What is World Wide Web

world wide web
The World Wide Web (abbreviated as the Web or WWW) is a system of Internet servers that supports hypertext to access several Internet protocols on a single interface. Almost every protocol type available on the Internet is accessible on the Web. This includes e-mail, FTP, Telnet, and Usenet News. In addition to these, the World Wide Web has its own protocol: Hyper Text Transfer Protocol, or HTTP. These protocols will be explained later in this document.

The World Wide Web, also known as the Web or WWW, is a system of interconnected documents and resources, linked by hyperlinks and URLs (Uniform Resource Locators) that can be accessed over the internet. It is a network of online content that allows users to access and share information from around the world.

The World Wide Web was created in 1989 by Sir Tim Berners-Lee, a British computer scientist, while working at CERN, the European Organization for Nuclear Research. Berners-Lee envisioned a way to share scientific information easily and quickly across a global network of computers. He developed the first Web browser and the first Web server, which allowed the exchange of information over the internet using a standardized language called HTML (Hypertext Markup Language).

The World Wide Web provides a single interface for accessing all these protocols. This creates a convenient and user-friendly environment. It is no longer necessary to be conversant in these protocols within separate, command-level environments. The Web gathers together these protocols into a single system. Because of this feature, and because of the Web's ability to work with multimedia and advanced programming languages, the Web is the fastest-growing component of the Internet.

The operation of the Web relies primarily on hypertext as its means of information retrieval. Hyper Text is a document containing words that connect to other documents. These words are called links and are selectable by the user. A single hypertext document can contain links to many documents. In the context of the Web, words or graphics may serve as links to other documents, images, video, and sound. Links may or may not follow a logical path, as each connection is programmed by the creator of the source document. Overall, the Web contains a complex virtual web of connections among a vast number of documents, graphics, videos, and sounds.

Producing hypertext for the Web is accomplished by creating documents with a language called Hyper Text Markup Language, or HTML. With HTML, tags are placed within the text to accomplish document formatting, visual features such as font size, italics and bold, and the creation of hypertext links. Graphics and multimedia may also be incorporated into an HTML document. HTML is an evolving language, with new tags being added as each upgrade of the language is developed and released. The World Wide Web Consortium (W3C), led by Web founder Tim Berners-Lee, coordinates the efforts of standardizing HTML. The W3C now calls the language XHTML and considers it to be an application of the XML language standard.

The World Wide Web consists of millions of web pages that can be accessed using a web browser, such as Google Chrome, Mozilla Firefox, or Microsoft Edge. Each web page can contain various types of content, such as text, images, videos, audio files, and interactive elements. Web pages are hosted on web servers located around the world, and they can be accessed using a URL or a hyperlink.

The World Wide Web has revolutionized the way people access and share information, and it has transformed many aspects of modern society, such as education, commerce, entertainment, and communication. Today, the Web is an essential tool for people around the world to connect, learn, and share knowledge and ideas.

The Web provides a vast array of experiences including multimedia presentations, real-time collaboration, interactive pages, radio and television broadcasts, and the automatic "push" of information to a client computer. Programming languages such as Java, JavaScript, Visual Basic, Cold Fusion and XML are extending the capabilities of the Web. A growing amount of information on the Web is served dynamically from content stored in databases. The Web is therefore not a fixed entity, but one that is in a constant state of development and flux.
