The World Wide Web (WWW or simply the Web) is an information system that enables documents and other resources to be accessed over the Internet, using web browsers. Tim Berners-Lee, an English engineer and computer scientist, invented the World Wide Web in 1989. It fundamentally transformed how information is shared and accessed around the globe.
Components of the World Wide Web
URL (Uniform Resource Locator)
A URL is the address of a resource on the internet. It is used to identify and access web pages through a browser. For example, https://www.example.com.
HTTP/HTTPS (Hypertext Transfer Protocol)
HTTP and its secure version, HTTPS, are protocols for transferring hypertext requests and information on the internet. HTTPS encrypts data for secure communication.
HTML (Hypertext Markup Language)
HTML is the standard language for creating web pages and web applications. HTML elements form the building blocks of web pages.
Web Browsers
Browsers like Google Chrome, Firefox, and Safari are software applications that interpret and display the HTML, providing a graphical interface for users to navigate the Web.
Historical Context
Tim Berners-Lee proposed the World Wide Web while working at CERN in 1989. By 1991, the first website, “http://info.cern.ch,” was published and made accessible. The development of web browsers like Mosaic in 1993 significantly contributed to the Web’s explosion in popularity.
Applications and Usage
Communication
The Web enables email services, social media platforms, and instant messaging.
Information and Research
It serves as a vast repository of information through websites, online libraries, and academic journals.
E-Commerce
Online marketplaces like Amazon and eBay revolutionize the retail sector, allowing for instant purchases from around the world.
Entertainment
Streaming services, online games, and multimedia content are accessible through the Web, dramatically changing how people consume media.
Comparing the Web and Other Technologies
World Wide Web vs. The Internet
The Internet is the global network of interconnected computers, while the World Wide Web is a system of interlinked hypertext documents accessed through the Internet.
