resources and even computer programs. It can be accessed by computers that are connected to computer networks. The World Wide Web was developed in 1989 by [|Tim Berners-Lee], who is now the Director of the [|W3C] (as known as the “World Wide Web Consortium”).

WWW resources are organized to allow its users to travel from one resource to another. Users generally navigate through the WWW by using an application – WWW browser client. The browser presents formatted sound, images, text and other objects, such as the hyperlink, in the form of the WWW page on the computer screen. Any user can click on hyperlinks with the cursor to navigate to other WWW pages on the server, or the same source computer, or on other WWW server from world wide.

The WWW page is formatted using [|HTML] (as known as Hypertext Markup Language), and information is transferred among computers on the WWW using HTTP (as known as Hypertext Transfer Protocol). Special programs can also be added to web pages, such as Java, programming language that is independent of a computer’s operating system. Java-enable web browsers use applets that run within the context of HTML-formatted documents. With these applets animation and greater interactively can be added to any web page.

=Basic Terms=

The World Wide Web can be divided into four basic ideas: 1. **Hypertext**: It allows users to move from one part of the document to the other. 2. **Resource identifiers**: It helps to locate a particular resource on the network through a unique identifier. 3. The **client-****server** model of computing: It allows client software makes requests of server software that provides the client with resources or services. 4. **Markup language**: All characters or codes rooted in text indicate to a computer how to display or to print the text.

=How it Works=

Steps: 1. When viewers want to access a web page on the World Wide Web, they need to begin by typing the URL (also known as Uniform Resource Locator) into their web browser or they can also follow a hypertext link. 2. Then an HTTP request will be sent to the web server working at that IP address. 3. In typical web page, all the HTML text, graphic and other files form a part of the page will be requested and returned to the web browser. 4. The web browser will render the page as described by the HTML, CSS and other files received incorporating the images, links and other resources as necessary. 5. The process produce images allow viewer to see the on-screen ‘page’.

=Web Standard=

The Web is made up by three standards: 1. URL: As known as the Uniform Resource Identifier or Uniform Resource Locator, it is a universal system for referencing resources on the web. 2. HTTP: As known as Hypertext Transfer Protocol, it specifies how the browser and server communicate with each other. 3. HTML: As known as Hypertext Markup Language, it is used to define the structure and content of hypertext documents.
