The World Wide Web (WWW), also known as the Web, is a global network of information that can be accessed through the internet. It consists of interconnected hypertext documents and other web resources, which are identified by Uniform Resource Locators (URLs). Users can access the Web using web browsers such as Google Chrome, Mozilla Firefox, and Safari.
The World Wide Web was invented by Tim Berners-Lee in 1989 at CERN, the European Organization for Nuclear Research in Switzerland. Berners-Lee developed the Hypertext Transfer Protocol (HTTP), the Hypertext Markup Language (HTML), and the first web browser, WorldWideWeb (later renamed Nexus). These technologies allowed users to create and share documents on the internet, and to link them together using hyperlinks.
The World Wide Web quickly became popular, and by the mid-1990s it had become the primary way for people to access information online. Today, the Web is used for a wide variety of purposes, including:
- Information retrieval: The Web is the world's largest library, with billions of pages of text, images, videos, and other resources.
- Communication: The Web is used for email, instant messaging, social networking, and other forms of communication.
- Commerce: The Web is used for online shopping, banking, and other financial transactions.
- Entertainment: The Web is used for gaming, watching movies and TV shows, and listening to music.
- Education: The Web is used for online learning, research, and reference.
The World Wide Web is constantly evolving, and new technologies are being developed all the time. However, the basic principles of the Web remain the same: it is a global network of interconnected documents that can be accessed through the internet.
