The World Wide Web (WWW), commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext, and accessible over the Internet. The resources of the Web are transferred via the Hypertext Transfer Protocol (HTTP) and can be accessed by users through a web browser.

History

The World Wide Web was invented by Tim Berners-Lee in 1989 while working at CERN, the European Organization for Nuclear Research. Berners-Lee's vision was to create a system that would allow researchers to share information easily across different types of computers and networks. The first website was launched on August 6, 1991, and it provided information about the World Wide Web project itself.

Components

The World Wide Web consists of several key components:

Web Browsers

Web browsers are software applications used to access the information on the Web. Popular web browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari.

Web Servers

Web servers are computers that store and serve web pages to users. They respond to requests from web browsers and deliver the requested web pages using HTTP.

Hypertext

Hypertext is text displayed on a computer display or other electronic devices with references (hyperlinks) to other text that the reader can immediately access. Hypertext is a fundamental concept of the Web, allowing users to navigate between web pages.

URLs

A Uniform Resource Locator (URL) is the address used to access a web resource. It specifies the location of a resource on the Internet and the protocol used to access it.

Technologies

The World Wide Web relies on several technologies to function:

HTML

Hypertext Markup Language (HTML) is the standard markup language used to create web pages. It provides the structure of a web page and allows the embedding of images, text, and other media.

CSS

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in HTML. CSS allows web developers to separate content from design, making it easier to maintain and update web pages.

JavaScript

JavaScript is a programming language that enables interactive web pages. It is an essential part of web applications, allowing for dynamic content and user interaction.

Impact

The World Wide Web has had a profound impact on society, transforming how people communicate, access information, and conduct business. It has enabled the rise of e-commerce, social media, and online education, among other things.
